Nice solutions on the drive. Wish I built smaller so servo could be used. Maybee some day....

Thanks Modelman, I believe there chain will fix it.

I only used the servos because the hoe is small & light (probably less than 6 lbs when complete). If I had the room and needed more power I would use a 200:1 geared motor on each track and esc's. But, I am making the undercarriage all one rc unit...meaning there will be a (4 cell 500mah) battery pack and a separate receiver just to run the drive. That way there is no electrical connection between the crane/house and the undercarriage.

Yes, Servo City has some nice unique servo related items that you can't get/find anywhere else. Adapters, sprockets, reduction units, aluminum arms...
