Subject: TIG and Aileron Gap All the welds in my Piet are TIG welded then normalized. (brought to a dull cherry color with a torch in a larger area, and allowed to air cool in still air) Didn't know this till' I had the entire engine mount primed, painted and mounted !!! Guess what ?? It came off, got stripped, and each joint normalized with a torch. Good advice coming down the pipe from you welders out there. Earl Myer's Sky Scout incorporates an aluminum 6 foot piano hinge on his ailerons. An excellent gap seal AND hinge arragement. Not the cheapest stuff to buy, but you will never have to fuss with gap seals again. How much wood to shave off the loins to accept the hinge ? I just mounted it flush with the aileron spars and flush with the top of the ribs.....so having a wood trailing edge I just sandedthat down to match the rest of the wing trailing edge lines.

There was no safetydiference in putting the hinge facing down or up, the travel of the alerionswas the same...The problem was that there was LESS alerion response of the plane! It wasnothing unsafe at all, only it tooked a little longer to response and alittle more travel (only the pilot/owner will notice the diference). Wecouldnt found a "logic" response other that it needed to "disturb" theairflow to work ok.Hope this helps,SaludosGary GowerPS The Teman Monofly is a two seater of the 80's with a 503 Rotax and issimilar to the Quicksilver GT 500, in fact we nicknamed this one "ThePoorman 500" it cost him 6,000.oo Dls incluiding restoration. ________________________________________________________________________________
