If you go for the Tower Trainer 40 RTF package you will get the plane, engine, and radio for one price. The price for this package is $279, and if you check on Tower's site you can usually get $20-$30 off your purchase. I've trained many students on this plane and I personally think it's one of the best bargains out there for learning to fly.
