Post by: Dharmik on October 30, 2011, 02:08:28 PM
First of all i would like to thank following members for their direct or indirect help to complete my project. Mr.Anwar (to bring this forum for rc lovers) Mr.V.K.Singh (rcelectro) Mr.Pankaj (thehobbyshop) Mr.Rajath Mr.Sriker Mr.Dhiraj list is really long.
ok i would like to post my custom frame build pics first. i will post electronics config soon. test flight will take some time but i will post all information here.

ok friends here is landing arms design and leveling of my quadrotor.
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on November 06, 2011, 03:33:50 PM
I am going to use hollow plastic tubes(sketch pen) to pass them through bottom holes of each arm.

Post by: dhirajjadhaodhiraj on November 07, 2011, 12:04:29 PM
Hello dhramik. i can see in images that you have used 3 sided electrical wire casings for ARM. But this material is going to give you lot of vibretions and very less strength. And even this ARM can elevate from it's level if you give any rapid input to your quadrotor making it unstable. i will better suggest you to change the arm material or you can first try the frame for Vibration test by only putting one motor with prop on the ARM.
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on November 07, 2011, 12:33:51 PM
hi dhiraj bro thanks for your valuable comment. It's not electrical wire casing.it's OREVA power saver tubelight base casing 20mmx10mm and thickness is 2.5mm.i have aluminium square hollow rods available.as you said if this material gonna put me in trouble i will replace it with aluminium arm.i will perform test first.thanks a lot bro. EDIT thinkness 1.0-1.5mm

Hi thanks karan. Now it's your turn :p my quad is allmost completed waiting for outdoor test but ya it was really tough.i had to rewind one motor as it was fried(one esc too) during test, later i bought set of new motors. I have changed many things and at this moment i am using 2/3 inch aluminium channel but searching for 1/2 channel but as you know these things hardly available in our city.

Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on January 15, 2012, 11:20:26 AM
hi swapnil no yet tested outside. recently i bought 6ch radio from rcbazaar and trying to figure out how to program it, even upgraded battery and bought 2200mAh 3S 25C from rcelectro(received yesterday). Even changed arm and using 12mmx12mm aluminium channel and frame weight dramatically decreased :)

Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on January 30, 2012, 11:38:24 PM
nothing bro only the thing is progress is really slow especially when it comes to PID tuning. i need some suggestions.btw this one is kk v4.7 x config. it seems uneven surface causing quad to go crazy.
Title: Re: QUADROTOR from Bharuch
Post by: paladugu_sujith on January 30, 2012, 11:43:54 PM

Post by: Dharmik on January 31, 2012, 12:09:59 AM
@paladugu_sujith thanks bro i will try that in next test as rest all things seems to be ok so i am sure gyro needs some adjustment. @VC sir haha yeah this thing is really tough.i will edit my posts once i complete(hopefully..) this.

Post by: Dharmik on January 31, 2012, 12:24:17 AM
lol actually VC sir is right. Such video is probably pointless at this moment, since i am updating topic with all test videos i thought to post this one too it might help someone having same issue but i will have to edit topic as this is my 4th custom frame and new set of motors etc to list them above.

