No fan on the 9920 (yet). It has not cut out yet.
There is 2 tracks close by. One is very fast with BIG jumps and good traction one is smaller and poor traction.
Amazingly the faster track keeps everthing cooler (I guess alot more airflow) but it is HARD on the car.

On the bigger track the jumps are larger and I had to put rear support on the motor because the motor mount came apart. I WISH SOMEONE WOULD MAKE A MOTOR MOUNT I COULD BUY THAT WOULD INCORPORATE THE DIFF SUPPORT..

Trying not to Hijack we need to get back on track.
