I am having an electronics problem, perhaps someone can lend a helping hand.
First allow me to describe the problem, and then I will explain my setup. I am having a motor issue where the rpm of one motor seems to surge... I have noticed this and my last airframe of the twins.
If you listen on this video you will hear the motors surging. It is a continual thing rpm's drop and the rise again and again. This is on one motor only...
Throttles come out of the throttle channel into a y cable to the two HK 10A ESC's. I have lifted the power wire from one of the esc cables so to not overload the receiver. No V-tail for differential thrust on this so far. The one thing that I have noticed is that this happens when I run my 20c 800 mah 3s through it. If I run with a 15c it doesn't do it. Anyone have any ideas?
