RE: Need help!!
I don't see how going electric is going to make the plane any eaiser to fly. I would suggest getting an instructor and learinging how to fly. Any of the clubs would be happy to teach you. You would need to join the club most likely, at least at our club you need to be a member for insurance purposes.
As for 40 size trainers, any of them are OK and any of them can be converted to electric. Some come in ARF form electric ready. Sig, has a couple good trainers. There are quite a few others also. Take a look at the list of recomend trainers in the beginers fourm.
