Wee Duster mod for ailerons
Posted: Thu Aug 14, 2025 9:54 pm
My original plan was to have a single centerline aileron servo and use hidden control rods - much like Ed Larsen did on his aileron mod of a WN Honker Bipe. However, the central doubled rib of the Duster wing made that impractical without serious modification of the wing joint which could have led to structural problems. Then I decided to use twin internal aileron servos, one on either side of the center rib and still use the hidden control rods. This proved to be a bad idea because the fuselage just wasn't wide enough. The reinforcement pieces for the wing saddle narrowed the opening enough where two servos and the arms for them just wouldn't fit. Naturally, I discovered this AFTER cutting the servo holes in the upper decking. Good thing WillyCote hides such mistakes... 
Therefore, I opted for the typical one-servo-per-wing-half method. I crafted a new bottom sheet, extending to cover a second rib, to make a place for the servo. The pictures should, in theory, make it self explanatory. Let me know if you have any questions. It will be a few weeks before I can maiden the plane as I am in the middle of cataract surgery. Doing the fishing line hinges on the ailerons with only one currently-usable eye was challenging...
I should also note that I reduced the dihedral by half.
And the final result:
