You mean we have to add another two motors?!?! Say it ain’t so, Kit!

i sure hope you don’t have to add 2 more. we’d surely be in trouble then.:eek:
Option 1 (current)
Drill Motor, low gear, 1:2 ratio, 8" wheels
Calculated Speed: 5.23 ft/sec
Measured Speed: n/a
Option 2 (backup)
Drill Motor, low gear, 1:3 ratio, 8" wheels
Calculated Speed: 3.49 ft/sec
Measured Speed: n/a
Initial ratio - Failed- Too much motor stress, tripped 30A breakers
Drill Motor, HIGH Gear, 1:3 ratio, 8" wheels
Calculated Speed: 11.63 ft/sec
Measured Speed: n/a
