The Hobbywing 8A-UBEC is a
switching-mode DC-DC regulator supplied with a 2-3 cells lithium battery pack
and it outputs a consistent safe voltage for your receiver, gyro and servos. It
is very suitable for nitro powered RC helicopter (bigger than 30 class) and big
fixed-wing aircraft.
Compared with the linear mode UBEC, the overall efficiency of the switching-mode
BEC is much higher, so it can extend the working time of the receiver battery
pack, and because a switch mode UBEC can significantly reduce the heat emission,
it can avoid the loss of control caused by the over-heat problem which is
frequently happened with the linear mode UBEC.
