Mark, I have an extra RX8 trigger wheel
and my next door hangar neighbor is making a hub
for it as we speak.

I will try to find a better motor as the shaft
diameter on that one is a bit marginal IMHO.

OK I found one. I'll order one tomorrow.

I have a variable voltage power supply that is perfect.

I'll make two hubs. 1/4 inch shaft.
