Motor Selection

[Heavy Metal]

I did the math again and motors I selected would do 27' per minute (.45 FPS or .31 MPH) assuming my target tire diameter of 4.14". That's pretty darn slow for moving from one job to next! I obviously selected these motors for the power.

If I stick with these I definitely need to think about way to adjust ratio. I can't mount them directly to the axle anyway because I miscalculated available space for two motors back to back...the model would need to be 1:12 for both motors to fit between the rims like that (and since I want to haul it w/ 1:14 truck...I'm sticking w/ 1:14)! So offset mount w/ spur gears driving axles would be my thought...then could change gears later if I want to go up or down.
