a while back i had a gp .40 cub arf, supertigre .40 ringed for a motor-over powered, flew well at half throttle ( more scale like ). well anyway that plane handled alot different in the air and when landing than my Sig lt 40- converted to a taildragger with a supertiger .61 ringed. looks cool with wheel pants and two tone covering. the .cub didn't self recover at all, but was not at all hard to fly. the problem was with landing it - it didn't want to quit flying! with a cross wind, you did have to cross couple the controls, which can be hard for a beginer. for pete's sake don't, waste your time building a cub- buy an arf to bang up!
