    Default kitfox classic 4 speedster tail problem

    i everybody,im now in progress to install all ribs in my vertical and rudder ..so all my vertical was done,but yesterday when i check to starting installation of rudder ribs .i found a little problem...on my construction book i have two plans ,one for speedster and the other is for model-4 1200...the problem is ....on speedster plan.they said to put a space of 2.32 at bottom and 1.52 at the top..but it"s impossible for me because the rod end at 2.32 is completly out of bushing....and on all plans he have 4 rod end and on my tail only 3....????
    maybe because is early model...??

    so for my tail the only solution i think is to trim all ribs on rudder maybe 1 inch +/-...

    any suggest will be welcome...i dont think i happen only at me...???

    Hi JF

    My manual is dated 2003, and shows the Speedster tail with 3
    bushings on the vertical. I adjust the rudder to tailpost space
    before fitting the fiberglas fairing, Tube to tube dimension has
    allways been able to achieve. Post a picture if I don't understand.

    I have a Classic 4 manual from 1994. It shows 4 rod ends to attach the rudder. Top three rod ends are part number 93004 (3/16" x 10-32 rod end). The 4th (bottom) rod end is part number 93001 (3/16" x 1/4"-28). Bigger than the top three.

    Now, in 1996, Old Skystar sent me a revised "Classic IV Fuselage Assembly" (Document P/N 10192.000). This new manual shows only three rod ends to attach the rudder. All three are the bigger part number 93001 (3/16" x 1/4" -28 rod end)

    Maybe your rod ends are the wrong part numbers.

    It appears that the bushing the rod end screws into is too short. The bushings on my classic 4 stick out about 7/8 inch past the rear of the fuselage tail post which is near even with the center of the cutout in the rudder stop tabs.

    This one has just the foam gap seal on the tail post. The rod end check nut in this picture is tight against the end of the bushing. The left end of the ruler is near as I can tell where the rear of the tail post is.
