Wire 2 BEC outputs in parallel ?
 
Does anyone see a problem with wiring the output of 2 BECs in parallel to double amperage?

No problem, just make sure they are rated the same.

You will get more than what one would put oiut, but it won't double. You'll get somewhere around 75-80% more. The reason for this is due to how the feedback works in the switching regulator.

stand alone bec- sure
esc's built in bec- I thought this was bad.....
Brian?

Yeah, I personally wouldn't parallel BECs at all. It depends on the design of the BEC circuit really. I've had a BEC (can't remember which) get really hot if the output was fed with even a slightly higher voltage.

If you have a high servo load, I would just run a seperate BEC on just that device. It's just a matter of isolating the red wire, but the ground and signal wires need to be directly paralleled.

thanks:intello:

Thanks.

Any thoughts on how much current an AR6200 RX or a heli gyro would draw?
