Did anyone mentioned that "this is not going to be cheap?"

Remember that you'll badly want at least one ( or more ) spare set of batteries, so you can charge them while you are flying from another pack.

I agree with -pkh-'s advice.

Start with a smaller plane and work your way up. That way you'll learn the intricacies of EP's while using less expensive planes and components, etc.

You'll also be in better shape to decide how you want to support your larger scale EP "habit"...
