Gidday,

I am interested in what is the correct or preferred connector for the small wires in the RayAllen Servo wire bundles etc., the small dia cabling of many devices. I’m sure there are some better than others, but I currently don’t know any, albeit a ACS catalogue could narrow it down. So far, I have tried D sub terminals, as they are easy to get and easy to solder. Should I stick with them??

regards

Tony Renshaw

Yes Tony , I mounted a D socket on to the servo body so that I could remove 

it for service in the future, its a bugger of a place to get at. The other 

end tails go straight to the switch and indicator.

Best of luck

Richard

Hi Richard,

Other than the multi core wire of the servos, is there suggestions for connecting the very thin wires together, other than D sub connectors.

Regards

Tony Renshaw

Hi Tony 

 	I used shielded wire and stagger soldered the connections and left a service loop that allows easily access and replacement if ever needed through an inspection hole and if it fails on a trip far from home, I marked the wires so I can jog to neutral trim with a 9 volt battery: 

 	http://www.europaowners.org/main.php?g2_itemId=30484 

 	I used nutplates and Allen screws that will allow removal of the servo with a ball end Allen. 

 	If you absolutely want to use a connector, Bob from Aeroelectric has directions how to use a D-Sub connector with no housing, strain relieve the wires with some clear goop, something like Shoe Goo or a name with 6000 in it, don't use stink silicone it can corrode things, no stink is probably OK although Shoe Goo is pretty good stuff, then use a piece of heat shrink to hold the two halves of the connector together.

Tony…At that stage of the build, I was not comfortable w/ using D sub terminals and questioned my ability to disconnect them w/ one hand…I used this AMP connector w/ the larger, crimped pins…I also floxed the nuts on the back face of the bulkhead which hold the servo in position, though I’d use nut plates were I to do it again…Fred

I have just tried to replace my servo before discovering 

that the fault lay in one of the connectors in an awkward 

position behind the panel (actually a snapped wire going 

into a crimped pin). In speaking to the guy at Ray Allen, 

he was v. Surprised to hear that the servo had packed up, 

and implied that they just don't do that even after as 

many hours service as mine - and he proved correct when I 

released the wiring and retested it. My advice would be to 

solder the wires at the servo end to the same coloured 

wires in the multicore cable also supplied by Ray Allen, 

supporting individual joins and the whole bundle with 

heatshrink and also supporting the cable near to the 

servo, etc. I feel this is less likely to cause problems 

than a connector, and in the very unlikely event that you 

do need to replace the servo, replacing soldered joints is 

no great issue. Incidentally I have a brand new servo 

still in its original sealed pack should anyone need one!

Bob,

Thank you for taking a close look at my build photo…as I read your post, you’re asking if I have shortened the plastic clevises.

From the XS build manual, I read:

 	  Quote: 	
		  Cut off a 32 mm (11/4“) piece of the threaded rod and screw on the two plastic fork-ends until they are butted together

	




I read nothing about shortening the plastic clevises; rather, it appears to me that the intent of the instructions is to ensure that the shortened length of threaded rod allows for the plastic fork-ends to abut one another.

My top has been bonded on for several years, so you raise a possible issue of some significance.

Have I missed a bit of Europa-lore which never made it into print in the manual?…or what?

All comments appreciated,

Fred

Hi! Fred,

Better check with another “oracle” then but I remember first sizing the clevises and then making the threaded rod to fit. What you need to do is operate the trim motor to it’s full travel position both ways to ensure that the lever they are driving doesn’t foul up on the root of the clevis before the motor stops.

Sorry if I may have caused some confusion but I recall needing to size the clevises first and yours are clearly to be seen untouched? Of Course all these years on things may have changed. But it is interesting no one else has commented?

Hi Fred

I think Bob might be correct.  From memory when i installed mine i had to shorten the fork ends. 

The reason being when connected to the bellcrank and you operate the servo  it can bind in one direction. 

You will know if its binding as it labours near the end of the travel. 

This check is part of the final checklist, to ensure the trim servo moves through its complete range with no binding at all. 

Hope this helps

Kind regards

Donald

Don…not exactly what I wanted to hear, but I thank you nonetheless for responding to my request…after poking around a bit, I don’t see any insurmountable problems to trimming my plastic clevises at this late stage of the game.

Though I’m wondering…when you “shorten(ed) the fork ends”, were you trimming literally the ends of forks thru which the clevis pin fits?…or did you shorten what I’ll call the base of the clevis, i.e., the opposite end where the two clevises abut one another after being brought together by the threaded rod?

Good luck with your paperwork…I’m rather envious,

Hay Fred,



Don’t fret.  I did mine just like yours:

[img]cid:1D08E18E-513A-4570-A8E3-43E8A951043D[/img]



It works just fine.  That’s the way my instructions said to do it:

Trim servo

Step 5

Unpack the MAC electric trim servo and study all the instructions.

Cut off a 32 mm (11/4“) piece of the threaded rod and screw on the two plastic fork-ends until they are

butted together.



There must have been a change in the instructions somewhere along the way.

I have just fitted my trim motor two days ago so this was good timing! so i did per the instructions and cut off the required tread and butted the plastic forks together. I then found that when the motor was fully extended out it would catch or rather bottom out on the cut out of the bell crank support. i extended the cut out after speaking with another builder and this allowed full travel of the trim motor.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Tony,

 Your build experience will be enhanced by learning how to do DSub  connectors properly.  Pins and Sockets may be purchased at very cheap  prices (even in gold plated connectors as I use).  

  

 I use Allied Electric (alliedelec.com) as my primary supplier.  All  your avionics uses D subs.  Garmin supplies and prefers the mil spec pins  and sockets, but many others are available.  I use Tyco (TE  Technology) or Amp primarily.

 Tools you need are:

 A crimper  (I use an Eclipse pro grade one, and my friend uses a Quest  technology ratcheting type for open crimp type pins which crimp the wire and  insulation for a great connection as well as my megabuck  one.)        (I use a Quest Tech for my  barrel pin connector crimper.)   Even Radio Shack has pretty good  tools.

  

 A D sub pin and socket extractor tool will be necessary.

  

 A good wire stripper.

  

 And you will find 9 and 25 pin are the the most common used in the  aircraft.

 Connectors are only a few bucks, hardware a couple more and pins come in  sizes from AWG 30 wire to #18 and run about $.030.

  

 I also like circular connectors for my through the firewall and  airframe to panel hookups.

  

 More tools and fun gadgets.

  

 After all, you built it, you can maintain it far cheaper than hiring  someone.  But you need to do the study and practice.

  

 If I run a wire anywhere, it terminates in a plug with a bit of a  maintenance loop or S turn to facilitate maintenance.  If it is electric,  assume it will fail.  Especially make sure you have connectors that are  easy to latch where it is difficult to get to or work.  Manufacturers make  all different kind of connectors and hardware.

  

 I do deviate from the book when it comes to inspection holes.  I  believe an inspection hole must be big enough to work in, not just look and  scratch your head to try to figure out how to fix something using tweasers and  forceps while looking backwards through a mirror.

  

 Enjoy Building

 Bud Yerly
