Ahh nice.. thats like 3-4 mins walk away from my house is stay Near Shabari hotel

rough mock up of the frame (not glued)

Subbu

i finished most of the build part of the quad these last few days

after discussion with sushil uncle opted for CA as the preferred glue for the frame. then finished gluing the frame together.

Sandeep uncle helped me finish soldering the connectors onto the ESC and batteries.

only the twin parallel battery to quad ESC power harness needs to be finished and the frames motor mounts to be modified to accept the X mounts that came with the motors. after the concern that satyagupta mentioned about the frame i have decided to insert in 2 10mm CF tubes through the design holes in the frame arm supports in an X fashion

photos of frame and electronics setup attached

Subbu

Good Luck for your build...

hi guys i recently burnt one esc of the quad is it advisable to put in a different esc in the same current range or should i buy a new one


Subbu

It is good to have all escs same else motors won't start in sync. It will affect stability.

thanks dharmik i am ordering 4 red brick 25 A esc from rcelectro since HK will take a lot of time for the replacement unless someone here at rcindia has a spare lying around

subbu

That's great bro. Get good quality programable ESCs. And make sure motor to esc and esc to battery connections don't short in any case, it will immediately burn esc and motor within seconds and you won't get chance to disconnect battery. Don't use tape or anything like that as a temporary setup.

hey dharmik i have a programming card but other than low cut-off setting change did you make any other changes in your quad


Subbu

I have set mine
low voltage cut-off
ni-mh
reduced power
switched between 8kH to 16kH(i don't see any difference in performance)

so i guess that there is a change in the specifications of the controller board

Control Board - https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=24723 (https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=24723)

i have also begun with the modifications required to mount the motors with the stock x mount by adding an extra piece of balsa to elevate the mount and fit the complete x mount


Subbu

it took 13 days but the biggest part of the quad has arrived from hk its the mammoth

4000mAh 3s 11.1V 30c Turnigy Lipo (i just paid 4$ for shipping and nothing else as i bought it using store credit  ;D ;D ;D ;D ;D)

do have a look at the pictures

Subbu

ps. the lcd kk2 multi rotor board was shipped yesterday and this time through hong kong post so should probably reach earlier

hi...subbu, how much u spend for ths full package...!!:)

the total price of the present configuration is 148.32$ about 8157.6 Rs EXCLUDING shipping (i chose ems for most parts and registered post for fc board and battery)

Subbu

there were concerns raised about the quad frame i got from hobbyking regarding vibrations and also the motor mounts had to be modified for mounting of motor and the motor mounts were not perfectly parallel to the ground. the first idea was to reinforce the frame with carbon fibre rods and that seemed to work pretty good but i wanted a sturdier frame.

so i went to the local plywood shop got  1.5' spars of 1cm thick plywood and the centre plates and motor mounts cut out of beautiful orange patterned acrylic sheets.

the total span of the quadcopter now is 940mm

(moderators could you kindly rename the topic to Quadcopter 940mm (HK multi-rotor board V3) Build Log)

a few pics have been attached

Subbu

That will be a sturdy frame :thumbsup:

thanks satyagupta for your advice regarding the hk frame i am feeling confident looking at the frame itself

You are always welcome buddy :) :) :thumbsup:

BTW whats the weight of the frame (just arms and mounting plates)??

hi guys the monsoon is finally doing some catching up this week, rains are much more frequent now. and the gloom has caught up with me too. feeling a lot lazy these days.

onto the update the frame is all done and motor mounts marked out for cutting and drilling tomorrow.

now onto the big question, i want to be realistic here the frame weight is about 600 -700 gms and the thrust at full throttle is about 0.632gms from each motor and i shall be using a 4000mAh 30c 11.1v turnigy lipo which is another monster, what do you guys think will it take off from the ground ?.

as i see it it should hover but not much altitude and flight time. i shall be going ahead with the present setup anyway since i am planning to use this frame as a platform for aerial photography. if needed (which i sincerely feel i will) i shall upgrade the power system.

i have used this motor with a 9x5 prop on my yak55 and it can make it go vertical. the yak with the new plywood frame restructuring weighs about 800 - 1000 gms with the battery so such performance makes me wonder about its performance on the quad if it shall succeed or not.

kindly let me know the pros and cons of this setup and how i could help manage its weight. also it being a 315W motor vibration may kill the stability of the quad too. i would like to have all experts on board onn this build.

the first pro which i shall add is the frame is super strong and very adaptable (and i really want to use this frame :))

i shall weigh in all the suggestions and proceed ahead (And literally weigh in all the parts on a scale too). attached are a couple of pictures

Subbu

it shall be unfair if i did not mention it here my friend HarshVardhan helped me a lot (and i mean a lot) during this and my hovercraft build for which i shall be ever grateful  :)

awesome frame bro :)  :salute: (:|~
good luck with the build ;;
gonna upgrade my quad pvc frames to aluminium frames . :giggle:

Yo bro good going, couple of things to help you out..

