Turnigy 5A SBEC is an advanced switching DC-DC regulator which will supply a constant 5A. It works with 2 - 7 Cell Lipoly pack and supplies a constant 5 or 6v to your receiver and is interference-free.
i have one of these on my mini octo and some times when using over half throttle my kk board would turn off mid flight but lucky it was low for most of the times but on the last it fell about 4m breaking some of the arms . i have checked the soldering and i don't think it is that but the only other option is the bec.
I went to see weather I could alter it to output a higher voltage for my servo. So I goggled the data sheet and found that the chip is rated at 3A and not 5. Very dissapointing

I bought this back in January to use with my T-Rex 500, since I wanted more than 3 amps to use with a standard tail servo. Unfortunately, this BEC will not supply more than about 2.5 amps, not the advertised 5amps, without dropping voltage to less than 3 volts. I had several issues while flying, which I couldn't figure out until I hooked the BEC to an ampmeter and found out how few amps it actually supplies.I would give it 0 stars if I could.
The description of this switching BEC is misleading. It will supply 3A continuous, but the output voltage drops off at any current draw higher than 3 amps. The ripple voltage is also extremely high compared to others and what would be expected from a power supply of this nature. The heat created is also unacceptable. Power hungry servos like the HXT900 (at 500mA each) would stress this BEC if using 6 servos. The only good thing is the ability to handle 6 cells.

The BEC has almost 1V peak to peak switching noise at 2-3 Amps. At 5 Amps the output dropped to 3.5V. The Hextronic 3A BEC is much better. Glenn.
