about the gear box that is good to take the thurstmaster or the kyosho magentic mayhem motor. i was told it should be GD600 3.0:1
but the one i could find at the local hobby shop was 2.5:1, should i buy that one and change the pinion to 3.0:1? or how does it work?
would 2.5:1 be enough for the magnetic mayhem motor if im using 8 cells?

also,that set up takes a 12x8 properller,should it be the folding properller so that it will not touch the floor or should i extend the landing gear for a non folding 12x8prop. i dont wana have to raise the landing gear .thanks in advance
