Interesting...

I have seen on my many travels that for high powered servos, esc manufacturers recommend running an rx pack (of sorts) wired to the servo in series ( I think) via a y-splitter, so that the esc was only really providing the signal to operate the esc, with the rx pack providing the go-juice; rather like having a glitch-buster capacitor plugged into the rx.

Not the most compact or elegant solution, but one of three options along with the cap or running an external BEC..