Post by: Dharmik on February 04, 2012, 12:36:17 PM
Finally after doing some tweaks with gyro i found correct gyro gain(i kept P gain bit high in this video), believe me it was not that much of easy when props attached. I went through the whole PID tuning, still i am not satisfied, some work needed before outdoor test. All this happened between 45-60% THROTTLE RANGE. I would like to thank Chris(LazyZero) for his assistance. http://www.youtube.com/watch?v=Lc8OyeTy13M&feature=youtu.be
Title: Re: QUADROTOR from Bharuch
Post by: paladugu_sujith on February 04, 2012, 01:01:36 PM
i had the similar issue .. reduce the gain bit by bit till u get a normal flight.. . what LIPO are u using. is it over 30 C discharge?? or less than that. if u are using hk control board make sure that is its properly mounted on a double sided tape.. it shld have almost 0 vibration. i saw that when one of the arm was dipping.. the gyro was over correcting it. reducing the gain would help ..
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on February 04, 2012, 01:19:49 PM
hi sujith Thanks bro. Motor's max current is 6-12A. i am using 2200mAh 25C lipo. Yeah you are right gain was bit high causing oscillations, will decrease a bit today. It was moving around as i have been triming tx during that but results are much better than my last test.
Title: Re: QUADROTOR from Bharuch
Post by: paladugu_sujith on February 04, 2012, 01:27:47 PM
12 a X 4 motors need 48 amps of current.. ie close to 50 amps of constant current. 25c will not give enough current for it. 25C will give max of 25X 2200mah ie 50 amps of current.. just filling its need..put a 40 c lipo.. and chk it.. you shld be able to hover it. and yes gain is always a sensitive issue . make all the gain changes 1/8 of the turns .. slowly decreasing or increasing it depending upon need.. hope this helps. would love to see this beauty hovering soon.

Finally perfect gain, perfect trim and perfect performance that i have been looking for. http://www.youtube.com/watch?v=efYUclbUH1k&feature=youtu.be
-1100 kv motors -20A ESCs -2200mAh 25C battery -10x4.5 and 9x5 props both giving stable performance. -HK 48PA FC. -Cricket bat grip material to reduce vibrations. -Always balance your props and see the magic

Hey friends, after last outdoor crash i have rebuilt my quad again. It flew really well, more than two minutes in perfect hover position, however at last due to lack of skills i crashed it from above 10 feet. Luckily everything survived except frame and motor shafts and cap of roll gyro came off. I am really satisfied with hk board performance so i went ahead and put everything together.

What material are you using for the base, where you mount the HK board...
Title: Re: QUADROTOR from Bharuch

Post by: satyagupta on May 02, 2012, 09:55:42 AM
Bro any suggestion where would i something like that???
If you see the latest post by me here, http://www.rcindia.org/multirotors/help-with-my-quad/ i used a 2 mm plys which gave up after a hard landing.
Was thinking to use something very light and stiff, any suggestions??
BTW i got a good flight yesterday :) was able to lift my quad more than 20-25 feet in air :D will post video soon.

{:)} {:)} super stuff Dharmik.
Bro i have got into a problem with my quad :headscratch: if you rem at the very start my quad used to do round and round on the yaw axis. After sometime getting some inputs from you and other members of RCI i got it fixed. Now i have replaced the base with a 2mm CF plates and it has started the behaviour again. The only thing is different that its more violent now.. It rotates as if its on mission to kill someone :banghead: :banghead:
Any inputs, sorry i cant took any video because it was very dangerously flying so i had to stop in less than a minute or two.
Title: Re: QUADROTOR from Bharuch
Post by: storehyd on May 24, 2012, 09:40:52 AM
@satyagupta
Yes i got your point that rotating roundly.
it happens when CW and CCW (Clock wise and Anti Clockwise) aren't correctly placed. just be aware of the Front, Rear, Right, Left. here is an example for that---X config.(works perfectly)
Left
CCW X X CW
Rear + Front
CW X X CCW
Right
***This is a method done by using IMU 6DOF.(Front,rear,right,left) It depends on how you actually placed your Gyro Sensor. Above you can see Gyro Front-Rear-Right-Left. According to your Gyro Position you need to place your propellors CW and CCW.

Satya bro i don't know which fw you have flashed but i had to reverse my yaw gyro on kk 4.7 fw but as you said it started again then probably something wrong with new setup. It also happens when arm is slightly twisted by mistake so make sure motors are mounted at 90 degree angle. Btw i will have to remove background music(content id match) p

What happend satya bro? My previous harness was bit long. All i learned is make ESS to BATTERY connection as much short as you can. You can extend esc to motor connection if required. Yeah heat shrinking left. I have added wires for lights too.

