Re: [RCSE] Plug-in wing wiring connectors: good, bad, ugly?
Don't know Stevebut the action of clipping a tip is very similar to the action multiplex recommend to remove the wing from the connectors!! good point though I prefer to use the little red wedge.

Get a pair of sub-D connectors with solder cups, like those here: http://img-europe.electrocomponents.com/largeimages/C447702-01.jpg Cut away the metal shield and cut seven-pin blocks from the connectors. Four pins will be used for ground, power and two servo signals. One pin will be the key pin to avoid reversing the plug. Two pins at the ends of the blocks will be removed and replaced with short steel rods that are glued to the female connector - those rods will carry the mechanical loads. Female connector will be glued into the wing. Steel rods must be thick enough to keep the connector firmly in place. regards, Arne RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Plug-in wing wiring connectors: good, bad, ugly?
I don't advise this per se, but the connector system I employ at the tip panel to center panel intersection has a detent-based locking mechanism. For all but the most spirited of flying, it works great. Just slid the wing on and go. I dislike tape.

On large scale sailplanes I have an option where the fuse-mounted connector housing is spring loaded. If the wing is displaced, the connector housing compensates. Pics available. On F3x ships, the key is to use appropriate length pins in the first place to allow for some disassociation.

Re: [RCSE] Plug-in wing wiring connectors: good, bad, ugly?
The only advice I would add is that if you have a wing that pushes onto a joiner that goes through the fuz, rather than a centre panel which bolts on, it is safest to make only one side fixed. i.e. fix the one connector in the wing and make the other one from the fuz loose. The advantage is if you catch a tip on a aerotow or other launch and the wing is pulled out a fraction then the connection does not become detached. The same would apply to tip panels. I have known someone loose all surface controls on one wing from clipping a tip. I mainly use the multiplex connectors and have had no reliability issues with the connectors, a wire has pulled broken off the back of the loose connector though so I now epoxy the wires at the back of the connector after each individual wire has had heatshrink applied.

RE: [RCSE] Plug-in wing wiring connectors: good, bad, ugly?
Yup, mechanical alignment is important for any PnP system to operate to their potential. I supply instructions and pics to take the guesswork out of the equation. A little patience goes a long way. To add validity to plug-and-play systems more and more aircraft manufacturers are offering this not as an option, but as intergral to the design of the aircraft. The Pike, NYX, Artemis, and the Icon come to mind. As John points out, DB9 and DB15HD's have been employed in large scale sailplanes for years. My 6 meter Ripo DG-800 came stock with them. My 6 meter Fiber Glasflugal ASW-22 came with them (uninstalled) back in 91'. Keep in mind that not all DB-style connectors are created equal. The units you get from Radio Shack are not of high enough quality IMO. There are DB-6/15 which have pin/socket designs meant for lots of plugging and unplugging. I can supply PN's if you are rolling your own.

EMM supplies all LET models over 1/3.5 scale with factory installed pre-wired, pre installed plug and play wing connectors and fuselage wing wire harnesses. On the out put/input ends, We use heavy duty JR/Graupner wire, add JR gold plated servo and rx connectors. Mini Sub D wing to fuse connectors have proven very reliable in actual use... In the field tested by Pete Goldsmith who has flown his LET DG-800s over 900 flights at air shows and scale events around the U.S. In plain English, it is important to locate the plugs for proper strain relief, referenced "mechanical" I assume by Simon.

Re: [RCSE] Plug-in wing wiring connectors: good, bad, ugly?
There is no downside. A failed connection is more likely to occur if you are forced to manipulate connectors and wires every time you set up and break down for the day. In systems where the connector housings are mounted, the leads stay put. This creates a significant increase in safety, as the electrical connection is made automatically. No longer can one forget to hook something up before the first flight of the day. Most folks are not aware how poorly the connectors that come with our radio systems conduct electricity after 40-50 connections. They were not designed for constant plugging and unpluggging! I continually search the connector industry (there are literally 1000's of designs and configurations) for connector systems that work well in our models. Some of the criteria: - Excellent current carrying ability (read low resistance). - High cyclicability (read higher than average gold/bronze content to allow lots of plugging and unplugging using spring contacts and pin assemblies that have been designed for this purpose). - Integral mounting configurations that make it easy for the modeler to install. It's a win-win situation, just ask those who already employ (true) plug and play systems. There are many options available to tailor a PnP system to meet precisely the requirments of a particular aircraft, be it tiny to large scale, F3J/B/F, F5B, IMAC...anywhere a reliable high integrity electrical harness is required. At present there are two operations who can supply you, Hoopes and PnP Systems. Each type of aircraft has different electro-mechanical demands, you need to choose a system that can be custom built to meet those unique demands.
