I am so done with cheap Controllers!

I have used CorrosionX for years on my receivers and ESCs - no problems. Conformal coatings are not as good a general protectant as many think - most are too viscous to get where they need to be. Example: the most vulnerable parts of Castle controllers are the plugs between the boards. A drop of water inside the plug and a short happens...poof! CorrosionX will get into the plugs and saturate them, giving at least some protection. Most conformal coatings are too thick to get to these hard-to-reach plugs, so protection is reduced. They worked great on Andy's ESC since they were simple with all components on one board.

Tell that to Schulze, for years their marine controllers were "splash proof"....
.

This is why I encase this area in proper epoxy. All hifei/SF esc's have this plug as well and are also a weak link that I take care of right away. If it's totally encased is totally encased very much like Schulze's U-Force esc or HobbyWing HV 130A esc.

Yep, weak links like poor driver fets or poorly soldered fets in general will make short life of an esc, thats why I tear off the shrink and attack my Chinese units.

It still doesn't give you 100% assurance though.

Okay, who's messed with one of these?

Are they on/off switches or speed controls?

That is a Hifei (swordfish) controller

I have that exact one and posted pics of it burnt by lipo melt down and it survived. Best get it from Steve but, mine is still ticking.
