I plugged in your info here and used 4.5" buggy tires as a guide. this is a great tool for speed estimations...an even better tool to determine motor RPM which is key to motor longevity, long run-time and performance.

Based on your #'s top speed is 42 or so w/a 17t pinion and motor speed of 29k. W/a 19t pinion=46mph


1. MBX-6 T8 1900KV, RX8 ON 4S
2. MBX-5T 1520, MMM ON 5S
3. MBX-5 ONROAD CONVERSION 1515, MMM ON 5S
4. MRX-3 ON ROAD CONVERSION 1512, MMM ON 6S
5. TEN T 2650 T8, MMP ON 3S
