Having no experience with electrics I do not have an opinion on the electric suggestions.

Two things I would ad:

Check with the local club and see what they suggest. I know electrics are very popular, but no one at my club is into electrics and the help we could give would be limited. Purchase the brand radio equipment that others in the area are using. Someone may be willing to provide a transmitter to use as a buddy box, and being able to borrow other small items such as servo arms is a plus.

Consider purchasing a used trainer. Many hobby shops sell planes on consignment. Several buddies have found 40 size trainers in great shape, complete with engine and radio for around $250.
