Hey Guys,
I have built a few setups with WKM and my own 900mm frame with success. This time, I want a lighter setup and change motors from Hacker to Avroto 3520 400KV with 17" carbon fiber props.
I notice when I plug in the battery, sounds like 3 of the motor armed first and then follows with the other 3. Then in my test fly, the whole craft seem to pulsating up and down and sounded like motors are powering up and down rapidly. Sounded like timing is off. It doesn't seem to be the same behavior as gain too high.
Anyone have any idea what might be the issues, or have similar scenarios?
