Here is a simple cycle control circuit for a two-stage prop. Requires two 12 volt relays and two momentary switches (with "normally closed" terminals).
This control circuit was posted on the HauntForum by TommaHawk. It offers all of the functionality of the first circuit and adds the ability to reverse the polarity (and therefore direction) of the motor.
This is an old hack that I did to a cheap RC car in order to use the radio control circuit to control a larger prop powered by two wiper motors and a lawn tractor battery. It actually worked well, given the limited range of the toy. I ended up doubling the length of the receiving antenna and that helped. This completely mobile style of prop is fun, but really offers potential for injury.
