Rvjimd-The standard way is to let the pinion gear run against the swing gear. However I understand you have to do what you can with the room you have. On the pictures you posted,I cannot see what is what.(eyes) Are the servos in the model mini servos? Also I cannot see the detail of the drive sprocket but that is okay. Just keep doing what you are doing and I think you will have an operating model soon.

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.

Well, I did manage to get one video of the dragline as I tested out the slew function. I was having trouble with the gear mesh of the pinion and ring gear and you see me help it where the mesh is too loose.

Also the drag servo drum loosened up so I got that to look at this weekend.
