With Ardupirates code my quad had lots of thrust available to carry camera. It was unstable if giving full thrust, so I had to turn down the thrust to about 75% by adjusting throttle Endpoint(EPA) on my transmitter.
With AC2.0.46 my quad just barely manages to lift the camera. I have 100% EPA on transmitter, and have calibrated the ESC's. Is the throttle being reduced by the code to make sure the quad have enough power to handle correctly? Is there any way to change this? I just need a LITTLE more power.. :-)