When you said:

Quoteframe weight is about 600 -700 gms and the thrust at full throttle is about 0.632gms

You mean 600-700 gms including electronics battery everything of just frame (arms and plates) no electronics mounted over it?? If it just frame then buddy you have to reduce a lot of weight (of the frame :giggle:) with my first build my frame weighted 600 grams just 4 x 1 feet aluminum arms and 2 x 5 mm plys and it was complete failure.. :(

I had to rework on the frame for the complete reduction of weight. Couple of advices to reduce frame weight,

Drill holes in your arms, remove unwanted portion of your plates.. that might help a lot..

Now lets talk about the thrust, you get 0.632 Kg ( i am sure you meant 0.632 Kg not 0.632 gms :giggle: ) so you get this at full throttle, so at full throttle your quad will get a total thrust of 600 gms x 4 that will be ~2.4 Kg which is not bad at all.

But here is what i have read a lot and got the same advice here on RCI too, your quad should lift of or hover at 1/3 rd throttle. i.e. if you throttle has complete 12 steps (as an example) after moving your throttle stick 4 steps your quad should lift of the ground.

Lets do some maths,
with 1/3rd throttle your motors will generate 1/3rd of the total thrust which is 600/3 = 200 gms
Now at 1/3rd throttle all motors will generate 200gm x 4 ie ~800 gms of thrust..

So the bottom line is your quad has to be less than 800 gms to make this work.. To begin with if you quad lifts off at 50% of throttle then that is also considered a good thing. But for hovering or aerial photography you need quad to lift off at 1/3 rd throttle. 

So we need to increase the thrust you can try with large prop 1047, even i started with 0905 props but faced problems with hovering my quad. But with 1047 props i get a very decent lift off at 1/3rd of the throttle. But then you have to buy new props, if you are not looking to buy new things until you get a decent flight (which i did) try to reduce weight of your quad.. Call me up if you have any issues ;)

Bro i am wondering how it reached to 700 grams with just 4 arms, 2 plates and 8 nut-bolts. I agree with satya bro, you will have to reduce weight to half atleast. I did quick calculations
4x 60grams motors = 240grams say 250
4x 25grams esc = 100 grams
1 x battery = 350 grams
other misc things = 200 grams
Total = 900grams + 700grams = 1600grams(excluding AP stuff)
If you see famous ht fpv frame used by justine(juz70), it has 350grams weight
http://www.hoverthings.com/htfpvblack.html

Bro carfon fiber.. they are very light and sturdy...

I have replaced my 5 mm plys used for plates with carbon fiber.

Even 1 mm thick CF plates looks very sturdy.. Very very hard to cut.. and some care to be taken while cutting

hi dharmik and satya so i have some breaking news ;D ;D

the frame weighs exactly 475 gms

and the complete electronics weigh exactly 745 gms

i just went to a nearby grocery store and weighed them in i am attaching some pictures too kindly note there was a zero error on the weighing machine of 40gms so i had to reduce it from the total weight

now i believe i just have to reduce the weight of the frame by a little bit to bring it to about 350 - 300 gms max which i can achieve by reduce the length of the arms of the quad by a few inches on each arm.

spoke to satyagupta and got come ideas on how to reduce the weight few ideas are to reduce arm length and cut off the centre plate excess parts

i also need landing gear ideas(more weight  :banghead: :banghead:)


Subbu

pic 1 frame only weight

pic 2 electronics only weight (battery fc board motors esc and even some male to male cables)

I think your target should be to get the weight to around 800-900 gms which i guess can be reduced by reducing the extra length of arms, drilling holes on them.

hi guys i got the replacement esc from gusty bhaiya today now all the electronics are ready to go

thanks gusty bhaiya

Subbu

ps my mtnl connection has stopped opening any websites due to some dns resolving error so using the background reliance modem

