I have an added safety procedure that should be done first. TX on first....turn on plane... and then move a control surface to verify. Now..set that throttle to your start position!
This may sound elementary, but believe me, MANY accidents have happened because the radio and plane was off. I had a guy watch me like a hawk when I would start my plane. He "pressured" me to learn this habit. Well guess what? Yesterday I was careless and left my plane/tx off and started at almost full throttle. Thank God for my goal post restraint!!! I made this aluminum fold down goal post restraint about a year ago. It saved my bacon yesterday! As most all have said: start on the ground and use a restraint of some kind!!! ..... lownslo......

PS.. Not in the picture is the long 1/4" dia. rod that is the positive locking device that goes through both sides.
