I really think that the direct to diff outrunner setup could do with some sort of slipper arrangement. I was thinking to use a revo slipper on each end of the motor. Where the spur is normally mounted, a plate with standoffs and some sort of adapter to mount a drive cup could be substituted. This would require shorted center driveshafts. Not sure if this would be feasible, but it is all I can come up with.

Here is an idea that will really annoy the electric diehards!!!

Why not make the center shaft of the outrunner capable of mounting a nitro clutch on either end? That would create a mechanical disconnet, and cure the startup cogging problem. Mechanical brakes would also have to be employed though, raising the complexity a notch.

Plus I have no idea how big the diameter the nose of a nito engine crank is. It would have to be smaller than 5mm to allow the shaft to plass thru the bearing, etc, in the outrunner. Bigger outrunners use the 6mm shaft, so maybe it would work.

I only throw this idea out cause the cluch adapter on my revo really makes the motor work smoothly. I have no idea if the nitro cluch would be strong enough to handle the power and torque of the outrunner.