QuadRotor - Navigation lights test I have changed gyro gain a bit, it was flying everywhere due to new gain settings and windy condition. I will revert back to old settings. Well nav light circuit was sent by roopesh sir so i am really thankful to him. It adds beauty. Searching one red or blue 1W led. Here is short video. http://www.youtube.com/watch?v=aFUOM_YYN8g

Yeah Satya bro wind gust and i was trying to fly it near the ground. I think it can be improved bit more but needs open place. But i am sure simonk firmware makes huge difference now.

Post by: Dharmik on August 10, 2012, 06:13:20 PM
Have you flashed your ESC? I heard that flashed esc gets warm but mine stays cool just as before. I don't see any negative point. But ya i am experiencing bit yaw drift. I will try to fix that.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on August 10, 2012, 07:10:14 PM
one more doubt, reflashed ESCs cannot be programmed via card, so what if we want to change any settings? (say, timing, or LV cut-off, or anyother) Thanks

No bro i havent but i want to first try with non flashed ESC, then i will flash them. But i am still undecided on it :headscratch: what do you say shall i FLASH my ESC??
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on August 10, 2012, 08:16:11 PM
@Vineet bro once you flash esc you can not change any settings except throttle range but best possible multirotor settings are allready covered and included in the firmware. @raja_mastana sir i have been playing with PI gain from past few days over rooftop. Currently i have P gain at 100 and I gain at 50. Yaw P gain 120 and I default. @Satya bro ya you are correct first try with non flashed esc.

Post by: hyd_quads on August 10, 2012, 09:20:27 PM
@Dharmik: I read once an ESC is flashed, we need not do any throttle calib. (although it CAN be done). The new f/w hard-sets the throttle range to 1000-2000.
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on August 10, 2012, 09:39:38 PM
Ya i read that somewhere and i was also expecting that but when i powered up my esc motor refused to start. Maybe the reason was my end points were set to 120.

Post by: Dharmik on September 02, 2012, 09:16:56 PM
@Satya bro i think DT750 has 4mm shaft so you don't need to cut. I do mount prop near the bell to get rid of vibrations and it actually works. @Swapnil bro that's HK board. I was using KapteinKuk v4.7 firmware. You can flash firmware using USBASP. You won't believe but that board is one of simplest board available at this moment and firmware was readymade(not coded by me) but still it took more than 5-6months to get 1st flight.

Some major changes
1. I bought 8x4.5 gemfan props recently for some tests, i have been using 10x4.5 till now. Test results ADVANTAGES - More stability and control. - Able to handle wind gusts. DISADVANTAGES - Lifts of at 50-52% throttle(before it was 47-49%). - Spacer ring of these props doesn't fits well on the 3mm shaft so i got prop adapters now.
2. These props have 5mm hub so i bought brand new prop adapters from RCB. Now prop fits perfectly with them.
3. And now one of the biggest change, i have replaced old reworked shafts with hextronik motor shafts. Looks simple task but it took 2-3hrs. Damn grub screws you know.. See how beautiful they are with new makeover.
Check pics below. Motors with replaced shafts, new adapters and old shafts(one broke during reworked operation)

Post by: Dharmik on September 17, 2012, 12:38:24 PM
Yeah bro, one possible reason is i was flying with stock settings(P gain 50) of v1.2 firmware which is really low for simonized ESCs. I just tweaked I gain and I limit during that, if you watch video very closely you will notice low frequency wobble. In rapidESC video they were at 100.

@spitfire I bought them from here, i see GF written on it. I would say they are really strong and less balancing required. 2 pairs (they are in the above last 3 videos) http://rchobbyaddict.com/product_info.php?products_id=436&osCsid=be62aa1308045395b9d5a99d566024ed 3 pairs (still NIB) http://www.rcbazaar.com/products/1217-quadcopter-propellers-8-x-45.aspx
@Satya bro you were absolutely right and now it's confirmed that these things are more stable at 4-5 feet and above, hard to get stable hover near the ground due to air turbulence. Yeah i have tweaked with gain settings in the above video. I will power up the board and post exact settings here but they were between 100-150 on P.

