RE: Rudder wont work
I've watched my father (who has been flying for over 20 years [at-the-time, since then quick the club]) crash a J3 Cub and other such planes, and he was a certified member of the air club - a PROFESSIONAL.
With my father being a professional and crashing these types of planes, there is no way a beginner can fly them . . . . . I strongly suggest you do not get one as a first plane . . . . and get a TRAINER
Just my opinion!!!!
