EC1500 and Esprit Prop Shaft Adapter 5 mm x M8

The Esprit Prop Shaft Adapter is about 30 % bigger than the stock unit so you can put more torque on the nut and threads. This translates so about 30% more gripping power between the aluminum collet and steel 5 mm motor shaft. In Jason Ms video he recommends holding the spinner backplate or motor to keep the threaded adaptor from turning. This is done with one hand while the other hand uses a wrench to tighten the nut.

I made up a tool that slips into one of the 4 motor cooling slots and this keeps the motor/shaft from turning while the collet is being tightened onto the shaft. Its a steel 6 mending bar that I cut with a hacksaw and filed down to fit the slot. Its bent into an S shape to fit between the prop and plastic nacelle. The nacelle is cut out for clearance.
