So i saw the movie poster of Rosemary's Baby and I thought "hey, make a radio controlled baby pram and have it chase after people with an eerie green glow coming from it and a baby's giggle"...great idea right? well I have NO clue about anything radio controlled...anyone good at it that can help me out? Here is a link of the movie poster and the actual baby pram that I own for my daughter.

Check out "Power Wheels" drive units on e-bay. Use 2 of them and set it up like a tank drive. (real rc speed controlers are $$)

For control you can get a cheep 4 channel set (make sure it's surface frequency) and set the servos up to activate micro-switches to trip relays to drive the units.

This way you can run a 12v lawn battery or power wheels type battery to drive the lights, sound and drive.

The "power wheel" drive units are a geared dc motor they would have enough tork to drive the pram. They normaly mount on the axle and directly drive the wheel. For motor control here is a link from RC tank group.

The MAG set up with micro switches is not that hard to do. It will provide a off , forward and reverse. But the speed is set by the voltage. And it does have a "Electronic brake"

With this simple type of motor control you can use 2 servos with no mixing to do a Tank type forward and reverse left and right..

hope this help some.

Opps.. the Tri-Pact is what your looking for.. use the 2 servos to activate the micro switches.
