Hey Guys I have a cap 21 with 83" wing span this plane is huge the more I read about the cap 21 being hard to fly and the bad tip stall the more I think I should try to install flaps can anyone tell me how? how much of the ailerons I should keep can I just cut the aileron and install servos for flaps they are ca hinges now so it would be fairly easy to just cut off and build any suggestions would be very helpfull thanks Mike ! Ps anything at all you can tell me about this cap 21 would be very cool [8D] Oh I'm going with a sachs 3.7 what do you guys think about that [:-]
