When I finished my trainer and was ready to fly (lol) I took it to the field on trainer night and had the club trainers give it the once over. I did have several things wrong with it. I took it home and made the adjustments. Next time out the club trainer starts it up checks the engine, tunes it, checks the radio, range test.
Looks good so he took it up. Then he got me on the buddy box and it flew great.
It will be fine.

Good Luck
Bill
