I have running Tamiya TRF511, Spur is 91, pinion is 19. Gear of the car is 2.06.
Our track has astroturf surface with high/medium grip. And the track has medium size, smaller then Bilbao's Euro track. |

The manual of the motor says, what 5.5t motor can running on 8.8 overall gearing..

How hot is safe with brushless motors?
My motor gets pretty damned hot but I think brushless can take much higher temperatures than brushed motors. Obviously a lower temp is pefered as your car will be more efficent. But I dont think that a hot motor is a major source of concern. Should I be more worried about motor temps?

I think it's the same for most motors. The high temps will desolder the connectors inside and the magnets loose their magnetism when reaching certain temps.

Motors can get hotter when little or no parts of the track use full throttle.
I found using a 6.5 instead of an 8.5 on a small track increased temps. On a large track the 6.5 stays very cool. Try a higher wind |
