It doesn't sound like a sensored motor issue per se, just that the kv is kinda low for the voltage being used. 17.5 turn is probably a low kv motor. It just sounds like the motor is not spinning fast enough at low speeds for the ESC to get a good rotor position reading.

Increasing the start power and twiddling with the throttle curve should help a lot if this is the case. You gotta get it spinning fairly fast right off the bat, then the ESC should be able to read positions fine.
