thingiverse

To keep your motor running cooler during consecutive flights, you'll need a few essential components. First, grab a 5-volt, 50-millimeter fan that will provide effective cooling. Next, obtain some 3-millimeter bolts to securely attach the fan in place. Don't forget to get a 3-millimeter tap to create threads in the holes where you'll install the fan's mounting screws. To complete the setup, simply Velcro a 2-cell or 3-cell battery pack onto the motor assembly.
