Default Regulator Regulations

There are so many regulators on the market, its confusing me on what is needed. I'm building a Rappy SE with Align 620s. What AMP draw should it be able to handle? I like the idea of having on-board glow, like the Align 2n1, but not required. Any input, or recomendations?


Thanks ahead
Whiskey

Three Align servos should not draw more than 5A, add the gyro and tail servo and you should never see more than 7A. Remember that stock servo wires and the bus at the RX will only take 5A continuous, so make sure the feed wires from the regulator is a little thicker than stock servo wires. If it has two outputs it will even be better, one output for the cyclic servos and RX, with the second one for the gyro and tailservo.

A 10A regulator should be enough, just take note that ALL regulators have diminishing output capabilities with an increase in input volts, even the switching type, ie CC's new switching regulator claims 20A output, but only if the input is 8V or less, at 20V input they only rate it at 5A.

In CC's press release for the CC BEC Pro, the maximum continuous current as a function of input voltage is:

16V = 15A
24V = 13A
32V = 11A
40V = 9A
48V = 8A

I have a 600n and just built a Hirobo SDX. I use the Align 2 in 1 on both. Never had any problems. The 600n runs 5 full size digital servos, an hs55 for the CarbSmart, a 611 gyro and a GV-1 governor. The Hirobo will be getting a CY ATG after break-in and probably a CarbSmart. The Align 2 in 1 will work just fine. Alan
