Default Tamiya tt-02 motor question.

I just picked up a barely used tt02 it came with a castle 4600 2 pole motor a ocday 5200 motor and of course the stock motor. I wanna run 1 of the brushless motors in it. Which would be the safest option without destroying the gears. Everything is stock and I replaced the bushings with bearings

If I'm reading things right that's a 4600 kv and 5200 kv motor.
For reference,
the 17.5 turn motors you read about are usually in the low 2000kv range
the 10.5 turn motors you read about are usually in the low 3000kv range

With the super high FDR that the TT02 runs stock, you won't really hurt anything. It's just going to be 'very' punchy off the line.
You'd probably go just as fast as a 'slower' motor with a lower more race friendly FDR.
meaning, the pinion gear is so small out of the box, and the spur gear so large, that minor changes to motor speed really don't much to change the speed of the car. But if you had a very large pinion gear, or a smaller ('high speed') spur, the motor changes become more apparent.
Only thing I'd be concerned with is cooling at those high motor speeds.

Safest would be stock, next safest would be the slower of the two motors, etc.

Are you sure about those numbers? 21.5 motors are usually in the 2400-3000kv range.

honestly I'm not I just went to the Reedy website to look at their ROAR approved motors and for zero degree timing that's what it gave me.
the 21.5 gave me 1900kv. I checked with hobbywing too same story.
