Hello everybody.
I'm currently building a micro quadcopter, and I've run into a bit of confusion and I'm struggling to find the information I'm looking for. I bought four of these components, believing them to be 6A ESCs I could use for my quadcopter. However, by looking up the abbreviation 'UBEC', I'm now worried that these aren't ESCs at all. Could somebody please clarify for me what these components are?
Thanks in advance.
It is in fact a 6A speed controller (ESC)
I think, therefore I crash
They are ESC's (Brushless Motor Speed Controllers). They will supply up to 6A to a brushless motor. Your clue to identification is that there are 2 wires in and 3 wires out. This shows it is a speed controller. A true UBEC has 2 wires in and 2 wires out and ONLY changes a higher to a lower voltage, usually 6 to 3.3V output.

Ah good, thanks for the help! I was starting to panic, as I've already soldered them to my quad frame and removing them would have been a pain if they turned out to be the incorrect component. Another question I have is that since I'm using a LiPo battery, I realised that I'd have to reprogram my ESCs to not cutoff with low voltage to avoid my quad crashing, but that I'd also need to have a LiPo Alarm attached to the battery during flight to ensure that I don't damage my battery by over-discharging it. How do I connect the alarm? My battery has two leads, one for the main power which will be connected to the power leads for my ESCs and one to be plugged into the receiver to power that and the control board.
My question is that how do I plug in both the receiver and the alarm to the battery? I assume I'll need some kind of cable splitter, but I've been unable to find one anywhere. Thanks in advance.
Nope, the battery alarm should go to the balance lead on the battery, which is unused in flight.
Oh, then how is power transferred to the receiver and control board?
through the receiver plug on the esc which is the red white and black lead coming out of the left in the picture, next to the battery leads. You plug that in to control the esc and that's also how the esc feeds the receiver and servos is you had any.

Oh, I didn't think of that! So basically, my ESCs will feed power through their 3-wire cables into my control board, and then the cables from the control board to the receiver will also power the receiver?

Exactly! Took me a while too to figure that out.Originally Posted by SeanDuffy
But that's only if you use ESC with a build-in BEC like the Turnigy Plush. There are ESCs without a BEC. In that case you have to have a separate BEC like this one http://www.hobbyking.com/hobbyking/s...dProduct=10312
