Sbus receiver, futabe HV servos. I dont see anything wrong with my wiring to my other electronics, which leads me to believe that i might have just experienced a sag in a lipo that might be wearing out. thoughts?

So what do you think? plausible? Or do i need to keep looking
Lipos do go bad but it could be a servo too. Test it on the bench by setting pitch pump to 100 and slam the collective and see if you can reproduce the failure.
