G'day Mate,
NO a Piper Cub of any sort is NOT a good trainer.
Try the Seagul/Pheonix, Boomerang 40, it will cost about $89.00 from Roj's hobbies in Melbourne, see here, http://www.rojshobbies.com/Planes.html
They are a great trainer, put an OS 46AX on it, swinging an 11x6 prop, & whatever radio you have, if you don't have a radio, I can recommend the Spektrum DX7.
Another very good trainer, that's available here in AUS, is the Skyraider Mk 1. same engine & same radio.
