This 5″ propeller can really move air!

You can make a fan from your motor.

In our experiments we mounted one of the motors on the piece of styrofoam and this propeller provided enough airflow to move this “boat” across the spa.

Unfortunately all of our motors are too heavy to be used in airplanes.

Propeller could be used with kits #1-9 and 13-14; it is part of kit #10.
