Hi all, has anybody got any literature or website on how wing adjusters are mounted and used? I am wondering if they can be used to adjust wing dihedral and incidence on my next kit. Thanks in advance........

If you can see this butchered document, the adjuster fits into the fuselage and rides up and down on a screw. A socket is in the wing into which the pin is plugged. These work for F3A right up to giant scale. There is not too much stress on these pins and they work great.

I like to tape the root rib to the fuselage as colse to zero incidence as possible, drill the adjuster pin holes through both the root rib and fuselage at the same time. Mount the adjusters, and glue the sockets into the wing when everything is assembled.

By the way, we use the Gator units. We also use the Gator stab adjusters, giving us very adjustable airplanes.

I hope this has helped.

Thanks Mark ! The pic I attached is from gator. I am wondering why there are 4 adjusters per set? One pair for the wings and another pair for the stabs ? The stab adjusters are the same as the wing adjusters ?

Also, can the adjusters be fitted for one-piece wings ? A two-piece wing is shown in your diagram. The enigma is one piece, so I'm wondering how different is the installation method ?

For wings, four adjusters are used. One near the leading edge and one near the trailing edge on each wing panel. This means for each adjustment to a wing, each adjuster must be turned. It's quite easy. One turn clockwise on the front and one turn ccounter-clockwise on the readr, or visa versa.

These adjusters are only for plug in wings.

For one piece wings, the incidence is set by the wing saddle. I have seen adjustable set-ups, but only to dial in the design and set the final saddle shape. To make slight changes to incidence on one piece wings, most people use shims and then add a little wing seating tape. If the change is too great, then scabbing on additional wing saddle material may be necessay on order to maintain a solid mounting process.

For the Enigma, well, we have one of the finest composite guys in the world making our fuselages (he was the chief composite man for Mudry, the makers of the real CAP series of aerobats) and they come out of the mold with zero incidence every time. We use just adjusters on the stabs in order to ensure we have perfectly neutral elevator/stab relationship for horizontal and vertical line.

Mark, thank you very much for sharing your invaluable experience with us...........
