The parts that will take the longest to arrive are the Hobby King RC components from China. I made a list of parts I like, and optional parts that are acceptable. Then I was careful to only order parts that were in stock. If there is a specific part you're set on using (thats temporarily out of stock), where you don't want to spec an optional component, make that part a separate order. That way, HK won't hold back the rest of the parts waiting several weeks for the shorted part to arrive before shipping everything. After performance testing results, I may end up wishing I'd used a different component than some of these, but here's whats on its way from China to get me started...(the charger requires a power supply, they can usually be purchased locally with an input from house current, or, automobile socket for RC charging in the field, or both)

You can get the drawn cup roller type in clutch only or clutch bearings. The ones linked to above have a set of roller bearings either side of the clutch mech.
How are you going to attach the motor to the shaft? If you need an ev warrior shaft with the notches in it let me know and IÂ´ll send you one.
