The Avistar is considered a trainer by my club. It is far and away the most popular trainer used. Yes, it has more aerobatic ability than most trainer type planes, and is considered an advanced trainer, but I am surprised that your club would not accept it. Are you sure?

BTW, you may want to consider the Horizon Hobby Alpha trainer with the Evolution engine. It's very easy.

However, at some point if you progress in this hobby, you will most likely need to build some sort of ARF as a next step. If you go this route, some excellent trainers to consider are the SIG Kadet LT40, Goldberg Eagle, Midwest Aerostar, and the Global Hobbies RCM trainer. The last one is especially fast and easy to build, and comes with a decent engine in a frequently offered combo package.

Good luck!
