Can I use this bec with turnigy k-force 120A hv opto v2 5 - 12s brushless esc ? And im run cyclone power ir600 - 1500 - 50 1500kv brushless motor on edf jet 90mm with 6 turnigy tgy-9018MG metal gear servo.. on 6s lipo battery. . Please help me :'(

yes, you can use with that battery, but i would go for another choice, it looks it is a big plane, so, choose the 8A bec and also get a spare 2 cell battery (1500mah or similar) to power the bec, so, you will never get a blackout when pushing the esc to its limits and in case of low battery (flying battery) you will always be in control no matter what

hi all, i have an old speed controller (turnigy multistar 20amp) and it has a sbec in it(5.5v 4A). could i use this as a bec to power only my reciever in a nitro car. i can solder off the motor wires. the reciever im using is the hk-gt2. i am running 2 servos. help would be greatly appreciated.

yes of course you can, just make sure the motor outputs don't short out when they are shaking around, or desolder them like you said

That would be a way of saving some cash, especially if you can de-solder the motor connections, it is just a bit bigger. Make sure you insulate it.

in addition to the comments above, remove the signal cable from the JR/Futaba plug so you will get no interference

Not so sure about the questions and answers :) Anyway this has been very good sbec for planes and little extraordinary projects! Tested also with 8s but of course not recommended.

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.

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.
