Tekin T8 1700kv truggy motor power delivery

[RC-Monster Mike]

The 1700Kv Tekin Truggy motor is delta wound(2.5d - same as the similar 1515 Neu). Not as responsive to timing like a Y wound motor. This issue sounds more like a throttle profile or punch setting than timing to me (or dislocated rotor) - a dislocated rotor would make it feel like it has no "pop" coming out of corners or when trying to get over a jump with short run-up. The low end would be similarly affected, though. The sensor wire shouldn't be a factor at all.
For linear feel, the throttle profile "3" should be used, along with "0" on the throttle exponential. "4" and "5" throttle profiles should be rather aggressive/difficult regarding low-speed control(twitchy), and "numb" when beyond 50% trigger movement.
