This truck is just not fast enough, so it was time to move on to 6S.
Leopard 3650 Motor (540 can)
2090Kv 3.5Y, 4 Pole, 1300 Watts, 28V Max Voltage, 46A Max Amps
The motor bolts right up to the Tenbol mount and the motor shaft is 1/8", just like the Castle 1406. The motor has 6mm bullet plugs and the Mamba Max Pro ESC has 4mm plugs, so I ordered some adapters to make that connection. I trimmed the Tenbol mount to accept a 47T pinion gear. I'll be running 47/45 gearing and two 3S 2200mah 65/130c batteries in series.
