Hi all I have a quick question. I have a couple DC drill motors and gear boxes and I wont to make a robot. I am looking for a 20ish amp motor controller. I either need a dull one of two single ones. What do you all recommend? It needs to be able to plug into a regular receiver since I am going to be using a Dx7s and a simple dsmx receiver. I could be biger than 20 amps just I thought 20amps would be a good base line. I want to find something cheep like under $50.
Thanks!
Pololu would be a good place
Pololu would be a good place to look. They have a number of different options in that price range for motor drivers. I have been very happy with the hardware and more importantly the support I have received from them.
You could easily on startup do over 20 amps if you are under load. I would use an ammeter, put some load on it and run some tests as to what you need and what the instantaneous load that can be handled by is.

Bill
