rchead7, You lost me in there bud.

Check out this picture of how I converted a 1.20 size ARF to 8S electric.
I held the motor in place in the cowl to get the right distance. Then cut square wood dowel to the right length and drilled it down the middle. I then used all thread (10/32 here in the US), lockwashers and nuts to make my own, custom length spacers. That motor is over 3HP, spinning a 17x10 prop and it held fine.