You are welcome subbu, would like to see it fly

so after working on it for 2 days i managed to bring the weight down to 272 gms but the arms are a bit flimsy so reverting to 1cm thickness arms with smaller length and holes in frame to reduce the weight further

Subbu

Good stuff.. frame looks good.. :thumbsup:

Motor - 4 X NTM Prop Drive 28-26 1000KV / 315W (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=21478 (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=21478))

I've been follwing the thread but it's the first time I'm seeing this. :banghead: . I've been eyeing these motors for my next quad. I'm eagerly waiting to replace my rather crappy dt700s ( hardly 130W) with the 315W NTM2826s. Please post the videos and any motor performance data after you finish. Thanks,

Vineet

Why bro?? why crappy?? ??? ??? have heard a lot of good reviews about it and highly recommended for quads... please share your experience dude it would help a lot (like me) who are planning to use DT700 or DT750 for their quad..

Quote from: satyagupta on July 04, 2012, 08:27:54 AM
Why bro?? why crappy?? ??? ???

It's absolutely my personal opinion. I had bought them because they were being hailed as the verymotors for quads.
Although thier performance is fine, I feel their build quality is not. As far as build (and build quality) is concerned, I think multirotor motors should have a short shaft and long wires. Longer the shaft, more the vibrations. Althogh the shaft can be cut, I need dremel for that. Perhaps, nowadays, these features are becoming characteristic features of multirotor motors. And the mount too. The holes are located in a triangular arrangement, and most of us prefer two-hole mounting for quads. (atleast I do) So the holes cannot be perfectly linear while mounting. Considerign this, I feel x-mounts are better.
Consider all these, I think parkflyer-type motors are better, like the NTM2826 1000kv. (pikle6 aka Subbu uses them on his quad). I'm waiting for more reviews on that motor.

But it seems I'm the only not satisfied with dt700/750s. There should be a reason why everyone likes them. I'm still searching for that. :)
Also, I think my frame is also crappy (at 400+ grams), so I'm rebuilding it with lighter fiberglass and 2channel aluminium.

Offtopic, but this may be useful.  I realized that my home DSL connection from BSNL was acting up.  A little looking around proved that the connection was there and it was fast, only the DNS servers used by BSNL were overloaded.  Browsing anything by IP was instantaneous.  So I reconfigured my DSL modem/router to use OpenDNS's DNS servers, but they were also acting up from time to time (not sure if this was BSNL interfering, or if OpenDNS itself had issues).  A little more reading proved that our friendly neighborhood "Do No Evil" company (Google) was providing DNS service, and their servers were very fast.  So if you are having DNS issues, please try these 8.8.8.8 and 8.8.4.4.  That is, if you are willing to trust Google... the big brother ;)

finally finished the frame going with the 10mm thickness ply arms will go ahead and reduce the weight from the frame after i put on the electronics now.

some pics i know the frame is a bit overweight but i will find some way to reduce its weight further since i cannot reuce the thickness of the arms anymore or else the become very flimsy


Subbu

so the motors are mounted, escs connected, fc board battery and rx all ready to roll but then i remember of the battery harness for the esc's and battery just working on it right now should be done in an hour.

sea trials begin (hopefully) tomorrow  ;) :)

Subbu

great let us know the the test flight results... :thumbsup: all the best

All the best Subbu, great effort!!  {:)}

Pikle bro have you tried KK2.0? I heard auto-level is bit tricky to tune in this version.

hey dharmik yes you can either change the p and i gain values in the self leveling menu or you just keep calibrating the sensors (its automatic) until you get a true zero point

that however is out of the question since my arms vibrate like hell when i power them on i desperately need better mounting ideas for mounting a motor with a downwards protruding shaft onto a plywood arm please help


Subbu

I think your frame is fine but this board is very sensitive to vibrations.

dharmik i never even mounted the kk2 board yet so no problem with the sensitivity there

the static full throttle rpm without props generates a lot of vibrations all transmitted to the central plate with refrain me from mounting the board without solving the motor vibrations issue please suggest some way i could get rid of them should i use aluminium arms or any other suggestion would be helpful

Subbu

I am using cricket bat grip and it works perfectly. No more vibration issue.

a few minutes ago satyagupta suggested on the phone that i try spooling all the motors up instead of one through the k22 board and guess what happened

at full throttle the quad became almost vibration free (i dont know the reason why but i believe it could be due to all the vibrations cancelling out each other) and that was the sweetest moment in the whole build log till now.

