Hey Guys so this is my build it took near about a month to build this, did a lots of research before actually doing it. Here are the parts that i used:
4 x Turnigy 2209 28turn 1050kv 15A Outrunner
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=5687
9x5 props providing 800g of thrust
HK board v2.1
18-20A HK ESC
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6457
Frame:
1 in wide x 1/2 in deep and 10 inches long aluminum arms
120 mm x 120 mm: 2 nos 5 mm plywood boards for the base
Zippy 4000 mah 3s battery
and HK normal Tx Rx
I was trying maiden flight today but got smoke out of one of the ESC :( dont know how cos i programmed that esc and it was working fine.. then when i connected it with quad and rest of the motors got smoked :'(
Here are build pics
Everything together ;D
smokingggggggg... i saw smoke for sure but after removing the ESC doesnt looks like its smoked.. shall i test it again? what say guys??
Will soon post flight pics... ;)
Did you insulate the motor >> ESC wires with a heat shrink? And if you have a wattmeter, check how muany amps are being drawn, that might explain why they are smoking.
Yes i have insulated the motor and ESC wires with heat shrink but i guess it was stucked correctly. I have 20amps ESC and motors draws max 15 amps.. i guess that shud not be a problem right??
hay satya gupta does you connect rx battery section to the battery or connect the bind plug??? give me some suggestion that rx required battery or not.
rahulsahul: when you connect your ESC to your receiver, it takes power from ESC. Bind plug is used to bind a receiver with a Transmitter.. Rx do not require direct connection from batt. :thumbsup:

Yes, most ESCs come with an in-built BEC (battery eliminator circuit) that powers your Rx and servos (if you have any).

hey thanks to give me knowledge abt that
You are welcome rahul, we are here to help each other :)
hey satya gupta i have a one problem...which kind of cable are used for connect the receiver to the control board (male to male or other servo cable)
Male to male..
Satya bro don't use fried esc, it might damage motor too. Hows your quad? Is it flying now?
Dharmik bro i have to buy a new ESC, but before smoking i tested my quad once and it did lift off before tilting one side. I was not having a good stand to test a good flight then. But later when i added stands ESC betrayed me :(
Will test soon and post pics/videos one question bro, these pots how do i use them?? an how usefull are they??
Gyro pots? Which firmware you have loaded?
None.. using the one which comes along with it... I am yet to recv my AVR will get it in couple of days..
Ok means default + config that you have on hk board. If you have default firmware put all pots between 35-50% and trim them by single axis tuning. It will sure help you.
Thanks bro, but the thing is :D i don understand rotating which side will give 0 and which side will be 100 :D please help
For me 0% was extreme CCW position and 100% was extreme CW positon. But you can check that(no props) by moving yaw pot to zero either cw or ccw and throttle stick at full. The side where your esc enters into programming mode is your zero position.
Thanks bro.. will try that out :)
tested for the maiden today. well testing and tuning the pots took most of my batteries and the time i was about to fly it outdoor battery went off :( posting video in sometime.
Wanted to know my quad was tilting a lot in the beginning to its left, after lots of pot settings now it tilts less but once in a while it does. How do i correct it??
Vdo sorry for bad quality.. thanks to my sis for the commentary :giggle:
http://www.youtube.com/embed/MMyAiavI4LE
the moment it took off battery gave up... will try again tomorrow :thumbsup:
Nice test.. No sudden flips, so setup is perfect. You just need to trim it if it's tilts.
Dharmik bro trim what?? yeh trim kya hota hain?? transmitter wala trim ya something else of the board itself..
http://www.youtube.com/watch?v=MMyAiavI4LE
Yeah trim of tx. Slight variations can be fixed using trim.
hey ...gr8 work..
I m interested too...can u tell me the cost of building this...
And did u import the parts from HobbyKing HongKong..
also what shipment charges did you pay...
Sorry i am a newbie...
Yes everything is imported from HK shipment charges depends on how much your parcel weights..
But now you can get most of the stuffs from INDIAN rc sellers as well.

thanx for the quick reply mate...! :)
lol thanks i always stay logged in when i am in office ;) you see boss have no restrictions :D :giggle:
one more question mate.....how to charge the lipo battery...say a 3S 2200mah 20C lipo
You need a balance charger for that. And here is a video how to do it.
http://www.youtube.com/watch?v=BYFHQHQ1aD8
So ...you have this charger for your 4000mah battery?

