Chris Walby Posted November 29, 2021 Share Posted November 29, 2021 I use Maxloc or the Nexus type as the din one's IMO are not rated for the current, tricky to solder and mine (I didn't build the model) has no means of locking them together. PS - don't forget to make one wing a male plug and the other a female so you can't plug the wrong one into the fuselage loom. Quote Link to comment Share on other sites More sharing options...
Andy Gates Posted November 29, 2021 Share Posted November 29, 2021 If your radio has the facility, how about using sbus? 1 Quote Link to comment Share on other sites More sharing options...

You have me wondering how that would work on a plane with 4 servos in fuselage (throttle, rudder, elevator, elevator) and three in each wing (flap, aileron, retract) plus a light in each wingtip. Assuming the servos in the fuselage remain attached to the receiver, does it require 2 sbus decoders (one for each wing) plus 3 sbus servos in each wing (or sbus to non-sbus decoders), providing two connections to he rx to be made when assembling the plane ?

Trevor Posted November 30, 2021 Share Posted November 30, 2021 Good to see all the multiway connector solutions here. Another approach that I've found useful on a couple of models is simply to put one receiver in the fuselage and another in the wing, so you only need a power connection between the two. Clearly this can become a bit expensive for multi-piece wings! Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted November 30, 2021 Share Posted November 30, 2021 I do not fancy all signals going down one wire nor trying to power six digi servos from a single power supply. I have S bus available on the odd sets but have never found the need to try it and never shall. Quote Link to comment Share on other sites More sharing options...

I personally use Mpx connectors and "potted" with hot glue they have always proved very reliable for me, no failures in over 15 years of use. I agree they aren't the easiest to solder, but few RC connectors are and once you get the hang of it I never seem to forget! Edit - For a really neat job you can use the Winkler moulds available from T9 - pricey but they do give a very consistent result...

Geoff S Posted November 30, 2021 Share Posted November 30, 2021 I've only rarely used the otherwise excellent Mpx connectors mainly because of the lack of a cord grip. Those moulds from T9 look like they overcome my reserve, despite the price - which isn't prohibitive once it's spread over a few uses.

John Lee Posted November 30, 2021 Share Posted November 30, 2021 Likewise I use this mould from Pichler which covers most popular plug options. Here is the result with the Emotec/Multiplex 8 pin plug serving 2 wing servos + lights. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted November 30, 2021 Share Posted November 30, 2021 Do you just use hot glue with these moulds or is there a better option? I've soldered a lot of XT60 plugs and sockets and relied on the heat shrink to relieve the stress on the solder joint. Can't say I've ever had a problem after many operations, perhaps because both joint and wire are rather more substantial than servo connection ones.

John Lee Posted November 30, 2021 Share Posted November 30, 2021 I've only ever used hot glue which sets in a few seconds and works well. In the case above I used a black stick to match the connector just to finish it off nicely. Quote Link to comment Share on other sites More sharing options...

Martin McIntosh Posted November 30, 2021 Share Posted November 30, 2021 Puzzled. Why would you want to use a MPX connector for those apparently HD cables? Quote Link to comment Share on other sites More sharing options...

Fuselage servos connected to the Rx - correct. 2 sbus decoders (one for each wing) - correct. 3 sbus servos ? Not necessary - normal servos can be used depending on the sbus decoder in use. 2 connections to the Rx when assembling the plane - not necessarily as I believe sbus decoders can be daisy chained so you could join the decoders in the wings as the wings are put together leaving 1 connection to the Rx Quote Link to comment Share on other sites More sharing options...

If you buy a Multiplex model you'll see in the instructons they often show a 6 pin green connector being used on a lipo. Why I'm not sure - it must be more long winded to solder and it can't have the same contact area as a dedicated power type plug (XT60, EC3 etc) has (they are only rated to 35A). I can only assume Mpx want to sell more of their own connectors! Edited November 30, 2021 by MattyB Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted November 30, 2021 Share Posted November 30, 2021 One use would be for a Jeti Central Box (a power distribution and receiver redundancy solution) where these are the input connectors provided. Quote Link to comment Share on other sites More sharing options...

Yes, that was another hilarious Frsky own goal - they were so busy copying Jeti they forgot to check whether or not the connectors were the best option for the global market. They had also only half finished the firmware at initial release with predictable results… ? Quote Link to comment Share on other sites More sharing options...

dave windymiller Posted November 30, 2021 Share Posted November 30, 2021 (edited) Ive just bought these for my turbine powered f86. They will trap between fus and wing for aileron & flap and will align as wing inserted. Intentions are common up both servos +ve on 2 pins, same on -ve and 2 connector pins for each servo signal. Cables ends then buried in epoxy blocks (shape formed by tape). Edited November 30, 2021 by dave windymiller Quote Link to comment Share on other sites More sharing options...

Nick Somerville Posted December 3, 2021 Share Posted December 3, 2021 Received my connector today ordered from Gashangar and disappointed to find that it wasn’t as expected. It has two pairs of three wire leads but the other 4 are all two wire leads and the block only has 14 connections. Not sure what the purpose of it is. 1 Quote Link to comment Share on other sites More sharing options...

Martin Harris - Moderator Posted December 3, 2021 Share Posted December 3, 2021 If you look at Nick’s original photo with the benefit of hindsight, you can see it is the same. I suppose some work with a scalpel tip could allow you to release and rearrange the servo connector pins to use them for 4 servos/retracts and leave a pair for a light feed. Although a little less convenient than a simple plug in solution, this allows you to use the original plugs without having to re-crimp or solder any connections.
