RE: BEGINNER PATTERN PLANE FOR A YS 140 SPORT
I fly the Inspire-90 with a Saito-125. The only problem I have sofar is getting the CG forward enough. I guess with a YS140, you should not have this problem.....
Sofar the frame is holding up very well, then again I build my ARFs with care. I have about 60 flights on it sofar.
