Instant Prop Shaft Adapter

Many of us have reamed out prop hubs and then wanted to place the prop onto a shaft that is too skinny to center the prop. A quick fix for both glow and electric airplanes is to tightly wind electrical tape around the prop shaft until it properly centers the prop. Then cut off the excess length with a single-edge razor. The prop nut will hold the now-centered prop tightly against the adapter back plate—problem solved.
