Parkspeed Posted October 3, 2015 Share Posted October 3, 2015 Greeting gents, Multiplex wing looms seem to be the trend these days, do 9 pin serial plugs get used? I'm thinking of using them in my ASW wings to connect the surfaces and keep things tidy, any of you guys use them? Cheers Simon Link to comment Share on other sites More sharing options...
oipigface Posted October 3, 2015 Share Posted October 3, 2015 It doesn't really matter what you use as long as every time you plug it in, it connects and stays connected, until you unplug it. MPX plugs are compact and easy to install as long as you have minimal soldering skills. There is a continuing debate about whether it is best to secure plug or socket, both or neither to their respective components. I have recently taken to fixing one, and leaving the other on a fly lead. Both need their connections to be well potted with epoxy, and fly leads are best constructed with a few inches of heat shrink over the leads to make them more resistant to damage.

Jef Ott Posted October 3, 2015 Share Posted October 3, 2015 (edited) I was having trouble finding a source for the RS232 9-pin serial port plugs and sockets, and noticed that Maplins sell serial extension leads (they were on special a fortnight ago so £2.20 bought 1 off 2m lead including one plug and one socket). The wires already installed in these leads are (IMHO) not capable of carrying the loads a 4-servo wing will proffer. So when I do use the plugs and sockets I will need to strip them back to the bare bones first. The reason I want to use an RS232? The same as Pete - Calypso Contests. I have two wing centre panels and three fuselages, and I want to be able to use both wings on the third (electric) fuselage as one wing has a camera mount and the other doesn't.There are many ways of skinning a cat however, and I really like the Deans 4-pin units sold by ElectricWingMan https://www.electricwingman.com/deans-micro-plug-pair-red-polarised-4-pin-1242.aspx My Organic has one of these and a normal Futaba servo plug/socket. The 4-pin job just does the aileron connections and the Futaba connector joins directly to the single flap servo. Some of the plugs and sockets take a lot of insertion force, which can lead to jerking while disconnecting (which might cause secondary damage to wingskins etc.), the Deans Micro plugs require a sensible amount of tension to separate them.On two-piece wings, I have used the 4 pin plugs when assembling scale slope models with one plug and socket in each of the wing half to fuselage joints.Jef Edited October 3, 2015 by Guest Link to comment Share on other sites More sharing options...
Parkspeed Posted October 4, 2015 Author Share Posted October 4, 2015 Guys, Thanks for the info, a wealth of experience on this site Bob How Repaired my fuz ( top job ) after I went in at White Sheets a while ago I'm just waiting for the fuz back from the painters, serial plugs it is then, I'll have to root all wires to one point and install, browsing through flea bay there's a massive choice to choose from. Pete, it's blowing a gale this Wed up Ivinghoe, may see you there. Cheers Simon 1 Link to comment Share on other sites More sharing options...
martynk Posted October 5, 2015 Share Posted October 5, 2015 I use Ashlock connectors from Fighteraces.co.uk http://www.fighteraces.co.uk/products/ashlock-connectors/That are excellent, I have tried 9D connectors and not been overly impressed, too fiddly to solder and they are not really designed for this type of use Link to comment Share on other sites More sharing options...
chiloschista Posted October 21, 2015 Share Posted October 21, 2015 Can you crimp the Ashlock connectors with a usual 24-30AWG crimping tool?Thanks,Ric Link to comment Share on other sites More sharing options...
martynk Posted October 21, 2015 Share Posted October 21, 2015 I use the standard cheap HobbyKing crimping tool. Not the best but once you get used to it, it's fine. Supports both thick and thin servo wires Link to comment Share on other sites More sharing options...
chiloschista Posted October 21, 2015 Share Posted October 21, 2015 Mhmm, those really seems the same as Hansen Hobbies ones, just at a fraction of the cost and with quantities discount.I already bought hundreds of connectors from them: great service.

martynk Posted October 21, 2015 Share Posted October 21, 2015 Yes - they look identical. Also a PCB mounted version which could be useful... Link to comment Share on other sites More sharing options...
