Operation

1\) Before running any experiment, make sure the assembly is clamped down to a surface such as a table or desk. The rotor speed may force an unsecured assembly to fall off and be damaged or cause damage to nearby objects.

2\) Make sure the propellor is pressed securely onto the motor shaft to prevent the propellor from flying off.  These are **pusher** propellers, so they face down and are pressed into the motor during operation when assembled correctly.&#x20;

3\) When operating the assembly, keep fingers and other objects away from the moving rotor.

4\) Be sure to secure long hair, remove dangling jewelry, keep clothing, etc, clear of the system while in operation.&#x20;
