Sidewinder SV2 vs Castle Sidewinder SCT vs HPI Flux Motive vs Duratrax Element etc

[fastbaja5b]

Am looking at a waterproof brushless esc for my Wraith, now the stock location is for an Axial AE2 esc which is essentially a rebadged Sidewinder without the Brushless (or fun) capability.

Problem is, I see SV2 Sidewinders and Duratrax Element as non waterproof, but HPI advertises their new Brushless with the Flux Motive as "waterproof"

So whats the difference and which one can (should) I use?

Does the HPI sticker result in some sort of voodoo magic that causes water to stay away??

AE2 shares nothing with the sidewinder apart from the case. Same as the HH BRXL. If you want a waterproof BLS esc, perhaps try the tzi world waterproof sidewinder? I believe it is dipped in plastic to keep the water out?

Out of stock, but here's the link

Just remember the HPI ESC's are locked from using beta software...

HPI asked us specifically for a waterproof controller. So the HPI version is fully waterproof, epoxy encapsulated.

what type of epoxy do you use to waterproof your esc ??

An ultra-low viscosity epoxy for potting electronics. It works well because it gets into EVERYTHING.

A little off topic here, but what affect does waterproofing have on ESC temps? I know the FETs are attached to the heatsink, but what about the BEC? Switching BECs are far more efficient than linear types (and so produce less heat), but there is still some heat to shed. Does the PCB wick enough away to compensate for absolutely no airflow?

I've been wanting to waterproof a couple of my ESCs (knowing full well about voiding any warranty), but this has been a question on my mind.

Could plastidip be used to incapsulate a esc?

We have also been in our dispute about overheating components:
Some say this way: cooked in a closed condition, that ESC will overheat and burn up that there is no heat from the Component board.

My opinion and the other part of speakers that take the most rasprosanenny ESC - MMM V3-V5
BEC, Drivers, CPU gives off heat through the board to heat sinks a free stream air cools and board and all installed components.
From here our apanentam question?
as a closed case "in the air" environment in the stock cooled allegedly overheated in an epoxy resin or other details
If the thermal conductivity of air under the back cover ESC 0,026 [W / (m · K)]
thermal conductivity epoxy thermal conductivity of ~ 100 times higher
