Holybro 6c Mini for heli?

ArduCopter Traditional Helicopter

I’m looking for a new flight controller for my TRex 500 heli, and the Holybro 6c Mini is looking good, but I have a couple of questions:

The spec. sheet says maximum input voltage 6v, servo rail input 0 ~ 36v. So is the servo rail independent of the 6v input and not counted in the 1.5A current limit that’s quoted for ‘all other ports’? If that’s the case, if my servos run on 6v (as they do), do I feed both the 6v input and the servo rail in parallel from a single 6v 10A BEC?

The servo rail is isolated so yes, you would source it with a BEC for Servo Power. The FC power is typically provided by a power module, Holybro has a few different ones. These supply the standard 5.2V that these and other Flight Controllers like it use and sense battery voltage and current.

Thanks Dave.
