Is there one common obvious cause for this happening?
Mine was 95deg at the end of the 2nd final last night. Running a FDR of 4.01.

I've just had a look at the car. I'm pretty sure the pinion was too tight up against the spur, that would contribute towards the overheating wouldn't it?

try dropping a pinion or two , or if it has timing either on the endbell or escdrop that , but i reckon its best to start with the gearing .
edit , yeah a tight spur and pinion would'nt help atall

There should be a small amount of backlash (movement) available between the spur and pinion when correctly adjusted (meshed).. You can buy meshing paper that helps you get the right gap.. |

It was definitely too tight against the spur. The wheels move much easier now (just using some paper I have here on my desk).
Fingers crossed it will do the job.

Having a too tight of a gear mesh is definitely a cause, be like driving with the brakes on all the time.
excessive timing on the motors end bell will also make the motor very hot, having max timing isnt always the way forward.
When i dabbled in mod TC it was the other way around, motor was rather cool, ESC Came off at 120 degrees C! still was fine as well haha.
