I found the two-part thermal epoxy to work great

You can see the pics attached. The cure time is about 24 hrs room temp but you can boost it to just an hour or two if you elevate the temp. I provide more details in my thread on ESC cooling in the FE questions and answers forum.Attached FilesComment

I tried to skim through all the pages and still wondering if you could waterproof with liquid electrical tape. It's not conductive. What's your thoughts about this?If all of your wishes are granted, many of your dreams will be destroyed!Comment

That stuff should work fine. The problem I see is will will hold heat in.
Still should be fine the epxoy 270 is about the same...anything on them will hold some heat in but keeping fets cool is the key.
I even thought of just spray undercoating in the auto section but not sure the stuff will eat anything without testing on something first.Comment

Yes but it has little particles in it...sand or soemthing but it would be nice to be able to drop a brick on it and have it still runComment

You could do some tests on it, but the recommendation to use a 2-part epoxy that was designed specifically for electrical isolation but good thermal conductivity is what I would stick with. Rubber based products like bed insulator materal would also probably have poor thermal conductiity.Comment

Very true. Hereis the make up of 270
It is certainly better to use something made for these components.Comment

I made water cooling on my HiModel GX 200 using a 3M Thermally conductive tape
3M Thermally conductive
This 3M product looks fine. What is the best way to waterproof my ESC ? Thanks

you could use vacum line from an auto parts store.NAMBA20...Caterpillar UL-1, P-Spec OM29, P-Mono DF33, P-Spec JAE, Aussie 33" Hydro-LSH, Sprintcat CC2028 on 8s, PT SS45 Q Hydro, PS295 UL-1 power, OSE Brothers Outlaw QMono 4-sale, Rio 51z CC2028 on 8sComment

This is a neoprene tube for gasoline very strong and nice looking, 3mm inside and 6mm outside

I'm on my way to try out some auto vacum line since they are two blocks away and use it on my CAT UL-1 for the all black hardware look.NAMBA20...Caterpillar UL-1, P-Spec OM29, P-Mono DF33, P-Spec JAE, Aussie 33" Hydro-LSH, Sprintcat CC2028 on 8s, PT SS45 Q Hydro, PS295 UL-1 power, OSE Brothers Outlaw QMono 4-sale, Rio 51z CC2028 on 8sComment

usally to water proof the esc some form of conformal coating is used.
what i use comes in a spray can, i give it a few coates and let dry in the sun for acouple of hours, then take it out of the sun for about 1 hour this lets it harden. then i sand the conformal coating of the top of the fets and add the cooling plateComment
