Wing to fuselage servo connections, what do you use?

I've fiddled around a bit with dual servos in a wing being connected to the Rx both at the same time using a small 4-pin Deans connector. Any other ideas?

How about 4 and 6 servo wings? What do you use? Does someone make something just for this purpose?

4 servos a wing = Multiplex 6pin connectors: http://www.soaringusa.com/products/p...ategory_id=352

4 + servos a wing = DB9 connector

I have been using the gold plated RS232 / DB9 connectors from a PC store. People warned me that they won't last and only have a connection life of 100 cycles. They are not self cleaning and so the contacts could get dirty over time.

So far so good but just to be sure i won't have any problems in future i am changing over to what the Germans are using. With thanks to Heiko for sharing this information!!!

You will want the gold plated RM 2.54 mm size and 2 wide strips. Cut them down to how many pins you need (8 for Avionik B wings). Note that these connectors have the same spacing and pin design as most RX'es.

Don't think they are in the USA but i am aware the USA team pilots use the polarised Deans 6 pin connectors?! They are equal quality or better, just no more then 6 pins.

Or if like me you hate soldering to tiny little plugs and prefer Crimping.

http://www.thunderboltrc.com/ashlok/AshlokInfo.html

You can go from 1 to 6 servo connectors & once you have bought your crimping machine you can then also make all your own extension/servo leads as well.

The Crimper and Ashlock connectors are probably one of the most useful tools I have bought.

Deans 4-pin for 2-servos,
MPX for 4-servo.

Never had a 6-servo, so MPX work for me BUT I am considering switching to DIN for future models, and making them plug in "automatically" (too much push/pull force required to do this with the MPX plugs)..

I've used Multiplex, but given a choice on future models I'd use a 9-pin D if it fits. The Multiplex are smaller. The quality is better on any D connector though.

P.S. D connectors come in several grades from 'nasty' to 'bombproof'.

I've never used D connectors because when I looked (many years ago) the specifications all indicated that they were manufactured for 100 or so insertions only...ie, not exactly a tight fit after time. So can you point us towards a 'bombproof' one please?

I bought an absolute that was built with a serial type connector for wing connector.. The wings were joined (not 2 piece). You put the wing in place, put the bolts and ready to go! not sure who did this but it's beautiful and hasn't failed after several years of abuse..

I did something similar with my Absolute, but I used MPX connectors. When I plug the two wing halves together they're joined via an MPX connector. There's an additional MPX male connector in one of the wings. I didn't make it plug & play at the fuse, though.

I wanted the ability to have a little slop on that connection to allow more room for batteries, and to not stress that connection point.

Came out pretty good!

Joe,

Deans does make connectors with more than 6 pins.

The Multilpex plug is hard to beat regarding servo installation. Here my Kamelot:



Hope this helps
