Here are three images of my solution to mud daubers, that is still in beta testing, as I have yet to have any of them show up. But they will shortly I am sure. I have come to the conclusion that they like to pack their prey into little holes, so I have provided them with some external holes made out of straws, which were wraped in dark tape and cut in thirds on the band saw. Dark tape because I think most of the holes they find are some what short in length and dark inside. I used bailing wire to support them whereever I thnk the bugs will enter my plane, like at the wing end, ele end, engine openings, etc. When I catch several I will update, but I may have too small of diameter straws. I dont know what actual size hole they prefur. Anyone???
The last image of the wingtip mod I did last January is a preflight inspection window of the aieleron counterweight area. I had a flight last fall where after landing, I lost all right aiel control because of a massive, very hard dauber nest came loose on landing afrom the rear side of the outboard spar and blocked the downward motion of the counterweight.
The beta testing now underway will tell me if I need to increase the straw size, or go to plan B, which hasnt been hatched yet!!
