Low torque brushless

[suicideneil]

Tricky, anything powerful enough to propel a 5lb truck to 45mph is gonna be pretty torquey I would have thought. What about a low kv motor (1100kv or so) geared up to the desired speed, that way the top end speed would be what you want, but the torque is reduced due to the higher gearing; only issue with that is the load it places on the electronics, so fairly good lipos would be needed + an eagle eye on the temps..
