SportBEC Switch-mode BEC
SportBEC is the higher capacity version of our best-selling
ParkBEC product. SportBEC powers your receiver and servos much more
efficiently than a standard BEC. As many as 8 servos can be
powered without worrying about an overheating BEC. SportBEC works
great up to very high voltages, and is especially suited for
"sport" aircraft and glow conversions.
SportBEC is usually a necessity at 4s and above when running high
torque or digital servos.
SportBEC's output is selectable between 5V/6V using a small
slide switch. The 6V setting gives more speed and torque to the servos,
and is especially useful for helicopter flyers. A red LED indicates
when 6V is selected.
Many people don't realize that their ESC's BEC rating is misleading.
With the linear BEC built into most speed controls, the current rating
decreases as pack voltage increases. For example, several popular 25A
ESCs with "3A" BECs are only capable of supplying 0.5A when running
from a 3s pack. Because it is an efficient switching regulator, SportBEC
can supply its full rated current of 3.5A all the way up to 8s.
Many design hours were spent on SportBEC to ensure it does not create
radio interference. It uses a shielded inductor and optimized layout, so
you can use it without fear of glitching.
SportBEC installs between your ESC and receiver, so you don't have
to modify your speed control to disable its internal BEC.
For best results, ensure that the SportBEC is installed at least 2
inches away from your receiver and antenna.
If you are using small servos make sure they can run at 6v. Some
sub-micros, notably the Hitec HS-50 and Futaba S3154, can be damaged by
a 6v supply.
