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 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.

26 thumbs up!
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.
