DAF,

I was doing some calculation and found that the sliperential and the buggy diffs gave a rather low gear ratio. Almost dificult to gear it up high enough. WHat KV motor are you running in that and whwat pinion/spurr gear are you running with it? Here is the genaric values I entered, but it seems with the ''average'' setup it is dificult to get the gear ratio up at all. In the below numbers I assumed the smallest revo spur available and the biggest pinion available on the RC-monster store.

That is actually one thing that steered me away from the slipperential. I was concernend about the flexability of the gearing ratios.

How do you have your truck setup? Just curious.

Differential Ratio: 3.3076923076923075
Transmission Ratio: 2.2
Other Ratio: 1
Spur Tooth Count: 38
Pinion Tooth Count: 20
Total Voltage: 14
Motor KV: 1867
Tire Diameter (inches): 5.6
Tire Ballooning (inches): .25
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1.9 : 1
Total Ratio: 13.82615 : 1
Tire Circumference (inches): 19.16 inches (486.76mm)
Total Motor Speed: 26138 RPM
Vehicle Speed: 34.31 MPH (55.11km/h)
Effective Speed Rate: 2.45mph/V (3.94kmh/V)


I can't decide if its more fun
to make it...
or break it...


Silent...But Deadly
