      David,

      Thanks. I'm still not finding the exact motor,

      http://electromate.com/db_support/downloads/PittmanExpress2011Catalog.pdf

      but I get the idea. 45 oz-in 142 RPM ??

      my 10 kgf-cm = 138.873866 oz-in. So maybe I've just got too much
      torque? I like my ground speed so far, should be 6-7 MPH with the
      1:1.533 gears I have. 1:1 gears would give me about 4.5 MPH.

      Drive pulley is 15 tooth and main pulley 30 tooth.
