Replacement R/C Propeller

This is a propeller for an R/C boat, I made one for clockwise and counter clockwise as my daughters RC boat needed one of each. Seems a bit faster than the original cheap two blade propellers that which didn't have much surface area, so that's a nice benefit.

I undersized the hole a bit to ensure it would hold tight. To assemble, I heated the shaft of the motor a bit with a lighter and pushed it on straight, very snug fit and does not slip.
