RE: Goldberg Skylark 56 ARF versus Tower Kaos 40 ARF
I've been flying the Skylark ARF for a few months now. It's biggest shortcoming is the lack of rudder authority for stall turns, other than that it flies the pattern very well and would do well in sportsman. Mine is powered by a Tower 46 and the airframe really moves out. Spins and snaps are very easy to do, no problem there! I wouldn't consider the ARF version of the Skylark an advanced trainer/beginner trainer. To me it's an equal to the Kaos ARF.
