I'm starting to get into full scale airplanes (getting my private pilots license), and every little detail is on preflight. Of course, your not watching it fly from the ground, your flying it in the air, so you want to be cautious.

Anyway, I check my RC planes like I check the full scale during preflight.

Pre flight can save all your airplanes, and save you from taking home pieces at the end of the day. You never know, landing gear screws, engine mount screws, servo screws, anything, could have came loose during the last flight, then the next flight goes bad.
