Yup, it looked sad in your buggy. So I decided to take it for a walk, and a tumble, and a mid air hack from underneath... you get the picture.

Wow the track layout looks fun for Hotrod. I like it better than the shootout layout.

Cant wait till round 8.

what is everyones thoughts on motor coolers such as the Crazy RC one, is it doing any damage to the motor going from one extreme of freezing to the other being hot.

Not sure what the R/C crazy cooler is. I have not heard of anyone damaging a motor from cooling a motor. They will run more efficient at colder temps and the magnetic field should be stonger. The motor should be much cooler at the end of a run as well.

I think he was refering to http://www.crazyrcracing.com/2.html which is a very full on "post run" cooler.

My main worry would be quick temp change. Any material, if you go from HOT to COLD too quickly you can change the properties of the item. I would be worried that if it went from HOT HOT to cold too quickly you could crack something or weaken something and have a serious failure.

Back to backing runs is a pain, but maybe just a normal fan to get airflow will be suitable, and like casper suggested, maybe installing a fan into the car with a motor heatsink will lower the actual running temp of the motor.

Cheers, Daniel

The condensation part of this is not really a good thing. I would not recommend having your motor wet when you run it but that is just me.
Again cold is a good thing for an electric motor. I personally would not recommend putting a hot motor on a very cold surface like this as the thermal shock could cause the epoxy holding the magnets to fail or possibly (not likely I don't think) an magnet to crack due to thermal shock.