Only if I too could get that. :(
As of now, I have gone to the arduino-level and tweaked the arduino code. It has got ample thrust now. But the gyro-direction was reversed, corrected it, but the quad flips over. See this video.
http://www.youtube.com/watch?v=fSjNAbCrrL0
I think I know a solution to this. There was some GYRO_ORIENTATION and ACC_ORIENTATION defined in the arduino code like (x,y,z) or (-x,-y,-z). And I need to select just the right set of (-,-,-) to get it flying. I'll try that. What do you all say? ??? ???
Test flight today

good, i think u have improved bro....... anyway u have a supporting family too unlike mine....... anyway my sujection is to choose a better park, or an open ground............
Try to hover it near ground. Don't go at much height. More the height more is the damage with crash.

Thanks bro, support is very important. Sometimes they do behave weird but rest of times they know that its something which i like to do...
@spitfire thanks for the suggestion, but i can not control it. Was trying to make it hover but it goes straight up..
Hi Satya
Im planning to order the same parts that you had mentioned earlier in this thread. Did the parts from HK arrive safely without any damage? which shipping option did you choose?
Yes everything was safely reached to me without any problem. I selected air mail.
http://www.youtube.com/watch?v=7gOFrsHkUbQ
view and reviews pleazzzzz
What's this? ???
oppps will replace the sound track and upload again..
And do that FAAASSST! I can't wait to see that video. ;D
Wow. Seems Baaz is fond of trees. The 'Real flight' was really good. Let my new ESC arrive, and till then, I'll keep my jealosuy alive! :giggle:
:hatsoff:
ya ya actually it needs a open ground. And buy 4 sets of ESC not individual, in my quad i have 2 sets of 2 different ESC so the motors starts with difference of split seconds. Jealousy :P
btw dude any idea where i can find carbon fiber sheets in India?? something like this http://www.hobbyking.com/hobbyking/store/__10442__Woven_Carbon_Fiber_Sheet_300x100_1_5MM_Thick_.html
Here is one more, same video with new sound track.
http://www.youtube.com/watch?v=TxuY7NSeF2Q
@SatyaGupta
I have been searching for WOVEN carbon fiber sheets in India since the last 2 months, but wasn't able to find any. :(
BTW, I bought the same brand and same A-rating ESC. So i think it hardly makes any difference if I calibrate the throttle.
exactly i thought the same, but trust me there is a difference. If you seen my video. First test in open ground, where the quad did a good rotation it was all on 40% throttle nothing else.. I had to adjust the trim to control that. Later i found that one of the motor is spinning slower that others. Changing the ESC fixed that :)
But i think i might be wrong dont know. btw how do you calibrate the throttle?? hear 2 beeps and move THR stick down right??
Quote from: satyagupta on May 09, 2012, 09:13:52 AM
btw how do you calibrate the throttle??
Yes, if it's HK SS series ESC, I followed these steps that I found REALLY helpful:
Hmmm i did the same but this is for battery selection.. Li-xx or Ni-xx
For battery settings, brake settings, see this manual: http://site.exceedrc.com/resource/product/volcano_esc_manual.pdf (http://site.exceedrc.com/resource/product/volcano_esc_manual.pdf)
Sorry for being late. Wonderful work. Loved it.
Thanks bro... :thumbsup: :thumbsup:
Atlast i m back with my modified quad and its video :giggle: i really worked hard this time, took ample of time in reading about the stuffs that i am planning to use for this quad.
Here are list of modifications to my quad
Frame: Turnigy Talon Carbon Fiber, nice sturdy and light weight.
ESC: HK Blue series 20A F-20 (and let me tell you they are just awesome my friends just awesome)
Motors: DT750 along with 1047 props (planning to upgrade to 1147 prop, have read a lot on RCG about DT750 and 1147 combo)
FC: KK2.0 board with LCD
and ya a new FlySky Radio (programmable one)
Actually i had finished the build a couple of weeks back but i was not getting time to test it outside, due to rains on weekends and office on weekdays :( but today rain gods had some heart for me and spared me from rain for couple of hours, water dried but the park where i usually test my quad was muddy so had no idea where to test it. Then my mum, yes mothers they always have great idea for their kids :giggle: "Beta why dont you try on road" i was like mom even a guy with a normal scooty drive it as its a hayabussa how do you expect me to try. But then there was no vehicle during that time. So atlast tried it out and yay see the results, please view in HD if possible.
http://www.youtube.com/watch?v=mGtzwCRM0dY
