Tidying up wires to the wing

I want to tidy up the wires to my wing which are currently a mess.....

I have 2 x ailerons, 2 flaps, 2 gear and lights... this makes for a lot of wires and connectors and Y-splitters.

I've seen an install using MPX connectors which can connect 6 wires.... and supposedly rated at 30A. This is a small plane.... with less than 5A on the RX circuit.

So I was think I could use a common +ve and -ve for all the wing servos power and then carry the signal to each of the flaps, gear, aireron and lights one the 4 remaining wore connections. This would give me one connector and take away a lot of the mess and hassle.

Has anyone done this? Any tips, thoughts or advice? Thanks.

I have never actually used them, the most I have had to connect at one location is three, I usually stick double sided foam tape to the connectors to form a block.

Some people use the 9 pin sub 'D' connector.

A search on, MPX connector, and on, D connector, setting the search for thread titles should find a few threads, here's one on the 'D' -

9 pin D-Sub connector source?

The glider guiders are probably the main users, aileron, flaps, brakes, etc.

I have some like that on my larger scale machines with removable wings/panels, so picked up some multi-connector bits from Hansen Hobbies booth at the Toledo Show yesterday. They basically are set up so you only need to unplug one pair at removal. As I make my own extensions this is relatively simple setup:

I am slowly converting all mine over to the Multiplex 6 pole connectors. I gang up the +ve and the -ve and use the outer two pins as the + and -. If you look closely these pins are actually marked + and -

This leaves 4 pins for signals

Yes, this is what I did and it seems to work fine.

I'm still a bit concerned that a solder joint to the MPX connector may come lose... but it is so much more convenient.... just takes a lot of guts to start cutting off the servo connectors.

el cheapo D plugs are ideal, as you can get them in a variety of sizes to suit the number of plugs etc, plus you can mount them so they auto-connect when you attach the wings.

Helpfully they have numbers on the back, so simply jot the numbers down on a bit of paper ie:

Pin Function
1 Aileron +ve
2 Aileron -ve
3 Aileron sig
4 Flap +ve

etc etc.

Its not as intimidating as it sounds and has the benefit that you can cut off the connectors for extension leads and have one less connection to worry about.

I bundled the leads going to the rx inside a spiral cable tidy, once connected to the Rx, keeps them all out of the way.

If the standard 6 pin Multiplex connector doesn't work, there is an 8 pin version as well (panel mount version is nice for wings)

I've been trying to source some 8 pin mpx connectors in the UK but no one seems to stock or import them. Same with the secure clip for the 6 pole ones. I can get them from Germany but they want 16GBP for shipping! !! - a bit excessive me thinks for a pack of 5
