Hi Guys After reading the posts regarding aileron spars and the like, I thought it appropriate to let you know of another way to do it without using wood at all. As some of you know, I am involved with building Whisper motor gliders and as the designer is a friend of mine I was lucky enough to see how he built his. The wing of the Whisper is built much like the KR except that it has only one really strong glass spar. Where the ailerons were cut out all he did was 1) before glassing the wings he marked the aileron cutouts on the foam with a fine marker. 2) Placed a strip of peelply about 1.75" wide centred on these cutlines. 3) after wingskins have cured the ailerons were cut out on these cutlines leaviing half the peelply on the wing and the other half on the aileron. 4) The peelply was then ripped out takink with it most of the foam between the skins to the depth of the peelply. 5) After sanding the foam smooth the "C" section was then glassed with BID at 45deg. 6) The upper skin which was to receive the extruded piano hinge was thickened by adding extra layers to the top skin inside the "C" section untill the hinge no longer protruded above the wing contour. After curing the hinge was fastened with countersunk AN rivets (I think). The aileron was given the same treatment. To remove the aileron, the pins were made removeable. Since the ailerons on the Whisper are only slightly longer than the KR's and the prototype Whisper has by now clocked up around 200 hours I see no reason why this method can not be adopted on the KR, mine will be done in this way. Comments?? I do have a picture here somewhere if anybody is interested. Regards Dene Collett KR2S builder South Africa mailto: dene.coll...@telkomsa.net
