Finally got some good flying weather, both friday and saturday, and the pitts and other things went into the air. Had some flying with 2xpitts flying around each other as well - check out the video:
Both pitts have upgraded motors, giving around 300 watts with 11x4.7 propellers. Endurance is not a problem if you want to fly slow - the other guy flied his over 20 minutes on a 2200mah battery.
The other pitts almost met an early death, but the loop did end over the gravel and not in it, so that was ok :-) It was a close call though.
