To help me from destroying a plane I like to set all my planes up the same way, (all the same channels either normal or reversed on all planes)
When I finish the maiden and trim flights, I set all my trims to center and adjust the surfaces for trim. This way if I do have the wrong model selected
I won't have any problems with controls reversed, and the trims will not be all over the place. I also preflight before every engine start and recheck
either on the line or if someone is carrying out for me I check while they are walking.

But we all make mistakes and accidents happen.
