Title: Home made quadcopter - need help Post by: niteenk on September 27, 2015, 03:40:53 PM Hi All !
I have tried making quad frame myself and mounted a2213 motors with 30a esc on it I am using kk2.1.5 having firmware 1.6 installed on it. Using thermocol blocks as landing gear. AUW is 1kg (using 5000 mah turnigy 3s lipo) Issue is - it does not lift or whenever it lifts tilt to one side even after enabling self level ON I dont know if A2212 1000kv brushless motors is capable of lifting 1 kg weight. also Not sure if props are balanced yet to check it Please let me know if you need any more details.

You should follow the instructions given in below video for kk board setup https://www.youtube.com/watch?v=8NAXSBCtSLY (https://www.youtube.com/watch?v=8NAXSBCtSLY) as well as 4motor of 1000kv is capable of lifting weight of 1kg mostly I think the issue is in esc calibration , PID or acceleration calibration follow instructions in video and do share your video Happy Flying Ragards Sumit Ambre Dream Innovation www.dreaminnovation.co.in Title: Re: Post by: niteenk on September 27, 2015, 09:14:49 PM Yes sir, i will try it

Finally I managed to get my quadcopter up in air. Here is maiden - Try 1 video (bit harsh on landing :banghead: >:D https://www.youtube.com/watch?v=Mvc8i9jDhSw (https://www.youtube.com/watch?v=Mvc8i9jDhSw) Title: Re: Post by: niteenk on October 03, 2015, 11:58:08 AM Any suggestions how can i improve its stability?

Congrats on successful maiden. Setup seems fine. You could try increasing the expo on aileron and elevator to reduce initial sensitivity. Title: Re: Home made quadcopter - need help Post by: SK1701 on October 04, 2015, 10:58:43 AM Congrats on your maiden flight :thumbsup:
As Iyer sir said, try adding a little expo to smoothen roll and pitch. I would also suggest you program a throttle curve that is less sensitive around mid-stick. If you tell us which radio you have, someone might be able to guide you. I would also suggest you upgrade your kk 2.1 to the latest firmware, either RC911 (http://www.rcgroups.com/forums/member.php?u=432613) (my preference) or Steveis (http://www.rcgroups.com/forums/showthread.php?t=2298292). You can flash the kk with either a USBasp tool or an Arduino. Another important thing to do is PI tuning. I found this (http://oddcopter.com/2013/01/06/easy-diy-quadcopter-build-part-4-tuning/) guide very helpful. Make sure to tune the quad in acro mode first and then tune the self-level P values.

I am using Flysky th9 radio with stock module. I am still learning radio various radio configurations and its effect on flight. I will definitely go through guide which you have provided. |
