Can you tell me the size of the old motor?

But honestly I find myself wanting a sensored brushless motor.
The sensorless brushless motor can't drive slowly on anything but the road.
sensorless brushless motors have tons of torque on high speeds but almost none on lower speeds.
sensored brushless motors have torque on low and high speeds.

That's what I paid for mine!
It is a great deal. I have mine and it goes ~40 mph.
oooohh.... mine at the moment only hits 40kmh... and that's on a perfectly flat straight tar road...
can't wait to unbrush it and see what it can now do on the farm:p...... unfortunately it's a low swung car.... so off roadishness is rather limited by ground clearance.... unless..:unsure:

who wants torque at low speeds(n)(n)(n)(n).... high speeds are way more fun... especially when you strap a phone on it and record the track... makes you feel super...:p

Okay. then if you can't already drive offroad then I would go wtih sensorless.

hmmm.... oh boy i can drive off road.... just put up ramps at the beggining and ends of the tall grass areas... full throttle and fly/leap over those areas.... just aim right or you hit a tree...
