Nice choice,
double and triple check everything,Make sure your throws and balance are correct, make sure all flight controls are moving in the correct direction, make sure your batteries are fully charged, do a range check of your radio with the engine running.It wouldn't hurt to run a tank through the engine on the ground before taking to the skies.If possible have someone standing by (hopefully with some experience) to help make trim adjustments.
What was your first plane and how much experience do you have flying?
