    ya, I know it is probably a long shot but I was trying to cheat a little.

    Flaperon hanger needed
    Looking for a couple flaperon hangers for my kitfox II. I could actually return them after I’m done using them as I plan to temporarily bolt them to the rib tails then slide a tube through to the turtle deck in order to mark the cutouts dead nuts. I can purchase or rent either one, let me know what you have.

    For whatever reason the above photos didn’t go up in any particular order, oh well, I’m sure everyone can figure out what’s going on.
    I guess the time flies, this is where I was at this time last year.

    Been working on the firewall forward and it’s basically done now. With everything completed I will need to get the engine back on my test stand and verify the exhaust, intake and fuel system I came up with perform correctly.

    3/4 .049 tube is what I used for the cabane truss. I didn’t “engineer” my landing gear but I did find a link on this site  to an old article that gave some guidance on designing a cabane style gear, it explained how moving  mounting points and angles varied the loads through the fuselage, I used what I learned in that article to design my gear. I haven’t seen any pictures of how the kitfox fuselage fails on a hard landing when equipped with a cabane gear but I suspect the lower longerons at the front mounting point will be pushed in towards each other.

    This is the best I can do on the photos.

    Between 6”-7”. I built a truss that was basically the width of the fuse and about 6” tall and welded it to the bottom of the seat truss structure.

    A skidoo 503190854 seems to work well.

    Thanks for the compliments!  Build threads and flying videos keep me motivated, that’s one of the reasons I’ve been documenting my build here.

    Find some material the same thickness as the tubing you intend to weld and set up various types of weld joints with it and start welding them up, once you have that mastered you will be ready to start practicing on the tubing.
    Something like this makes excellent practice.

    Pretty much everything TJay said. I think pure argon is going to make matters worse, C25 works well.  Use the .025 wire, your machine should have a chart with setting guidelines, I have found them to be pretty much spot on.

    Those are the best photos I’ve got of how I did my adapter, obviously there is more than one way to skin a cat, it’s great to see others figuring this out and going for it.  The bottom picture is the clutch drum after my initial engine testing, no wear or clutch dust.
