Re: Electrical question
1A is pushing it a bit, in my opinion. I usually assume 250mA per servo for no load and 1A per servo at stall. I guess in your application the chance of stalling the servo is very small as turning the valve probably isn't very heavy on the servo? But anyways, 3x250mA for the servos +50mA for the RX is around 800mA total which is quite close to the max 1000mA of your ESC.
You could get a 3A (or 5A) SBEC/UBEC to be on the safe side, and also it would be good to have that extra power if you're adding other things later, like lights, rotating beacon, rototilt, quick coupler, etc.
