I've just been outside flying my recently rebuilt arducopter. I've added a lot of extras like FPV, OSD and LEDS. This has led me to cable tie the video transmitter and osd board onto different arms. I was worried that this might introduce some stability issues in terms of center of gravity, and initially it was a bit rocky, but after using auto trim it seems to be flying very well.
My one big issue is with my yaw. It is extremely sluggish to respond. I previously flew in + mode and found yaw to be very responsive. I am now flying in X mode with the most recent version of the Arducopter code. Dose anyone have any tips on how I might resolve this ? Do I need to start tuning PID's ?
