Hi everyone
I need help or advice on what starter plane I need to buy. My brother went to work in a different state about 2 years ago, and he left me a brand new RC plane he built up himself. I would love to fly and have been wanting to get in the hobby for a number of years now, but never really knew where to start. I am not completely new to RC, I have had a few nitro trucks, so not a total beginner. I have a flight simulator in which I have put quite a few hours on.

The plane my brother left is is a Great Planes Extra 300s It's got a 50cc gas engine (not nitro) (not really sure, but thats what my bro said it was) it's complete with all the servo's and radio. It has never been flown, nor is it aligned or balanced....not sure how to do that. I have a Futaba
T9CAP remote for it.

So here's the real question...

What trainer plane would you recommend I buy, to get the experience I need to fly this plane?
