    BTW, it you have to power a lot of servos, one of these may help: https://www.servocity.com/servos/ser...g/power-boards

      What is the best voltage setting for the Castle10? It is default for 5.1volt, but I have some planes with digital servos. Would 5.5volt be better?

        You need to search for the Voltage limits of the servos. Some are rated 6V (five NiCd cells), so can go up to about 7.5V, the full charge of a NiCd pack, and others say 4.8V, so maximum 6V. Newer servos can be powered directly by 2S LiPos.
        I generally use 5.5V, just to make the servos a little more responsive, at the expense of a bit more current to the analog servos.

          Expert opinions please I'm working on a plane , and this is my first where i'm going to have a seperate BEC.
          I have all my parts now for my Hanger 9 Spitfire. Ready to do my soldering/wiring of my ESC and BEC. And start assembly of this Spitfire
          Question on wiring. Should i NOT deviate from the provided wiring diagram? OR....as in the pictures i took, wire my ESC & BEC in the way i've laid it out in the pics? Pic 2 & 3 are the same configuration. As you can see, going 12s.

          Thanks,
          Lon

            Lon........Don't deviate from the drawing. The way you have it laid out on the table is a serial setup for 12S which is fine so far until you jam that down a 6S BEC.
            In the drawing the BEC is only getting fed by one (1S-6S) battery.
