8ight T conversion

OK, I messed with the torque settings. I set it all the way up to "dynamic," whatever that's supposed to mean.

The short of it is that the Neu 1512 1.5Y doesn't have nearly the raw power of the 9XL. I have the Neu geared 17/46 and it still doesn't equal what the 9XL was doing at 14/46.

Still in all, the 1512 only gets up to around 165*F. I was hoping for lower temps, but they don't seem to get any higher either. If I run it for 5 minutes, it temps 165. If I run it for 15 minutes, it still temps 165. If it keeps running like that, I'd be fine with it.

I haven't tried the 18T pinion yet and I can still go down to the 44T spur. I'm just afraid to try it because I'm already getting a bit of cogging.

Your supposed to gear a higher kv motor down.... not up! Go back to your original gearing that you ran with the 9xl and tell me how it feels. Gearing the 9XL up as high as you geared the Neu 1512 would cause it to overheat in minutes. The fact that you are running it at only 165 is a testament to the Neu. Also the 9xl will feel less torquey at that gearing.

If you not getting more speed out of it at the same gearing you for sure have something wrong with the motor. At the same gear ratio the higher KV motor on the same power source should run at a higher speed.

Gearing them the same should give you a better view of the relative power of the 2 motors.

EDIT:
if you get 35mph on you 9xl geared at 14/46 and you are looking for the same speed/power only coolier temps you would need to gear the Neu 1512/1.5Y down (very slightly). Gearing up will naturally give you more top end and less low end.
