Redundant power should be a good thing....
I've been running a UBEC from my 10s for the last 3 years, plus a regulated 730 with rectifier diodes on both connectors to the receiver. (There are lots of opinions on whether that is needed or not.) A couple of weeks ago, I was finishing a round but when I tried to pull out of the spin there was no response. My Integral went straight down.
The UBEC had a burn spot on the wrapper, and under it was a square component that had some soot on it. My only guess is that it was shorting for at least a couple of seconds, and it takes about another second for the receiver to come back from being locked out. There isn't a lot of time when pulling out of a spin, so that combination got me.
I'll still run with this setup.

Ken, if you had a diode between the UBEC and the receiver, a short in the UBEC would not affect the voltage at the receiver as the battery/regulator would supply the required current. The diode would block the current from flowing to the shorted UBEC. How did the system perform after the crash? I believe you need to look for another cause.
