RE: Tower hobbies Trainer
Think positive. If you get an instructor to help you out, with a buddy box, your chances of a crash are minimal.
You have a great setup there. My first trainer was the Tower 40 ARF which I later sold and changed over to the Hobbico NexSTAR and solo'ed with that. The Tower was a great flyer, and still is, by the way, with the Tower 46 engine.
