RE: trainer
Sportster,
If your "friend" doesn't already fly RC, then I'd highly recommend that you find a local club and an instructor.
These things are much harder to fly than you may think, and trying it on your own usually results in a 10 second "flight" followed by a pile of sticks.
You might get away with it if you've had dozens of hours on an RC simulator, or flown a lot of electrics, otherwise you're chances are greatly reduced.
Good luck,
Dennis-
