Title: QUADCOPTER MOTORS SPINNING UNEVENLY Post by: harsha on August 20, 2012, 03:16:02 PM Hello,
Im building a quadcopter.I had built a frame with aluminium square channels and using HK V2 Board.I calibrated all the esc's individually first and then calibrated them connected to the control board keeping the yaw pot to minimum.But when i tried to give the throttle initially only one motor spins and then the other motor.I had tried different firmwares (4.7,2.5 etc).I also tried another method,when i started to increase the throttle suddenly all the four motors spin.A part from this issue every thing is working fine.How can get the four motors to spin evenly at the same throttle??

(b) if the problem persists interchange the motors, try different config (X to + and vice versa), if no joy (c) change esc PS which radio are you using, is you norm, reverse correct for your radio and throttle trim to zero ? recheck Title: Re: QUADCOPTER MOTORS SPINNING UNEVENLY Post by: satyagupta on August 21, 2012, 11:48:07 AM HK SS are not so good with multirotors bro with so less programming options :( I have used HK SS and faced many issues and one was very much same that you are facing now, motors not starting together or spinning in different speed. And i had to change to HK blue series ESC which are one of the best for multirotors.
Still if you can try what gutsy sir have suggested you cause with HK SS i was able to fly my quad once but had lots of glitches in it, motor would not spin in sync. The thing that you need now is throttle calibration of ESC to fix this issue and that is missing from HK SS ESC :( Title: Re: QUADCOPTER MOTORS SPINNING UNEVENLY Post by: harsha on August 22, 2012, 04:52:17 PM Im using a Fly sky 9ch Radio sir.Ya i have to try the steps that you suggested be.will try my luck :). Thank you

I am facing the same problem as you. Have you solved it. Title: Re: QUADCOPTER MOTORS SPINNING UNEVENLY Post by: harsha on December 15, 2012, 03:53:57 PM no i did not get it solved.But as far as i know the possible solution for this problem is replacing the ESC's. Even i did not replace the ESC's yet because i dont have the funds and time too.But keep trying,don't loose your hope. Another way is that get a programming cad for the ESC,it will be useful in the further models too.
