The problem is that most trainers are fuel, not electric. The basic concept of a trainer is large high wing, large dihedral, and slow speed. Another serious consideration is that the plane has to be fairly tough. It will get beat up pretty good by most students. Electrics are very light, by design, and therefore usually fairly fragile. They won't stand up to hard landings.

You may be better off finding a good, inexpensive rugged trainer that uses a, oh, 40 sized fuel engine, and learn with that saving your electric desires for after you learn to fly and land without having to worry about destroying the landing gear, underside, and so on, of an electric aircraft. There are lots of forum threads on suggestions for beginner aircraft so I won't go into that, just read up on RCU and see what is recommended, then either hit the on-line sites (Tower Hobbies, Horizon Hobby, and so on) or to your local hobby shop, and get something that you can rely on as being strong enough for a trainer.

And, as someone already said, solicit the aid of a qualified instructor with a buddy box. We keep repeating that.. a qualified instructor and a buddy box!!!! This alone will save you a lot of money no matter what you plan on using as a trainer.
