RE: Questions
I agree with most everything Don just said, except that I always charge the plane and transmitter for at least 12 hours (with the wall-wart charger) the night before I'm going flying.
As for the O.S. 46 AX, they are about the best you can get for being easy to set-up and get broke-in. I always recommend O.S. for new flyers. Follow the instructions and/or have an expert set it up, run a tank of fuel through it, and you should be ready to fly!
Good luck!
