lol, what, you didn't believe me?
That was just a measly 250mA - imagine that with a ~2A servo load? And those chips aren't even on a heatsink. Even on 3s and 250mA load it gets toasty, which is why I say use a UBEC on anything over 2s or 7 cells.
It has a use, but only for 2s setups. But it is useless for anything over that
