Cockpit noise level
I am trying to reduce the wind noise in my Duo Discus. I've tried
adhesive-backed foam and weather-stripping with limited success. Anybody have a "Perfect" or even "pretty good" solution to getting the canopy to fit tight enough to be quiet but loose enough to open and close without too much hassle? Thanks, SF |

Cockpit noise level
Two place Glider canopies make twice as much noise. I have struggled with that issue on both of the ASH 25's I have owned. Open cell weather stripping works the best as it compresses down nicely, but it moves in hot weather and has to be replaced often. This year I discovered some slightly denser open cell sticky backed foam tape at a hobby shop. It is white and about 1/4 inch in width. It held up all last season and look like it will last at least one more year. I think it is called wing mounting tape. On the ASH the noise seems to come mostly from the back of each canopy.

Thanks, SF Two methods I know of: 1. Mylar tape on the outside of the canopy, similar as you would use on the aileron. Seems OK for a private glider, tends to be prone to damage in club gliders. 2. Use silicon sealant (or similar) to reduce the gap between fuselage and canopy. Cover the canopy side with cling foil, apply the silicon sealant into the gap in the fuselage and then close canopy until sealant is cured. Be careful not to use too much of the sealant. -- Peter Scholz ASW24 JE |

Cockpit noise level
I've been pleased with the wind noise reduction produced with
SP-FT132 sealing foam tape around my Ventus canopy. Unlike hardware-store foam tape, its a closed-cell foam, and very thin, only 1/32 inch thick before compression. It's black, but I put it on the canopy, not the fuselage, so its not typically visible. Available from several places, e.g. http://www.aeroinstock.com/products/SP- FT132/25/4173/product_detail/index.html At 06:12 10 October 2013, Peter Scholz wrote: Am 09.10.2013 20:18, Tom Bjork wrote: I am trying to reduce the wind noise in my Duo Discus.
