Fried receiver - cause?
I fried a brand new Spektrum receiver tonight. Everything was running fine and it just stopped working. My electronics got hot and my receiver has that burnt electronics smell. I assume this would be caused by a short somewhere but I'm stumped where.
My ESC seems fine. It powers up still when not plugged into the receiver (does not when it is plugged in).
So what are the likely culprits? Is it likely my ESC is damaged too?

Savox servo? Sounds like it went belly up due to current draw through it?

Cap wouldn't do anything in this case. The cap is only to prevent loss of Rx due to voltage droop. It seems Savox servos are notorious for large current draws. Maybe the traces on the Rx circuit board can't handle the increased current draw?
That really means that these Savox servos must suck the power, since I've never had any issues even in 1/8 truggy with a JR DS8711 403 oz/in servo. Does the servo still work? Maybe it has a short?
Just get a Futaba BLS551.

All I can think of next is to try ESC and servo on another system, if you can find someone willing to try it. They do make servo testers that are about $15 - $20.

Remember, pieces of carbon fiber and carbon fiber dust etc are also conductive.
I now take apart my Spektrum's and cover them in a 'conformal coating' like this;

It prevents it from letting anything make contact with the actual circuits.
I use it to waterproof my receivers and the sensor board's in motors for running in the wet.

Of course.
While a good idea for your specific application, it more than likely voids the warranty. And that won't prevent a piece of metal from shorting the servo connector pins, since you can't conformal coat the pins otherwise they won't conduct.