Dharmik Bhai, Where did you buy those hextronik motor shafts from. Are they for the DT750's??
I have been plagued by crashes off late and am re-building my quad once again. The recent one was a ESC failure and pop! into a pond over which I was hovering.... Camera and all. I am still drying my camera and haven't switched it on as yet. Total loss as follows: 1. 2 F-30 ESC's (one smoked before the drop and the other probably shorted after it hit the water). 2. 2 APC props 3. Sony DSC - WX 150. Yet to determine the loss. 4. 4 Bent motor shafts (DT750)
I have seen that you have started hovering your quad well. I cannot view the video from my office comp since youtube is not allowed. Will go home and check. I haven't logged into this forum in almost a month now.

WOW!!! Dreamfly sir, where were you been? Missed you. Believe me i am really happy to see real hero back on the board. Oh and sorry to hear about that. As you know i am using these motors for my quad but their 65mm long shafts are unnecessarily long. http://www.hobbyking.com/hobbyking/store/__5429__AX_2308N_1100kv_brushless_Micro_Motor.html After that initial crash i was planning to replace them but couldn't find 3mm shaft anywhere. I found 3.17mm more popular nowadays. I didn't know that the solution was with me allready. I have 4 x hextronix 24grams motors in the house(i was thinking to sell them). http://www.hobbyking.com/hobbyking/store/__5208__hexTronik_24gram_Brushless_Outrunner_1700kv.html They have 45mm shaft. I just replaced them with old shafts. Now it's perfect and new adapters bought from rcbazaar fits perfectly on it. And best part is vibrations are greatly reduced. Sir may i ask you that is this the motor that you are using? http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6247 I think its shaft(80mm) is too long. If you are planning to replace them get short shaft and new 4mm adapters and i am sure you will be surprized with the performance. Check aeroworks.co.in, rcbazaar and rcdhamaka they stock 4mm shafts of different length.

Thanks Dharmik Bhai, I am also very surprised as to how the esc could burn out. I have attached a pic for you to see.
The shaft pic's look a bit different.... in that they do not have the thread. How did you remove the shaft from the bell? I tried it once after removing the single grub screw attached on the top of the bell but the shaft wouldn't budge. Do we have to bang it out with a hammer?

hey Hyd_quad, I am glad to be back. Had a lot of crashes off late. Guess my stars were not aligned.!!!! Anyway I am re-building the quad and should be up in the air. Drying off my electronics since they fell into the water. I have tested them all and they seem to be fine. I love my OP board. Hey I sold the Naza to a friend in delhi and guess what!!!!!!!!!!!!!! I was told that the quad flew away!!!!! I really feel soooo bad for him for loosing the quad + board+ motors and all that was flying with it. I really hope he finds it. That's the problem with the Naza I think but I didn't have any such problems with it. Wonder what really happened. Poor chap.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on September 23, 2012, 08:56:25 AM
Perhaps it was a problem with the radio? Was there anything equivalent to failsafe? Was it a flysky/turnigy/hobbyking radio? If yes, then the receiver (the OEM of all these is flysky) sends the last receivd signal to the FC incase of signal loss. So if it was flying before the singal got cut, it will continue to fly!!! This happened with me once (with props off), whenever I switch off the radio when my board is armed with some throttle, the throttle continued until the signal was back and I reduced it = flysky sends the last received signal until signal is back.
Title: Re: QUADROTOR from Bharuch
Post by: raja_mastana on September 23, 2012, 10:05:16 AM
After reading this i decided to try what happens on my quad once single is lost. It went to full throttle! >:D I then immediately switched the Tx back on and it came back to normal. I haven't setup failsafe correctly or forgot about it completely - will figure it out
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on September 23, 2012, 10:07:53 AM
Which FC was that? In multiwii there's a #define named MOTOR_STOP that enables/disables the feature you mentioned. I always like to have it uncommented so that the motors don't spin up when I accidentally switch the Tx off (with board armed).
Title: Re: QUADROTOR from Bharuch
Post by: raja_mastana on September 23, 2012, 10:13:01 AM

