Parkflyer Switch-mode BEC
The ParkBEC is the smallest and lightest switch-mode BEC on the
market. ParkBEC powers your receiver and servos much more efficiently
than a standard BEC. As many as six sub-micro servos can be
powered without worrying about an overheating BEC. ParkBEC works
great up to very high voltages, and is especially suited for
running parkflyer type aircraft. ParkBEC is often a necessity at 4s and above.
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, ParkBEC
can supply its full rated current of 1.25A all the way up to 8s.
ParkBEC was carefully designed to not create radio
interference. It uses a shielded inductor and optimized layout, so
you can use it without fear of glitching.
The ParkBEC installs between your ESC and receiver, so you don't have
to modify your speed control to disable its internal BEC. Just plug
ParkBEC is designed for use with lithium aware ESCs. If your
ESC does not have a setting for high voltage lithium packs, please use
the Dimension Engineering SmartBEC
which includes an integrated lithium cutoff to protect your flight pack.
For best results, ensure that the ParkBEC is installed at least 2
inches away from your receiver and antenna.
ParkBEC cannot power multiple digital servos.
