1) Buy plenty of extra props! Because you will crash!
2) You don't want to 'fly' the plane. you just want to adjust its trajectory to one that you like.
3) Don't move the sticks very much. You only need to gently nudge the plane in the direction you want it to go in.
4) Probably over repeated but launch and land into the wind.
5) Have a pre-flight check list because you will forget something like to reverse a servo or your center of gravity will be too far back or something like that.
6) As always, Have fun
! You will learn to deal and learn from crashing. Plus, foam board is cheap so wreck it all you want.
I'm sure there's some stuff I missed but hopefully someone else will fill in my blanks.