Well all I can say is that the Naza could still be way off being a production FC. I think a lot of testing is still required after reading these posts. We are happy to see a product from the outside.... But when it flies away from you... That's when the bashing starts. Well it could happen to any FC but some lessons to be learnt here. May be I was just lucky and survived the fly-off.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on September 23, 2012, 02:56:13 PM
It doesn't seem to be naza's fault at all, i think it's an issue with the radio. Btw, what did that guy do? Did he start searching for it, and did you ask his opinion as to what he thinks might have caused the quad to fly away?
Title: Re: QUADROTOR from Bharuch

Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 23, 2012, 04:42:26 PM
I too dont believe that naza has any issues. Yes my friend used the Turnigy Transmitter which is a 2.4GHZ. If the Naza has the RTH it should have worked flawlessly. Also when the transmitter was turned off, which my friend was actually trying out, it should have stayed put and not start going higher and higher very slowly. The Naza has to go only upto 20 ft and then RTH. Where was the FC getting the signal from to go higher and higher when the transmitter was turned off.... I Don't get it. Well May be it was the transmitter, But what when it was turned off? He is still searching for it. No word of it as yet. Really hope he finds it soon.

It is a good question. I also understand that setting failsafe will solve the problem i.e. whatever position the Tx stick was during the bind process, the Rx would go to that setting whenever signal is lost. Normally we set failsafe to 0 throttle.
What i don't understand is; (assuming failsafe is not set) what causes this full throttle at signal loss?
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 24, 2012, 03:12:56 PM
Raja_mastana, On Naza the failsafe feature is set using software. It's a very simple click of the mouse. and it's done. On the other FC's we use the bind process and when there is loss of signal the quad just slowly decends or falls to the ground instead of flying away. On the Naza though there are 2 failsafe settings. 1. To land immediately 2. To RTH and land.
I have heard of the Naza flying away on some other forums as well and since there is no way we can set the binding process unlike other FC's we are at the mercy of the software. That's one big drawback of the naza. When it flies, it really flies like a dream but there are not many fine tuning features one can tweak with.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on September 24, 2012, 10:39:21 PM
That's why i call it an iFC (note, 'i' does NOT stand for intelligent) I don't mean to offend you, but naza is just pure proprietery crap. The protocols, sensors, processors and platforms are all either proprietary or undiscolsed. No question of tweaking anything/anywhere... I guess tht is why u switched to OP?
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 25, 2012, 10:05:59 AM
For me the fun lies in the Tweaking. May be for some others it lies in the flying. I want to spend time tweaking and looking at the GCS. and once we get into the tweaking. I guess no other Closed source FC's are going to be fun to work with. I have also looked at the other Open source like the multiwii and they also can be fine tuned. Mr. Ashta uses the Multiwii interface to tune his copter and you wont believe how well his copter flies even with most of the propellers and motors way out of balance. The opensource community is spewing out quality code these days and it's just a matter of time when every body can fly the quad.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on September 25, 2012, 10:13:05 AM
So true... more fun lies in tweaking but then it depends on the user too. Yeah, I am aware of ashta sir's multiwii. It flies great.
I have switched to the AfroFlight (32-bit multiwii) community now! This ~$70 board (with it's 32-bit cpu) is comparable to most ~$150 FCs and is completely open-source! All four sensors are integrated onto a small 36mm x 36mm board with an onboard serial programmer too. Has gps, bluetooth and CPPM rx supprt too. ;D

OK. I believe 32 bit or 16 has nothing to do with it. Mikrokopter is a good example. Their FC flew with I think 8 bit processor but just look at how steadily it flew. It's all in the software.

check out my Y6 buiid. Flew it once already. Trying to modifying it now and add some extra fittings.

Post by: hyd_quads on September 26, 2012, 03:37:51 PM
I first thought it's all in the sensors and their precision mattered a lot. Then I thought the software itself made all the differnece, and some said it's all about the CPU. Then naze has all three. :) But what you say is right too. Are you sure MK is only 8-bit?
If not Naze32, my next choice was a ~$70 multiwii (CRIUS all-in-one pro) (8-bit again) It was a good large board, stuffed with features and optional extensions (easy I2C GPS setup, optional OSD, etc..) It was ~$15 cheaper too. I like the naze but I'm hating the feeling that I made a mistake by buying the Naze. I'm really confused here.

