  • Single "Multi" plugs for Wings

    I've never used single plugs for wings and want to venture into this with the new ASH31.

    Which are best? sub d like the ones from Chief?

    Or, Multiplex like these?

      Not sure about the wiring but for 3 servos would I'd need the 1x6? Especially since one would be using a different voltage or a 1x9?

          +1 Gunny! I used to make my own leads but I have better things to do with my time (I'm messin' with LenB!) so I use these, now.

        I like the multiplex 6 pin plugs with two servos on each plug. You can run more if you use common ground and power but the soldering gets kinda crazy at that point. And I found these molds that allow you to inject hot glue, forming a solid grip that also reinforces the solder joint. Mark and I have both used them and you are welcome to if you go that route. I glue the fuselage side of the wing root connectors in place and leave the wing side connectors loose so that I have to plug them in. I read somewhere that this reduces the chances of breaking a pin on the connectors.

        I also had a Shadow TD plane with the sub d style that worked fine.

          1x9 for 3 servos.

            As Victor says the Multiplex 6 pin works, but the soldering can get a little tedious. I have been using them on my Ka-8b for two years now with one side fixed to prevent side loads on the pins. They have good pin contact, so connection grip is not a concern to me.

            When planning my Ventus wiring I chose them again and use two per panel, being a 4 servo wing per panel. I could have used one pair per panel, but branching the power would have been a little messy, IMHO. Also, Multiplex claims the pins can handle up to 5 amps, IIRC. That should accommodate most current servos with separate power sources easily.

            The dies Victor linked make a nice clean assembly once you get the hang of using it. Attached is a picture of the wing root wiring of my Ventus. BTW, the fuselage harness will have the expando on it when I determine final length.

            Merry Christmas everybody. OOH, and a shameless plug here don't forget about the Apache Pass Aerotow next year in April!

              Hansen Hobby 1x9 locking connectors

              Team PowerBox Systems Americas ............You can't buy happiness. But, you can buy a sailplane and that's pretty darn close.

                Powerbox has a great selection of harnesses using their wonderful wire. They come already soldered and molded with both Multiplex and DB connectors. I had custom lengths made for our long glider wings. Duralite Flight Systems has a nice selection on their website.

                Merry Christmas

                  Another vote for the Hansen Hobby connectors. I use them on all my gliders. Crimping and wiring is the most relaxing part of assembly for me now.

                    Hansen Hobbies is where I usually purchase my wire and connector supplies...good quality stuff. For my assembly the configuration of the Ashlock bodies I could find readily would not fit through the wire loom hole in the fuselage. So, I needed a better form fit in my application, AKA two MPX connectors.

                    I plan to use the Ashlock (ED-102 or Hansen Locking) style of connectors for the servo connections in the servo bays of the wing, although I have in the past just tied a loop around the mating bodies with button thread. Simple to do and inexpensive. Keeps them from getting loose, but I've never had a problem with it before. My belt and suspenders mind set again. OOH, I also have multiple airplanes using the Sub-D style and they work well too. There are many configurations of Sub-D's, some with power pins rated to 30 Amps. Mouser Electronics is a good supplier of small quantity electronic materials.

                      I use these from Emcotec......MPX style with a neat “handle” that solders to the pins and makes it way easier to solder servo wire to the plugs.....I’m using an 8 pin on the ASH-31 for the wings......the spoilers will get their own 3 wires since the voltage is stepped down and the flap and aileron will share their negative Terminal.