Now i am lift of my quad smoothly no major drift or yaw, landing for me is a problem (last 5 sec in the video there is a hard landing that cos i spotted a vehicle coming) i cant get it to land softly kind of learning that. But then i think i will get better with practice. So my next step would to land my quad smoothly no major drops. Then learning to move the quad front-back and left-right. Will keep posting updates.
Have to give a special thanks to Dharmik, bro you helped me a lot :) thanks a ton, a million :thumbsup:
Satya bro you done it finally!! Yes it flies fantastic, no doubt. It's all your hard work. I have same problem. I do fly in the street and it stays busy. That confine place makes me nervous giving much throttle.
Congrats satya bro!!! It flies very smooth. So, what next? :)
Thanks vineet :thumbsup: ya she flies smoothly but i am not able control it, so i would now practice a lot on
Smooth take off (i can do that now) ;D
Soft landing, no way near to this >:( :banghead:
left/right and front back movements,
After i have practiced enough and have a good control over it i will think about next stage then and you know that would be :D :giggle: :P
Quote from: satyagupta on September 04, 2012, 08:58:23 AM
.......and you know that would be :D :giggle: :P
FPV!!!!! ;D
:violent: shucks that was a top secret mission fella, you blew the cover :rofl: :rofl:
lol buddy I just wanted to leave everyone waiting for it ... ;D
Today i practiced on my quad too, replaced my quads props to 1147 Slowfy version and i am able to see a lot of difference.
Quad lifts off at 25% - 30% throttle.
Quad is lot more stable i would say, i guess previous props where not balanced and i never tried to balance them :D
And broke 2 pairs while practicing :D
Something i noticed is, after attaining a certain height the drifts and unwanted yaw is gone. I am still not able to learn smooth landing :banghead: :banghead: :banghead:
Somewhere i had read said by anwar bhai that "the best secret to land these things is to bring them down to a height where it hovers and let gravity do the rest" i tried this once but still want to try more on this.
I tried Forward and backward movement, as i was not flying at a great height i was not able to practice this much but now i have idea how the movements need to done.
One last thing, as i have changed my props the the thrust now is like a lot, the moment i move my throttle more than 10% i can see quad moving up from ground.. So all of a sudden quad lifted to a lot of height and it got stucked to tree :( and then it fell down from a height of like 10 feet or more :( and one of the arm cracked :banghead: :banghead: but i have spare :D i will be back in a week or so with a video :thumbsup:
Any one from Panvel in RCI want to know about a good open ground to practice a lot with such confine space i will loose like 2 pairs with every session :headscratch:
Yes you are right bro. Once you gain some height around 5-6feet, you will actually feel real hover capabilites. We are flying in very confine place where we won't see real magic of multis.
Exactly.... in every multi rotor video that you see on youtube you will see that its big open space either in fields or open beach..
Finally i am back with my quad, now have a lot of control over it. Lands smoothly, need to work more on it but still its good. I need to do some PID tunings i am not able to understand how to get that right. :headscratch: :headscratch:
http://www.youtube.com/watch?v=8Oq4Svk1q_E
BTW how to embed the video in the reply :headscratch: :headscratch:
Satyagupta That is really nice flying.. Now i am (:|~ to build one.. But need some more time to move to quads...
Anyway nice effort man saw some of your old video and you have improved a lot... :thumbsup: :thumbsup:
And about posting video i always take the video in a new tab and copy paste the url of that tab.. simple.. {:)} {:)}
Thanks arun it took almost 1 year (with couple months of break) for me to perfect it. Still lots of tuning but it will come with practice.
about adding video: it worked this time but was not working when i tried first time :headscratch:
i have one more video which is FPV but its 770 MB for 7:30 mins :o :o
Whhooo :o :o
But eager to see that also.. Just convert it and upload...
(:|~
yea but after sometime, going out of town for a week. Will convert and upload after i come back. BTW any good free video converters?? i tried movie maker but does not render video :(
Satya just search "Any Video Converter" . Link send via pm.
The best video converter in my opinion is 'Super' ...its very powerful and foc.
I second with swizera... Any video converter is the best among.. :thumbsup: :thumbsup: :thumbsup:
Any video converter Stand first... See this ;D ;D ;D
http://en.wikipedia.org/wiki/Comparison_of_video_converters
Great thanks for the list...
i am out of town and took laptop but the video is in the desktop :banghead: :banghead: shecks i have to wait for 7 days to reach home and covert and upload :(
That is okay...We should wait
Patience is the key element for an Rc ist

