You can. I'm using servo leads without any problem. Shielded would be better though, but most cameras and video transmitters are delivered without.

I have a flying wing with this software. Balanced prop, lpf on 20hz, default gyro smoothing, pitch P on 1.8 and TPA on 0.9. And I still get oscillations on high speed for acro and level.

Any ideas? Could I get the Ps from other flying wing owners?

Tnb2, if I hear about a plastic frame and strange behaviour with stock parameters, I think of only one thing. Vibrations! Balance props/motors and use a low pass filter of 42hz or 20hz. Then you should be fine. I fixed multiple quads that way.

Re: SW Development on Minim Osd

The RC-Timer has a switching regulator and should not have the overheating problem. It is not possible to do the 5v mod on the RC-Timer model AFAIK.

BUT my rctimer did burn within the hour. I got a new one from them for free, been testing it and seems OK. Have not dared to fly with it yet.

Re: multiwii 2.2 elevator and aileron flip

Because if you trim in acro, it will see input in level. Then you are trying to correct that with acc trim, in horizon it could even be more strange. So, it is ok if you only use acro. If your copter is not in balance, it will always need to correct that different in 2 directions. That gives problem...

And check on your transmitter that the switch does not something else too. Do you have a channel monitor on your transmitter to check it?
You should not trim your quad in acro by the way. If that is needed the center of gravity is not in the right place or the speed controllers need calibration.
