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

guys I don't know how to use this so please help

the input wires goto your battery, either solder them onto the battery connection wires of your esc, or the skt of the esc for the battery, the output wire/plug goes into the receiver,(Rx)

YOU MUST disconnect the red wire from your ESC's connection to the receiver (rx), or else you'll be giving it too much juice!!! Your other option is to wire the output directly to the item you want to power, usually the servo, along with the white signal wire coming from the rx (see File "DirectPower.jpg" or target=_blank>DirectPower.jpg).

IF your ESC has a bec you need to cut the Red wire, (opto's don't have a bec) so you don't for an opt ESC, ..........MANG do yourself a favor and forget this bec and buy an esc that has it built in, most do now, only for multi motors you need to muck about.

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.