dont worry guys i got the photos and the video of it starting up and working superbly ( on the ground  ;D )

i just made a makeshift battery harness with polycab wires and local screw on connectors and it worked great but i am going to replace them preferably before the first flight.

viewer discretion is advised since the initial prototype of the quad without proper wiring may scare you but the performance will more than suffice for the flaw.

and finally the quad as of now weighs exactly 1076 gms - AUW

video is being uploaded might take some time but it will be done today, and so tomorrow the sea trials can successfully begin  

Subbu

As i had said before :) alls good now :) waiting for your maiden flight :D

i almost forgot about the landing gear guys i am using simple foam blocks as landing gears on this one to begin with and later with upgrades like motors and frame i will go for a better landing gear. will post some pictures tomorrow. and satya maiden will probably happen on monday.

as of now its time to enjoy the video with exquisite music from john mayer - 'GRAVITY'

the first line of this song goes like this - Gravity, its working against me - now i have felt similar when my planes have crashed  ;) :) (how about you guys)

anyway enjoy the video (anwar bhaiya is there a way to embed videos in their original aspect ratio)


Subbu

Sorry for the bump guys, but I have a doubt about these NTM 2826 motors.

I received mine yesterday and I see that the bolt-on prop adapter fits on the opposite side of the shaft and the mount fits on the lower portion of the motor (as it should be). So I have a prop adapter facing upwards and a mount on the lower part of the motor, BUT the shaft is facing down too!?!? I know it is the prop adapter where I'll be connecting the props, but there's a long shaft spinning below the motor? ???

yes... bro i know that, and i really hate that but thats how it comes :( you have to drill hole in your motor mount. Or you can change the shaft direction if you want, you have ordered accessories then you would have got the other shaft along with it. :headscratch:

Hmm, may be they've designed the motor with the shaft protruding outwards to reduce vibes.. :scratchhead: But I like these better than my older motors.
yeah, I've ordered an accessory pack, but no extra shafts.

How do I change the shaft direction?

To change shaft direction (usually) you have to remove any c-clips on the motor shaft, loose two hex screw on the motor bell which hold the shaft, then use a hammer to tap the shaft out through the other side.

Thanks a lot. I'll give it a try. :)

Ya thats how its done, just be careful with e-clips i had a hard time putting them back :(

Yeah, they seem to be very delicate and small. Or I guess I'll leave it the way it is. ;)

Thats what i did :giggle:

Rajibic you have to connect aux input of the KK2.0 board to radio channel on which you have switch, To calibrate your board read the instructions that is provided in the board itself.

so i hv to connect aux of control board with receiver.then

Yes... but to the channel which has switch (ON-OFF types)

hw do i knw which channel has on off types

test it, first 4 are the AIL,ELE,THR and RUDDER rest of the channels should be it. Besides there is a receiver test option in board as well, you can use that to test which channel is responding to switch..

Which radio you are using?

FLYSKY 6CH

I guess both channel 5 and 6 have switch so try any one of them :)

Here it is
http://rcsci.blogspot.in/2012/07/kk20-accelerometer-aux-channel-setup.html

Ok so after all the frames and the control boards this is what it has come to. the following are the final specifications i intend to use

Frame - talon v2
Motors - 4 x DT750
sc - 4 x HK SS 25-30A (gusty bhaiya thanks for the esc  :) )
Battery - 2200 / 4000 mAh 3s 25c turniny lipo
Control board - KK2 Multirotor board
HK power distribution board
Props- 11x4.7 (still need to get these (Sujit bhaiya do you have any extra spare props from your quad)  ) (any local source is welcome too)

I had one question in mind I wanted to increase the length of the wire's on esc going to the motors, now I know that using the Silicon wire is recommended but it is hard to find here nearby so can I use the normal copper wire which is available locally (of similar gauge) provided I get a good enough joint. So once that problem is solved I guess then I shall be ready to roll.

Attached are a few pictures of the quad as of tonight

Subbu

I have both 11x4.7 props and 16AWG silicone wires .... no issues

thanks sujit bhaiya can i come over and collect it tomorrow morning or evening


Subbu

finally got the time to edit and upload my quad's flight video. i guess that sums up the rather discontinous build log here. do watch in 1080p HD.
:) :)