Well those are plans for the future releases. Nothing works as of now. This will probably take may be a year or so
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 26, 2012, 04:03:15 PM
Hey I said MK started off as an 8 bit. 8-bit isn't viable any more since the processor is subject to a lot of processing with the umpteen number of extra modules (GPS, baro, etc etc.) But for a simple stabilization only FC (gyro + accel) 8 bit should be sufficient I used to follow their build from the very beginning somewhere in 2007 and I am sure they used only an 8 bit those days.
You know something. The "NAZE" is a fantastic FC. and I feel it's more advanced than the OP. (Designed by a Japanese) The problem with these controllers are that if you get used to one then all others feel inferior. (The reason I sold my Naza) even though Naza flies out of the box. If you look very closely at the op and the "NAZE", they look very similar both in design and the components they use. Please don't regret buying the Naze and 32 bit processing is all the more better for future software upgrades.

Oh, so you're dealing with timecop too. He's a nice guy to buy from. btw, what makes you say the NazE is more advanced than OP? And do you know if GPS can be hooked up to the NazE? I heard I2C GPS is not supported. But how do I connect a UART GPS, there are no pins on the board!
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 26, 2012, 04:39:52 PM
Yes I do interact with TC. One day I asked him if he doesn't sleep and he said he doesn't. Don't know if he was joking or serious. He is a very knowledgable guy. Infact you should ask him these questons on the GPS, and if it can be supported. BTW are you a developer? or just a avid quad lover like me?
I believe that anything can be done in electronics and if it can't then you make it happen if you know what you are doing. You just hack it.

Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on September 27, 2012, 06:16:45 PM
yes, wheneven I fly with a camera onboard, I'll use the Y6, and I'll use the quad for fun flying. I mentioned about a failed ECS in my earlier posts. I was flying over a small pond and the ESC just fried mid-air. Thankfully I wasn't flying very high. The extra motors are adding quite some weight no doubt. Cant be used for fun flying at all, and the battery drains fast as well. It looks and sounds really scary when it flies with all 6 blades ready to chop. I had infact a small cut on my forearm when I did my first test flight. Since there isn't a landing gear I launched her by hand and then one of the lower propellers kissed my arm. These props can draw blood quite easily. If using the APC props safety First!!!!

Post by: dreamfly on September 30, 2012, 12:11:31 AM
Finally got the CC3d in my hands today and Oh Boy was I excited!!!!!. Plugged it in,changed some pid settings and Off I flew it in my living. I am risking a lot by flying it indoors. already got a gash on my forearm. But my excitement got the better of me and here's the CC3D flying. First of all the software is still in Beta so I am still expecting quite some more changes in there. There are some changes in here from the original OPCC and I feel less experienced all of a sudden. I had earlier fine tuned my OPCC to the extent that it just flies hands free. With the CC3D I still have much to learn and knowing that the software hasn't still been released.... all I can say at this point in point in time is Let's Wait for the final release....... Here's me flying it anyway....

Okie.. I think it's an issue with driver or maybe something else. It gives me such error when it's not connected properly to the port. In fact i just tried it and it gave me an error "USB Device not recognized" so i just plugged it again properly and it works now. I do get such error while connecting simulator cable also and reconnect does the job.

It will give you that error even solid green light is on but don't flash an ESC without fixing that issue otherwise it might damage EEPROM of an ESC(i read that somewhere on rcg). So fix everything before you hit green button.

