RE: Big Stuka ARF
If set up right, the BH flies very well. I had my CoG a little too far back which induced unpredictable pitching, particularly with full flap. Once the CoG is right, and the aerolins and flaps properly aligned to the wing pitch, it flies hands-off, even on landing approaches. However, definitely not a trainer, because you must keep your eyes on it all the time (eg let it start getting out of shape and it will do its best to suicide).
