Remember work upside down! And things might stay in place

Dude I worked right side up, side to side, upside down on my head, still lost half my religion in the process

What would we do if this hobby did not exist?
No need to answer. This might get scarey and weird.

Watch the grass grow, clean house, live longer, any of that normal people stuff

Has anyone tried thermal paste yet?

I debated paste but the problem would be getting the coating completely even. And I read the paste would be a dirt and junk magnet

Just a heads up for all having heat issues with motor. Using the brakes on a brushless rc will cause the heat to build up fast. The motor actually ever so lightly goes into reverse to stop the rc. This causes most of the heat besides running in grass or spinning the hell out of the tires in hard packed dirt.

I used thermal paste between the motor and heatsink. Sure it will attract dirt for exposed grease, but it is between the motor and heatsink and the rest washed off. It kinda helps make a better connection for better heat dissipation. It is used between computer heatsinks and CPUs so it has got to help. Other people have used thermal pads 1mm thick.

I'm going to do my kraton exb. Probably going to get the 0.5 mm pad for it. Debated giving the paste a try

Might just give the paste a try then. Everything I've read up in computer forums says the thinner the better transfer and paste has better transferring capabilities than pads do

I just don't see the paste working that well.
Mainly the heatsink is going to push all the paste out. Leaving a uneven maybe none at all paste left in places. IDK !
At least with the 3s and 4s heatsink.

I see liquid cooling as a next step of madness

I see NO heatsink and the fan blowing directly on the motor...

It's possible but according to computer building nerds the thinner the better because all you want to do is fill in the imperfections, make a full contact surface and that's it.

If it didn't already have a heatsink with a dual fan set up maybe, given I already have both might as well make it work like it's supposed to

So last night out of boredom I studied up on thermal pads vs paste, and when it came to performance of transferring heat the paste wins hands down every time. I'm definitely going to give the paste a try on the next go round

Same method of madness. Force the the heatsink open and insert motor? Or slide the motor in?

Spread the heatsink open and put the motor in, clamp heatsink down, wipe up any excess squeezed out, and call her good

Just ran 2 3s in my kids bigrock. Ran hard for 3 solid minutes and motor never went over 80 degrees. 40mm × 40mm 12volt fan,.05 thermal pad.
Should be ok for kid use and no over heating. True test will be Kyle my 12 year old. Toggle switch for throttle kid!!!

That's pretty dang impressive!

The fan is the real work .

Yea I've debated trying some of the taller fans when the rockets die out
