Overall very stable and easy to fly. Have only flown with partial throttle, yet to try full speed due to the propeller collet adapter being loose from the factory. Learned that the two screws that hold the propeller down [rubber band] needed to be tightened. Looks and sounds amazing.
I started with the 3rd hole on the wing servo and the outer most hole on the control horn, which was very tame. Plane will work with both 2 or 3 Cell lipos; but of course 3S for the most power!
