    If you print the drawings I posted in files and forms, then  go to UPS or a copy store, they can enlarge them until the yardstick is actual  size - Lots cheaper than buying a pattern rib from Kitfox.  Just make sure your spar holes are the right distance apart.

    Ed I use drywall mud for the final smoothing (the white color over the foam) and then just apply paste floor wax before the layup.  Also UVA mold release can be used or hair spray over the wax.  Meguirs makes a mold release wax called Mirror Glaze 88 that is available at most auto parts stores which is a paste wax.  The nice thing about the foam is that it is easy to carve.  I also use X-30 liquid foam to fill voids and the likes, a 1 qt kit is more than enough to do a cowl

    Paul,
         I layed up fiberglass on metal parts for years, and have done vacuum bagging, but never used a foam form - Is there something you need to do after getting the foam in the shape you want, before laying on the resin/cloth?  does it stick to the foam?
    Thanks for posting.

    Welcome to the Neanderthal / Dinosaur club too!  If my feeble mind could figure it out, (with some help here), you can too.
    I belong to the X-class 3 club too, along with some others on here.
    Good flying, and keep posting.

    Plane has N number; looking through four inches of paper work to sort out unfamiliar terminologies.
    Plane still on a trailer the way it arrived. Was told it flew six weeks ago. Hmmmm. Log book looks like it was active until 2013.
    Just sold a C-172 I had for 19 years. Cancer. Treatable; cureable; we'll see. Don't have the patience or time to fight FAA next medical.
    I have a year to go on a good class 3 but when/If I were to go again, I'd get slammed, so on to the drover's license and a lighter rig.
    Computers are so arcane to my neandrathal mind, pictures are a future dream, but I'll try. Rather weld mufflers on my Studebakers upside down.
    Stopped in Casper for fuel in 2000 on way back from OSH in the Cessna.
    Thanks for responding.

    Cowling building
    Cowlings can be hard to find for some projects but they are not hard to build with epoxy and glass.  I am in the process of building one for a friends Piet at this time and have also built one for my Q-2. I am attaching some photos of the Piet cowl mould that is in the process at this tme.  And no, I am not interested in builiding cowls for anyone but it really is a fun and easy process.

    Welcome Art look here for the build manual and etc.  Oops, keep forgetting linking won't work with IE on this site, anyway look in the Avid Flyer General Hanger on this site and you will find most of what you are looking for.  Is this a completed and flying aircraft, N-number, airworthiness certificate and etc. or is this a work in progress?  There is also some info in the Yahoo site files section that will be helpful but this site has a lot of knowledgeable folk here to help you thru the process.  How about posting some pictures so we can get an idea where you are in the process.

    Art,
        Welcome to the Soob minorities on here - the snow-machine drivers are very tolerant of us.  I think the build manual for your plane is on here somewhere - maybe others can direct you to it or help with what you need.

    I added a modified Riblett Kitfox 4 profile to the bottom of my undercambered witngs - Just a 1/4 (6mm) rib extension and new capstrips, leaving the old capstrips on except at the wingtip - the profile is posted on here, I think, in "files and forms" and a few photos somewhere.  I can post a photo if needed.  The only other thing I had to do was replace my rear jury strut attachments with longer ones.
    And, I cut some old rib material aft of the rear spar and shortened the ribs by about 1 inch and relocated the trailing edges.
    YOU DON'T WANT a flat bottom!  The Kitfox 4 bottom is not flat.
    EdMO
    Maybe modifying your ribs and building like Avid, you wont have to buy Kitfox flaperons.

    Howdy, I'm Art Johnson in Nevada and I just bought an Avid C
    model serial #378 and I need the original build plans, paperwork etc. that didn't come with the plane.
    If anybody can help with this, I'd appreciate. TIA
    I plan to be a fairly regular poster, but I need to become more familiar with this bird before I can talk much about it.
    It has a Subaru engine.

    Doug , would it be possible to add a flat bottom on the undercamber HH riblettes I have to build them like a speed wing riblette, It would add a little weight but dont think it would be to difficult but not sure if that would cause other issues, I know I would have to also deal the fuel tanks.

  15. EDMO added a post in a topic Different wings   

    If you can get the symmetrical flaperons, you may be better off - Riblett said that the flat-bottom flaperons were a drag just like the undercambered ribs.

    $.02 of advise is to use the Kitfox Flapperons as well as the wing.  They are part of the system that makes the wing work.

