I bolted the prop on and tested it on the ground last night.
I let the motor warm up to 150 degrees and then ran through several cycles of idle/max power, holding the throttle open as long as I could handle the thrust.
Afterwords I inspected the repair and paint and could not see any change in the prop, so I’m calling it a success. I hope to test it in the air this weekend but weather is not looking good.
Sidenote: I do appreciate the concern of the few people who freaked out at the thought of repairing a prop. Remember this is a paramotor, we don’t see near the mechanical stresses on propellers that GA aircraft do. That’s why guys have been successfully repairing their own equipment for decades.
