Check before flight
I can't tell you the number of crashes, I've seen or heard about, that could have been avoided if a simple control throw check before flight had been accomplished. Today a maiden flight didn't go so well. Ailerons were reversed.
take the time to stand behind your airplane and say to yourself aileron up in the direction I move the stick. Then it's elevator up with stick back. Elevator down with stick forward. Finally rudder moves in the direction of the stick.
Please do this before your first flight of the day. It'll save you an airplane some day
