I like how you think!  It would be a good idea.  Somebody should experiment! 

(edit: upon some research, a lot of thermal tapes are not very conductive. Many people complain of heat increase. Until I find a better tape, I think I'll have no thermal tape for now.)

I've used heat sink paste on helicopters. Seems to work okay.

Traxxas sells a thermal paste for use with one of their heat sinks. Not sure if that means anything…

Interesting, that will mean it can be used on our cars as well. Now to dig into my IT box to find some, perhaps to try on an old motor first. 

The best thing to remove heat from a source is to blow cool air past it.  I would try a fan before I spread goop all over my motor...

As you had seen in my TD build I had to remove the fan to just fit in the heatsink with no room left at all. So a heatsink only job. 

That's right, I forgot.

Yeah, I had to jimmy-rig a fan on my Dragon.  Though I'm sure I need it since I'm running brushless now...

Thermal pads might be an idea too, cleaner than paste and can be trimmed down. They do much the same job.

The pads we have are pretty soft and will bend fairly well, at least on the circumference of a 540 and likely a 380.
 

I’ll try mind on and snatch some from work and test. I’d have no qualms about removal either.

This is something I thought about a few days ago when I've ordered a motor heat sink for my WR-01 chassis. Do the paste hardened after application? Otherwise it will be a mess with all the sand and dust and dirt.

[ad456 469]

That’s why I was thinking of the pads as thermal paste will indeed be tarry and pick up grit etc. 
It’ll dry eventually but that’s really when it loses its effectiveness too.

It's a good theoretical discussion but I suspect the applications are limited at 1:10 scale.

...You can tell that the contact to the motor is quite poor given then amount of sand and dirt that can get in between them...

That's an unsuitable heatsink for the motor, no amount of tape or paste can fix that problem.
