I noticed this by grabbing the end of the wing and moving front to rear. W26C is the barrel of the wing rear pin socket assembly. I have inspected tie bar and the mounting of the socket assembly and everything is in order. I am assuming that this is normal since the W26C barrel is free floating fore and afte and is retained in place by the 3/16 hex socket machines screws that fix the whole assembly to the fuselage. Am I right? thanks Will William Daniell LONGPORT +57 310 295 0744 ________________________________ Message 2 _____________________________________ Time: 09:43:56 AM PST US Subject: Europa-List: Re: W26C From: "JonSmith" Will, comparing notes rather than any suggestions, mine has an identical movement in the wingtip; a noticeable fore and aft movement of free play. Its in both but a bit more on the starboard side. I assume that its a touch of play in the pip pin where it fits into the wing pin and the W26B/C mounting assembly. Mine has always been like it and Ive always assumed it to be normal as I think that there must be a tiny bit of play in a removable pin which will appear magnified out at the wingtip (the wing makes a long spanner!). When I move the wingtip back and foreward I can see the gap between the wing fairing and the fuselage side adjacent to the pip pin opening and closing slightly in accordance with my movement which makes me think that the play is in the pip pin itself. I dont think that the play is caused by the W26B barrel moving back and forwards. On mine the tolerance between the socket housing and the cheeks of the fittings body are very tight, the barrel is held to the socket housing by locktite and the pip pin holds the entire assembly together regardless of the loctite when its rigged anyway. Like you I am 100% confident of the integrity of all fittings in that area. I think its just a bit of slack in the pip pin allowing the rear wing root to move in and out from the fuselage side (slightly) rather than the wing root sliding fore and aft. I would be very keen to hear from anyone else with more information on it!

I would de-rig the wings and check the integrit y of your spars, spar wing sockets, and spar pins. There really should not b e any movement at all!

I agree and might have over exaggerated the amount of movement in my description - its only small and I can only think its a touch of natural play in the pins; mainly the pip pins but possibly the main wing pins too. I trailer and rig mine every time I fly so always see it derigged. Everything is totally sound and correct. I remember in the build (well, the weight increase mod) that the main pins were always quite a slack fit in the bushes, especially the main pip pin which I seem to remember is a tad smaller than the temporary bolts supplied for build purposes, so if nothing else this must introduce a touch of movement in the system. I also remember some years ago when thinking about this very subject, walking around an LAA rally and having a surreptitious (and very gentle) pull on a few other peoples wingtips and all the ones I tried had small bit of fore and aft movment in the wing tips...!

The wing sockets are meant to be bonded in place so that both sockets are firmly in contact with the wing root when rigged, thus allowing no forward and aft movement of the wingtip with moderate force (because the wings are pulled inwards against the sockets by the main pins through the spars). But in practice, there is sometimes a very small gap between the socket and the root, thus allowing a small fore and aft movement at the wingtip. Nev suggested trying a stainless steel washer placed over the forward socket to shim it out. When you find one the correct thickness, it should prevent the movement at the tip. Too thick and the wings will not rig. When you get the correct thickness, it can be bonded on to the wing root with A420. But Nev also said if it is only a very small movement at the tip it is not really a problem. Regards, Keith Hickling, New Zealand.
