I am only going to be flying park flyers for a long time, most with the same engine, spiner, prop: so what i think is:

I have two planes, both park flyers.
I have the servoes in, and i don't ever take them out.
Also, the engine stays in all the time.
But.. at the field, if i have both my planes, i fly one, and then take out the riecever/esc, and put it in the other plane, in less than 10 minets.

Right![]
