This is a STL CAD model of the propeller for FMS 980mm P40 RC Airplane. I tried to make it as cool as possible, from testing the performance has been similar to the default propeller. This propeller can serve as a cheaper alternative to the FMS propellers, which cost around $7-$13. Each model can be printed with %15-25 INFILL. HOWEVER, THE LOWER THE INFILL, THE MORE LIKELY IT IS TO SHUTTER IF PROP STRIKE OCCURS. Please use this propeller at your own risk. Enjoy cheaper propellers.
