RE: Graupner J-3 piper cub??
wise advise you have been given. the cub and in general any "true to scale" aircraft are a bit more touchy to fly. great fun and look awsome but not for the first timer. my suggestions would be to get the hobbico nextstar or the rcm trainer 40 with an os 46 ax both are excellent trainers. but of course there are many many trainers available the avistar would be another good one.
