Really dumb Newbie questions.....

On fuel: The engine is broken in right? You don't want to run Syn in a fresh motor (R/C or real).
If the motor is stuck in the bird. Get it out! If this is used you probably should pull it and check the clutch, etc. Take the pain on the muff now rather than later.
Make sure to have a heli-bud check it out before you try to fly it. The last thing you want is a messed-up heli setup coming at you like a food processor on drugs.
In that vane: Make sure all of the rods are correct length and radio moves to the right pitch etc. I got a "new" one where one of the swash rods was 6mm off from the other side. It would have been on its top before I could even thing if I had tried to fly it that way.
Good luck and be carefull!
