Pinion is 13 and spur is 52.

pinion:spur: 13:52 = 4
Diff gearing: 10:42 = 4,2
total ratio: 16,8
Tire diameter: 140mm (5.51in)
Max Motor RPM: 38000-41000rpm

If i did my maths correctly, top speed should be between 60 to 65kmh (37-40mph). And she does feel a little bit slower than the buggy. I will make a run on this big open place where i shot one of my buggy videos to get the true max rpm value to get a more precise estimate of her top speed. I'm also eager to see how much watt she needs when full speed is reached.
Your truck might be faster then 40MPH.
