[F-1]

Hello! Today I was tested my new SP v3 5.5t motor... After 7 min of practice I'm having 110 degrees of celsius!! Mine overall gearing is 9.86. I'm using neutrall (0?) timing on the motor. I have the holes in the body, but temp of Air was 32 degrees today.. Help me please, is it normal? I was tryed min timing on ESC.. But! After 5 min practice I having 100 degree...

sounds like your way over geared, what car pinion and spur??and whats the track like

[F-1]

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..

dont know alot about the tamiya, but may be drop a cog or two,our overall ratio is slighlty lower,im sur of the tamiya boys will be along shortly with pinion and spur ideas

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?