    Thanks Doug always appreciate the knowledge you have stored up. I will seriouly look at the kitfox rib now that you mention not having to worry about extending the wing and which ever way I go will be using the removable kitfox wing tips, Thanks again

    No problem Luke.  There seems to be more than one side to every product or discussion, we can learn from each other.  I'm waiting for my ignition system from Ram Performance so I can have dependable dual ignitions and am dealing with fuel issues in the wing tank installation.  I've got a leaking fitting  and need to seal around the filler necks so fuel can'tget into the wing and mess up the paint job.  The leaking fitting caused fuel to drip onto the full glass (lexan) door.  Guess what happened?  I'll be replacing the lexan with an acrylic product that resists fuel damage.  Touch up painting will follow on the messed up paint.  
    Oh well, live and learn, better on the ground than in the air.

    Wolverine,
         Here are 3 photos of the Wing Support Assembly.
    I bought 3  PVC Schedule 40 pipes 10 feet long,
                  6  Elbows
                  2  T's
                      Glue
    The uprights and the 30 inch solid bottom tubes were not glued to the elbows and T's of the 15 inch tubes, but that might be necessary.  The two uprights have not been cut to length yet.   Another possibility is to insert a smaller tube into shortened uprights and drill and bolt it, or put a band clamp on it, when telescoped to the right height.
    I should have rotated the center photo, but too late now.
    Hope this may help someone.

    I will try to post some photos of the supports in a couple of days - As far as progress on my Foxy Flapper - work is slowly getting done - I am mostly working alone with an injured shoulder - nearest help is 20 miles away - the only aircraft welder is 50 miles away - I have the main gear on and the parts to make the nose gear but a little more welding is needed - wings are 90% and other parts are sitting on the shelf or waiting to be made - I will post a photo of the gears as soon as I can install the nose gear.  Flaps and ailerons are next to be built from scratch and will post some photos when that is completed.  The support photos will be on this post - The plane photos will be in "Foxy Flapper Fotos" in the Kitfox IV section.

    Yes, you want the KF 4-7 Riblett airfoil. KF 1-3 airfoil is almost a dead nuts copy of Avid HH airfoil, great STOL performance but both hit an aerodynamic wall around 90-95 mph due to the significant under camber. Anything more you are burning thru exponentially more fuel for incrementally smaller speed gains. The Riblett airfoil will get you in the air almost as quick but efficiently cruise at 110-115 mph all day long. If you use that airfoil, you also probably won't need the wing extensions as the 144" spar tube length you have is almost as long as the KF wing. Obviously, many KF 4-1200 Speedsters flying with the Riblett airfoil on shorter spars just fine!

    FWIW, I am using KF 4-7 Hoerner tips on my A+ wings with Avid speed ribs @ 12" o.c., the tips will add an additional 6-8" of wing length without the need for a separate section of wing extension. The KF wingtip design also makes it easy to fabricate removable tips, something the oem Avid tips do not. This is a plus for internal wing inspection, storage considerations (buddy here would remove wingtips in order to fit shorter, folded plane in his barn for winter storage, or just plain fun (I also have KF droop and KF standard non-Hoerner tips to interchange when the mood strikes).

    Keep in mind, KF wing tips for models 4-7 cross closely to Avid speed/Aerobat rib profile, NOT Avid Heavy Hauler/STOL rib profile. If you use the Avid HH ribs and are looking for alternatives to the oem Avid fixed tips, you will need to modify the oem tips or source the KF 1-3 tips for under cambered ribs. As Ed mentioned, most of these KF 1-3 tips were the 'droop' style tips but I do believe Skystar also offered the smaller, standard non-Hoerner tips sometime during model 3 production as an option. Just make sure it is for the under cambered rib as the current wing tips are much harder to modify In my experience.

    I take off from a very short grass strip, I used them alot, mine are set 15 deg. either full or none for take off and landing...
     
    I start the take off roll with no flaps, lift the tail wheel as soon as possible, when I reach 35kt  pull full flap and back the stick a little. Rest is history!
     
    for landing, I come with full until I´m about to touch the ground, then I retract them fully to reduce ground effect and I will stop very fast.
     
    like Leny and Jeoy said, without flaps, is like having a muscle car on bicycle wheels!!

    Thanks guys for the info, maybe I will l price out some kitfox Ribs and flaperons ( Kitfox 4 is what i would be after I think) I will have to read  up on it again but if I remember I would gain alot of airspeed and still have the same   stall speed. I may take you up on that Ed but probably wont get nothing started till winter, to dam busy right now.

    HANDY WING SUPPORTS
    In case anyone wants some photos, I am in the process of building two wing supports out of 1 1/2 inch schedule 40 PVC pipes.   These can be your missing person if you ever need to support a wing.
    I need them to hold the wings while two of us tack-weld the new struts and fittings.  I will have a mostly bare fuselage with no engine or ballast to keep it from tipping over.
    Another thought, these fold and store and could be used for a temporary support under one wing while you fold the other under less than ideal conditions without a helper. 
    I am sure that they could be made in smaller pieces for more convenience - you can always improve on an original design.
    Post if you want photos, dimensions, etc.
