Hello all,



I would like to utilize some type connector/plug inside the fuselage at the

wing root locations for all of the electric goodies in the wings.  This

would allow me to complete all wiring in the fuselage and would also

facilitate wing removal and install later.  Below is my list of equipment

and other found in the wings:



	--strobe/position lights

	--landing/taxi lights

	--aileron AP servo 

	--heated pitot 

	--NAV antenna coax

	--AFS AOA tubing



Any suggestions on the best way to handle the above would be appreciated.



Thanks!

I used a molex connector for the electrical stuff and the AOA kit came with barbed fittings on AN4 caps - I got an extra set of the barbed AN4 caps for the wing-root disconnects.  my Pitot/static lines are AN4 fittings too.

Wade,



First of all, once you understand and experience installing your wings ONCE, 

you will understand that they will never come off again...



Second, adding connectors is to be avoided, period.  There is no reason to 

cut a perfectly good wire, or 10.



Third, many, many builders, including myself, have routed the wiring after 

the wings were installed allowing for a clean installation with no chance 

for static or shorts.  I personally installed the wiring in the wings 

leaving about 15' of wire at the wing roots.  After installing the wings I 

routed each wire through the fuse to where it terminated.  Took me about 2 

hours to connect both wing wiring.

Hi Wade"I would like to utilize some type connector/plug inside the fuselage at the wing root Any suggestions on the best way to handle the above would be appreciated."I made a custom pneumatic and electrical connector. Pneumatic is a mutilated Winter connector (gliders), I purchased from Cumulous soaring, and the electrical is my favorite connectors I use for electric models, either Anderson power pole or Sermos connectors, www.mcmaster sells them under I think modular connectors. Here are some more details what I am using on my Europa monowheel:http://www.europaowners.org/forums/gallery2.php?g2_itemId=31838I am using a very thin bungee also purchased from www.mcmaster.com to teather the connector where I want it. There are a few styles of contacts for the same housing. For the pitot heat, even though  contact is rated for more than enough current, you need to make sure that contacts are clean and have enough tension to get that rating, with models that draw over 20 amps I always parallel a set of contacts and have never had a problem (if i get a bad connection besides motor quitting i lose control) if it were I plumbing pitot heat i would parallel two contacts for each connection.

HI Wade-



My plan for wing wiring connectors to facilitate wing removal is to lay the

groundwork for the connectors without actually installing them.  This

includes running all the wires through an accessible area near the root,

putting a service loop in the bundle, and labelling all the wires twice

with the labels about a foot apart.  This way there will be no electrical

or mx issues with the connectors.  Should I ever have to remove the wings,

I can just cut the wire bundle between the two bunches of labels and

install a connector prior to reinstallation of the wings.  Likewise the

pitot line. 



FWIW-
