    Looking closer I do see the springs, still very different from what they were marketing under Highwing LLC.

    Interesting to note that he is not using their Hatz style bush gear but running shocks.  I went to the Roberts Rage gear struts which uses a combination of shocks,  bungees and gear legs of my own design and have been very pleased.  No more bent up fuselage.

    For me there are only two choices for fuselage,  Epoxy or powder coating.  Either way it maybe something to farm out.  Some of the prices for powder coating that folks have been getting would be hard to beat.  The downside to pc is that it is hard to get it off if you need to do repairs and rust can grow out of sight under the coat.  Painting there is a lot of waste, time consuming and a fair amount of specialized equipment to do a good job safely. Think outside air source for breathing.
    Sandblasting takes a lot of air so the bigger the betters far as compressors go.  I've used some of the small pot blasters and was less than impressed, ok for small projects only.
    So all that said I would probably tackle the job myself using Epoxy but I do own all of the painting equipment.  Sandblasting I would farm out because it is a nasty job requiring big compressor, a big sand pot and lots of heavy media.
    The above is just my thought and worth about what you paid for it.

    It is the stock oil tank if you have the stock mount.

    You are probably aware that you can buy it from  KF.

    The MK IV build manual is available for download on this site.  I fly a MK IV with a 912ULS and as you stated the performance is great.  I built a SS exhaust for my plane using bends but I used the original muffler.  The back two cylinder pipe are very tight and I would wait until you have the engine mounted to see what you need. I looked at an exhaust for KF four but was not able to verify that it would fit and the folks at KF were interested in giving me measurements to see if it was possible.  I now have a friend with a KF and could check it out to see if it would work.  There are a few places around that can build you an exhaust but you have to do all of the figuring so you might as well just do the fitting and get someone who tig welds SS to put it together for you. attached is a picture of the old pipes.

    Hey Allen, it appears your 2 has an additional piece of metal (black) above the spring.  Is that something that you added or did someone else add that.  That appears to be a good viable solution to the weak point without the need for welding.  It gives added reinforcement to the tabs and also helps hold the spring in alignment with the downward facing ears.  Thanks for posting the picture.  I believe I will make a part like that for my friends plane and see how it works out.
    You seem to be missing the spacers to the bottom plate the allows proper tightening without bending the bottom plate. You ca see them in Jim's picture above and on the KF site under manual, landing gear.

    Weak point in the Kitfox tailwheel spring attachment design
    i have seen several failures of the tabs that hold the tail spring in alignment at the vertical fin post when stressed.  The Avid MK IV DESIGN is much more robust and I suggest that if your fuselage is not covered that you consider making that modification and for that matter even if it is covered.  They never seem to fail at a convenient time.  If anyone is interested I can provide pictures of the Avid and also how we modified Larry's old plane (Old Yellow) after the tab failed at Johnson Creek last year.  If you land perfectly every time then maybe you don't need to think about this little upgrade.  This happened again today to another KF at a flyin that I attended.  I wonder if KF has made improvements in their later models, 5 and beyond?
    i just looked at a drawing on the Kitfox site and they are still using the same design on the S7, to bad.

  12. wypaul added a post in a topic nose wheel fork   

    Like most kits, no technical drawings were released for the Avid.  The fork was built at the factory and supplied with the kit.  As far as rigging goes that was supplied with the build manual but there are drawing showing a better modified rigging for th nose wheel steering that should be available on this site. It is possible that someone here will be able to provide the dimensions from their fork so that you could build one if that is your intent.  They do come up for sale here occasionally so ask if that is what you want.

    Looks like I will be going to Oshkosh arriving Monday but don't know if I will be flying the Avid or riding in my friend's Kitfox. Sounds like the weather is going to cooperate to make it very pleasant. 
    Sounds like I will have a couple more Back Country Super Cubs to test fly when I get back.  That is always interesting but as I have mentioned before I really like flying the Avid more.

    You may recall the article bout the double end stol in Sport Aviation maybe around 2014. The basic design of the Honda is pretty much a copy of this.
