It's a great crime that there is no good Stik kit available. Though it/they are as easy a model to scratch build from plans as ever there was.

I had a G.P. Big Stik converted to a tail dragger and it was (IMHO) an ideal second plane. Had very good slow speed characteristics and was agile but predictable. Lost mine to a mid-air. Only one I've ever had. :-( My wife always had hated the iron crosses and offerred to replace it if she could approve the model on looks. Worked for me.

Another good choice would be the Kangke SK-50. I had a Super Tigre (how come they spell "super" right but "tiger" wrong? ) .51 in that one (I actually flew 4 different engine makes and sizes in her over several years) and that also was a good choice for #2. Be cautious of the "cheap" Chinese Kangke engines (again IMHO - mine was a loser until I changed to a Perry carb that cost 60% as much as the engine had - though it's a trooper since then).
