« on: March 05, 2012, 12:09:17 PM »
Hello there, I'm lookin for some help! I'm makin an rc car driven by 2 wheel chair motors and powered by 2 - 12v car batteries that drives like a tank. I know i need two build two H-bridges one for each motor. The problem I'm havin is that i dont know what i can use to control them would a normal rc and transmitter and receiver be ok? If any one could help would be grate, a list of parts (cheap would be grate) or another way of doin this would be cool!

You could use a Sabertooth motor driver such as the 2x25. http://www.dimensionengineering.com/Sabertooth2X25.htm

Sabertooths motor drivers have an RC mode that can be used with a normal transmitter and receiver.

Take a look at http://www.pololu.com/catalog/category/10. Depending on how much current you'll be dealing with one of them may work for you.

I am building a tracked RC robot similar to what you described and I am using the 2x25 Sabertooth. It is really easy to setup with the RC receiver.  It is worth the money.
