In the past, fans were allowed (and expected) to be connected directly to a 20 circuit breaker. I am surprised that an inspector required a Spike for this purpose. The rules specify which loads a Spike may control.
The fans in this size origianally were small and looked like they were made from muffin tins. (unpainted aluminum rotors and housings look just like aluminum cup cake or muffin tins.) It has become common usage for all small, square fans to be called 'muffin" but each manufacturer uses a different term in referring to fans of this type in different sizes.
Be aware that the Chalupa motors (both large and small) are closed devices and blowing cool air over the surface does little to cool the inside. The only conduction to the armature is through the end plates and shaft. The same can be said for virtually all motors in our kit even if they have openings in the case. If your motors are running hot in a two minute match, you should reconsider your design calculations. If they are running hot during long practice sessions, then do whatever you can to keep them cool so you don't have to replace them. Burnt motors stink forever.
BTW, remember you can't modify the motors in any way other than to facilitate mounting or shaft mods. See the robot rules. I know what you are thinking and drilling holes in the Chalupas is illegal and reduces the output power of the motor as it reduces the magnetic field.
