Does it void any repair options if I open the case?
The absolute most it will cost you is 45 bucks.But i sent 1 in that I had resoldered a connector on the board just to have something else fail later and they replaced it for free.If it's over 30 days old it's supposed to cost 20 bucks.So for me it was worth the risk.
Looks like a sticking switch. I opened the ESC, the switch on the board is working properly, however, the switch/connector built into the top cover of the ESC appears to be sticking. What's the best way to clean this? Just use the compressor and try blowing it out, or use something else?
that happened to all my vxl escs, i just pop the rubber ring out lube it up with lithium grease, and spun a exacto around the hole a few times and polished the button. I removed the sticker from the esc on a couple because the sticker goo kept creeping in the hole as it got older.
