MM,

the servos I'm using are labeled as micro servos. The way I have it now, the pinion is running against the ring gear. The only trouble I have is that the ring gear is cast as part of the lower track unit and was never designed to be functional, but the teeth seem to match fairly well with the pinion I'm using. My trouble is getting a good fit to hold the pinion in place. I think i can get it, just wondering if a elastic o ring might reduce the tolerance needed with my current method?

Thought I was going to be filming a test by now but still a few bugs to work out.