Post by: hyd_quads on September 30, 2012, 12:18:50 PM

Nopes, you know the strange thing this drifts these happens some times not always. If i move throttle from 0 - 40% in one shot then quad will jump and will be stable no much drift. But if i slowly move throttle there is lot of drifts man..
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on October 14, 2012, 09:38:38 PM
post a Video . Drift is always there. It's just a matter of how much. indoors there will definately be prop downwash and the quad will drift. Outdoors the quad is succeptable to breeze, so the quad is bound to drift. If you are looking at zero drift, you are asking for too much ;) If you mean hand free flying then you need to first tune your Quad as much as possible (PID). If you have something to adjust the Level on your board then please do that. I fly the Open pilot and we have something called "Leveling" which I have to first click to record the level on the FC. Not sure if it's there on the HK board

Extremely sorry for being late. Thank you Satya, Runik, Vinnet, Dreamfly bros. Friends i flew it on the ground today where it crashed before on my 1st test flight, audience crowded and enjoyed the flight(once again i flew it at night). Everything went smoothly, rapid ascend and descend, gained even more height. I will post video soon. @Satya bro if it's roaming around, you have to find optimum gain settings for your quad. If possible try it on small props, it will be easy to control. Don't worry it might take some time but once you gain experience it will be easy to overcome all these.
Title: Re: QUADROTOR from Bharuch
Post by: hyd_quads on October 15, 2012, 03:40:39 PM
So true. Most quads (esp. Multiwii) yaw-drift a little during take-off, but this is considered normal. I haven't heard of pitch-droft or roll drift.

DT750 they are the good or i would say awesome motors.. If you are ready to burn your pocket then i would suggest Tiger Motors http://www.rctigermotor.com/list.php?catid=65 i call them pocket burners.. ;P

Very true.. ;D People say any multirotor motor above $40 or so is only a rebranded, re-stickered $25 motor.. :giggle:
But sunnysky seems to be a very good option. Sunnysky is sold on goodluckbuy.com (http://goodluckbuy.com) and himodel.com (http://himodel.com). It is the best choice for those who want *super-smooth* cheap 22xx (http://www.goodluckbuy.com/sunnysky-angel-a2212-2212-980kv-brushless-motor-multicopter-kk-multi-copter-quadcopter.html) motors. Unfortunately their 28xx (http://www.goodluckbuy.com/sunnysky-x2820-800kv-outrunner-brushless-motor-for-quadcopter-multicopter.html) series are a bit costlier.

Well i can get sunnysky motors in my online store, if they have users here.. there is one more brand LEOPARD/RED LEOPARD they are also good but have not ever heard about it here in RCI.

Sunnysky motors are undoubtedly good, but unfortunately not many guys realise that they're actually better than turnigy, HK, etc. They tend to think sunnysky is just any other chineese motor.

So..friends(Dreamfly sir, Satya and Vineet bros), hows your RC life going?
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on November 15, 2012, 09:15:13 AM
For me it's only on weekends. I am building a new quad now. This one's a heavy lifter with Tiger motors. Still a long way to go. My Y6 motors (dt700) needs some new shafts, Props and bearings. Anybody knows where I can get some good japanese bearing 4x8x3 for my Dt700's?
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on November 15, 2012, 09:28:13 AM
Nice to hear from you sir. Have you dismantled your first quad? I do fly my quad regularly at night. I have some videos to share. My next quad project is bit delayed, few things left to buy. EDIT Here is the list of motor stuff http://www.rcbazaar.com/category/167-motor-shafts-bearings.aspx
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on November 15, 2012, 11:50:41 AM
I have not stopped flying. I am fine tuning my quad with some patches the developers have put out. Added to my misery my motor shafts are all bent and need to replace them along with the bearing. The y6 consumes a lot of power and I dont really get a lot of flight time, around 1 min or so on a 2200 and I only have 4 lips's. I have done too many purchases lately and need to put a hold on any more further purchases. This buying never stops really.
Title: Re: QUADROTOR from Bharuch
Post by: satyagupta on November 15, 2012, 02:17:20 PM
I have written my reply but forgot to press post :banghead:
ya so, today have plan to complete my quads new frame. I have moved from turnigy talon (arms used to bread with every crash >:( ) to our very own custom aluminum based frame, so that and then test and fly it again. Then my plan in near future is to build and try SPIDER FPV frame, i have got the materials just wanting for the right time i.e. i get a good control and get my quad flying. So it has around good couple of months time, but i have started gathering stuffs that would be helpful to build one.
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on November 15, 2012, 06:28:51 PM
When i started working on this project in the mid of 2010, i didn't even know that one day i will be able to land my quadrotor on less than 1x1 feet table. One slightly loose motor mount caused left yaw drift during this flight but everything went smoothly later and managed to finished the battery pack. To my surprise when i gained height some bees started roaming around the quad. Well i tried to land on the tripod as well but i couldn't may be next time. http://www.youtube.com/watch?v=WlJ-1IhQ94k

