Hi Mugenb.
Not neccessarely planes motors are torque and not RPM. It is depend of aplication-for airbatic you realy want to torq and you don't want to engine start winding up, for Pilon racing-they want to have winding engine.
Please send me pics of our crank and sleeve, I might be able to suggest something by looking on the pics. You can post them here as well, I hope nobody will be affended by those pics

. I am not familiar with COMO S 40 motor, will look on the net, may be can find some info on them. But pics defenetly will be helpfull.
