I have a bit of a problem with my tricopter. When I max the yaw when flying it doesn't spin nicely on the spot like most multiwii tricopters do but it circles around in ever more wider circles. Like you see in this video I made earlier today:
I made a new setup now. The gyro chip is now exactly on top of the nunchuck chip, and exactly 37.5cm from all motor axles. So that should cover the gyro and nunchuck placement. Now the weight is still quite off due to the camera in front. I've blown an ESC so I can't test it yet. I'll keep the forum updated on the progress.
