can I use this with Afro esc slim 20a? and cc3d flight control?
 hiteknut 26 points
yes it will Daniel,just remove red wire from all esc receiver connectors before you plug in the bec to receiver. i am using 3 afro 20a with kk2.0 and 2800mah dst1200`s 9x4.7slowfly and this bec and it works great . hope this helps.

can i use UPS battery 12 volt, 7.0 AH for UBEC input, and use output for my Skyzone receiver (5volt) ?

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.

without using a separate lipo for the Rx or not using a voltage stabilizer (capacitor), just asks for a Rx or FC shutdown/brownout and a (most likely) subsequent crash....

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 ***********xlsemi****/datasheet/XL257

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 led begin to reduce luminosity with load > 2A, i not believe it output 5A...

I'm giving this 3 stars, as its cheap, however, the switchmode controller IC is an XL2576, rated at 3amps, not 5.

The instructions also rate it at 5amps MAX (which it will never do anyway) So I have no idea why hobby king are falsely advertising it as 5amps continuous.

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.
