    Extend a wing
    I posted this on the Yahoo forum, but I did not get any takers;
    I have two short-wing Avids. One is a speedwing, and the other is apparently a clipped STOL wing. Both are 106 inches long at the spar.
    Both have 1 1/2 inch washout at the tip rib.
    I am not impressed with the flying characteristics of either one. I have a wing extension kit that was intended to extend a speedwing.
    Would I be better served by extending the speedwing, or the clipped STOL wing? Ribs are not a problem, I can make ribs.
    What is the experience with extended speedwings? Is it worth the effort.
    Thanks, Bob

    No, I'm Bob McCAA...another one of them heathen Scots.

    The difference between Avid gear and Kitfox gear is that the Kitfox axle is directly below the front gear pivot, and the Avid axle leads by about 3 3/4 inch.(on the tall gear)


    I think the Kitfox gear would be easier to make. I don't kmow what the ramifications would be of using that on the Avid. The attach points are in the same location on bothm and the fuselage dimensions are also pretty close.

    Most of my tubing was .049 wall thickness. The only thing I used a lathe for was making the spring stops.

    When I build again I will use heavier strapping at the top and bottom of the spring strut.

    Have a look at a Super Cub or a clone. I copied from that, a Hatz Biplane and the Highwing LLC gear.
