I finally got some time to play with the robots today. I hooked up a couple of reversible RC car ESCs to the 2 drive motors in the base for the Buster I got. They seem to work ok except for the HF whine. Hopefully some sound deadening will cut that down. I down loaded the new software on my laptop too and didn't have anymore trouble than I did when I first installed the older version a few months back. I just loaded Windows 7 on this laptop a week ago and bumped the ram up to 4gig. The laptop runs better now then it ever did on Vista even when it was new. Those ESCs only cost $11.39 each with free shipping. I got them on eBay but it looks like the guy has sold out. I guess the camera in the head is next. see ya JW

Cool! I wonder if a capacitor across the inputs to the motor might do something about that whine?
Grounding your motors and maybe s inline cap should remove the whine. If that doesn't remove it check "ground loop isolation" its a inline hi frequency filter
it has a cap across the - to + . I'll try grounding the motor housing. I'll check in to "ground loop isolation" (educate myself) thanks guys

@ww321q, What is the max Amperage on those ESCs? Not a bad deal!

20amps, 25 max 30sec, 50 5sec . 4.8 to 7.4 volts.
@ww321q,
Wow, that is really really good for 11.95 a pop! Hopefully they show up again on ebay.

I unhooked the 2 battery grounds and that solved the noise problem . Thanks jstarne1 I was looking up that "ground loop isolation" and was reading on audio systems how they isolate the grounds. JW
They still have them listed in Euros
