I set up my first plane with pull out for off. Thinking that if the switch button bumped something like my leg, the radio remains on. But when not flying you have to make sure it's pulled out so that it will be off and not discharge your battery. I actually made a guard that would hook on and keep it pulled out while transporting and being at home. I'm sure there maybe others who might want it the other way around. Now I just prefer to mount the switch right through the fuselage side opposite the muffler with the slide switch on when slid to the rear. Same philosophy if it should possibly brush up against something, it will be on.
