Hey guys, I took your advice and bought a Trainer. I ordered 2 of them today, one for me and the other for my wife. Tower Hobbies has a deal going on 2 for $98. they are .40 size kits, and I ordered all the accessories required to build 1 plane, wheel collars, covering, ca hinges etc. I need to get an engine and radio.. any suggestions?? It calls for a .40 - .46 2 stroke or a .52 4 stroke, is there any certain radio that I should get or just a cheap 4channel?
