Rolladen- Schneider LS3A flap seals- Do they really make any difference?

I Just recently made some using this Template:
http://www.goddard.com/wipers/wiper1.pdf

They seem to be working great. I ordered some 0.040" thick Mylar which seems to work perfect. I selected a thicker material to see if it would be more robust than what I had before. The material before was quite thin and tore in a couple places. I have about 50 hours of flying on my new wipers and they appear to be holding up quite well. I may go back and re-cut them this winter just to make them about 1/4" wider, but we will see.

Hi,



it would be great if anybody could send me some information on how to build these seals (templates, dimension, material, etc).



Thanks,

You were flying contests in 1979? You must be one of those legacy soaring pilots ...:-) kk

I owned an original LS 3 for many years. Never had a problem with the seals in flight. But the wing root brackets in the factory Komet trailer would crease them unless they were taped together in a gentle curve before lowering the lid. I think I recall adjusting the brackets in the trailer to eliminate this problem. Dick Johnson's testing indicated there was some performance loss without the seals. I know of at least one owner who used auto body putty to build up a flat spot on each side of the fuselage so the butt end of the flaps could "wipe" against them (with a felt seal) and dispense with the flexible seals entirely. I watched them perform this minor modification in the hangar on a rain day at a contest back in...1979?