Wonderful flying Satya bro.
Thanks guys, i will get the fly my bird again on Saturday. Am planning to let he fly till she makes the battery dry ;) also i will post the FPV video of the first flight :thumbsup:
My first ever FPV :D :D :D
Date: 10th Feb
Duration: 7 min 29 second

hey hey... great man....
(:|~ to own one... >:D >:D >:D >:D
Keep going... {:)} {:)}
Wonderful Satya bro. Keep it up.
Thanks Dharmik brother
i have one question :headscratch: :headscratch:
i have not ever upgraded my KK LCD firmware ever its still 1.0 version. Newest is 1.5 do you advice me to upgrade it to the newest?
Satya bro there are five ver available 1.1, 1.2, 1.3, 1.4 and 1.5 over default firmware but only two versions have major changes 1.2 and 1.4. As i know all new KK2.0 boards have v1.2 preinstalled. V1.4 has improved self level codes. V1.5 has camera gimbal feature added recently.
So whats your advice shall i upgrade my boards firmware?? If yes then which version??
If it's flying good, better keep it as it is. I saw on rcg that some users having problem after upgrading firmware and some found it more useful. But incase if you want to upgrade fw later v1.4 is good. I have v1.4 flashed on my both quads.
Good flying Satya. My only concern are the children around. Since you are trying it out for the first time It would be nice if you could find a real open space with no body to distract you. Only a spotter around. That will get you to learn faster. But otherwise great going. I don't know if I'll be able to do that ever. but that's one of my dreams as well.
Quote from: dreamfly on February 17, 2013, 08:04:35 PMMy only concern are the children around
Thats my concern too sir, normally when i fly i have someone with me to alert me when anybody comes near me or quad. I am trying find a nice open space, but then this bird flies make so much noise that it attracts to many on lookers :giggle: :giggle:
I am just wishing you well. I am recovering from my Trauma you know, and it an't a good feeling. Beginning FPV in a park with children around ..... A BIG NO! from me
http://www.youtube.com/watch?v=buOYIwWoQrA
Yet another FPV:
Tried to gain height, controlling in breeze and some aggressive flying :thumbsup: ;D
Satya bro you have gained good control over it. Are you using fpv gear as well or Los flying?
I am using the HD camera from HK http://www.hobbyking.com/hobbyking/store/__17200__HD_Wing_Camera_1280x720p_30fps_5MP_CMOS.html
I was planning to use FPV KIT that i had in my store, but it had great demand and i had very few so i have to order that again for me to use it :D
Whats Los Flying brother??
Very good :D
Quick question, how much throttle do u give for takeoff? I only flew mine once but half I was going easy on throttle, about half way, it took about 5 seconds to takeoff, did a bit hover then I forgot I had to trim the right stick. So I left the left stick thinking its steady and hen it flipped :p not much damage, motor mount which I had lasercut from pvc broke but I have extra so no worries. But I'll work on it after boards, till then finding a simulator :p
So the hover depends on ratio of thrust/AUW (weight of your quad including everything)
I am using DT750 along with 1147 props generating 1100 grams of thrust each motor so its 1100 x 4 thats approx 4kg of thrust
My quad weighs around 1400 - 1500 grams so my quad lifts off at 25%-30% throttle. And it gains a lot of height with 50% throttle. I have never tried with more than 50% throttle except while trying aggressive flying.
For quads if you are learning then do try to get it at a height of atleast 5-6 feet (not more). Make sure that all your trims are correct. If you are using KK LCD board you can go to Receiver Test menu to test the input signals. Make sure you trim you radio so that you get all channels to 0
Yeah :D

this is my fav gained so much height. Was very breezy in afternoon time, but i could control it. My next aim to set up FPV and get good FPV GOOGLEs any suggestions :headscratch: :headscratch:
Nice!!
Very nice flight satya bro
thanks Dharmik :hatsoff:
Wow Satya bro. That's something I was looking at doing in the neeeeeear future. Great going!
Thanks sir, i really want to gain more height but i am kinda afraid that i might loose control and loose it or i might not be able to judge its speed and position and crash it badly.
Will soon add good FPV Flying, can you tell me whats the operating range of the FLYSKY 2.4Ghz 9ch radio?
"can you tell me whats the operating range of the FLYSKY 2.4Ghz 9ch radio?"
I would If I knew. Try this site, Might have something there:
