Tekin Redline brushless motor

[Mister-T]

Play in the rotor you mean, like side play or like a movement to remove the rotor from the can ?. I have 0 side play on mine and same lateral play as feigao motor.

4800 kv motor is most likely to be used on medium track for off road, i wouldn't go under 5800 kv for onroad. Car with small tyre are more RPM based. That's why TC guy prefer sensored, because most sensored motor can goes up to 12000 kv and small rotor allow fast spool.
In off road you will just spin the tyre and lost all grip doing this