Dharmik Bhai, Good stool practice. Now I am not having a good time at all. Today I had another crash. Will post a video of it. Oh Boy was I lucky in all ways. Firstly It crashed on my rooftop, secondly I was not flying very high up and thridly only a broken moter mount. I dont know what went wrong. These are Tiger MT 3506 650 KV. Anybody heard anything bad about them. I was consulting on another forum and one person mentiond about motor stalling in flight. Now that is bad news for me. I am still counting my lucy stars!!!!!!

Post by: Dharmik on November 19, 2012, 08:47:53 PM
Hmm.. Sir i haven't tried those motors but i saw many positive reviews. May be something wrong with motor-esc combo? Have you flashed your escs?
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on November 19, 2012, 09:57:59 PM
I am planning to buy the flashing stuff and get along with the flashing exercise. Vineet has sent me your website with the tutorials on how to do it, and I want to do it at the earliest to prevent such mishaps from occuring . Man was I lucky. I just cant stop thinking about it. Even my dreams last night were not ok.
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on November 19, 2012, 10:21:08 PM
Sir may be it's something else and not motor or esc, because as you said it flew fine during tests.
Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on November 20, 2012, 08:43:57 AM
yes, it flew fine during tests but they were mostly indoors. So not much throttle play was used. Well I have to give it some thorough testing now. all while attaching the quad onto chairs of some other grounded objects. I have to be 100 % sure that this accident will not surface again. Am really disappointed with this performance right now.

Wow, That's a very narrow alley Dharmik Bhai, I don't know how you can make out the front from the back!!! May be some Red colored Led's might help. (But that's for me)
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on December 03, 2012, 12:30:51 AM
Dreamfly sir i have blue leds at the front and white at back, it helps but i think these are just basic FFF stunts, so many things yet to learn. 1 month spent on the simulator helps me now.

Post by: dreamfly on December 03, 2012, 08:50:26 AM
Dharmik Bhai, I remember I had asked you about a simulator and you had pointed me to some links . But I have forgotten about it. Since I am grounded now, I would like to fly on the simulator. Which one do you use?

Title: Re: QUADROTOR from Bharuch
Post by: dreamfly on December 03, 2012, 09:26:24 AM
I really don't have a clue on any simulator.... never used one. But I want to start using one to see if I can improve on my flying skills. I am grounded now for some time because of a scary crash almost on top of my son who was filming the quad flying. As I fix the issue I want to be able to also fly on the simulator. Is the Pheonix simulator for the Guai good? Did you buy it or download it for free?

Yes sir i am using Tx, i got my sim cable from Rajath bro. I will search and let you know. Have you checked Satya bro's site. He has 9in1 sim. It might work as well.

Hi Dharmik, I built a quadrotor recently with hobbyking kk board v2.1 shown at the link below.
My quadrotor is doing take off and landing as usual and i am using firmware minsoo kim 2.5 but i want to change it to kk 4.7 version since the quad is not very stable. I can't keep it hovering at a single place as you are doing in your videos. Please guide with the 4.7 firmware me so that i can achieve such stability in my quad copter.
Regards Rahul
Title: Re: QUADROTOR from Bharuch
Post by: Dharmik on January 27, 2013, 08:06:16 PM
Hi Rahul bro, Sorry for late reply. I haven't tried minsoo Kim's firmware but you have to tune your quad to get stable flight. Try increasing P gain and decreasing I gain. KK 4.7 has ability to adjust both gains separately but it requires to reverse gyro gain. I am using KK2.0 LCD version. Please let me know if you need any help.
