    Wow, glad you got it home, but what a pain in the neck to have to go through.  JImChuk

  2. 1avidflyer added a post in a topic Tall and Wide Cabane Gear w/ no seat truss loading   

    I'm trying to figure out exactly what you are trying to do.  As it is, the standard cabane style gear doesn't load the seat truss, rather it pulls in from the sides and can buckle the bottom tube of the seat truss in compression.   (unless that is what you are referring to)  I actually think it's good to tie the seat truss to the center of the cabane.  A load on the seat truss pushes out on the bottom of the seat truss, just the opposite of what the cabane does. I think tying them together will help to cancel out those stresses.  I've actually done that on my Avid MK IV.    JImChuk

    There are two types of EGT thermocouples.  With the one style you just drill a 3/16" hole in the manifold and the thermocouple  is held in place with a hose clamp that the thermocouple has been fit into.  The other style screws into a fitting that is welded to the manifold.  As I remember, the distance from the piston skirt should be 100 MM to the thermocouple.

    I have an unused Avid heat box and a fiberglass radiator scoop.  JImChuk

    With the double radiators, one will have hotter coolant than the other.  Therefore you would want to use the first one in the run.  As I remember, that is the one on the right (passenger)side.  Memory isn't always the best though.... JImChuk

    Each one had good and bad points.  The heat muff I had on the 582 worked good for it.  With the 912 in the Kitfox, I have a thermostat (thermo-bob) and you run a bypass line off of it and go through the heater core with that bypass line.  When the thermostat opens, the coolant wants to flow through that larger hose, and you loose some heat.  When I do the next one, I will run the 1" line through the heater core (I have one with 1" fittings) and the thermostat will be down stream of the heater core.  That should do real well for heat then.  Trouble with the heater core, is everything gets so cramped for space.  Like 10 lbs of crap in a 5 lb bag.....  JImChuk

    There was an Avid Bandit that was something of a lighter weight MK IV.  Maybe that is what you have and someone nicknamed it a lite.  Kitfox made a Kitfox lite that was a single seater, also they made a light weight version of the Kitfox 4 call a Lite Squared   (2 seat)  JImChuk

    What engine are you looking to use a Magnum on?  That is a big prop.  If you are running a 912 rotax, you probably want the IVO medium or ultralight.  I do have an IVO medium 70" three blade IFA that I will sell.  You can private message me if you like.  Thanks,  JImChuk

    I'm in northern Mn, so we see plenty of cold weather as well.  In fact, it's +16 F and we have 6" of snow on the ground right now.  The thing with coolant for heat, is when you want it the most, the engine will be cooled as well and have a harder time giving some to you.  The muffler will get hot anytime you are running at cruise rpm.   I do have a heater core running on my Kitfox 4, and it does ok.  JImChuk

    I built a muffler shroud for my 582 muffler and it worked pretty good.  I ended up fitting a fiberglass "funnel" behind the radiator like Chris talked about in his last post to push air though the muffler shroud.  That did produce pretty good heat.  Had to put the muffler mounts on the ends of the muffler and hang it off the firewall, but that is a better way to hang the muffler anyway.  The tubing Avid used that hangs from the engine is subject to cracking.  Heater thoughts? - Technical tasks - AvidFoxFlyers Forums  have a look at this thread to see what I did.  This was before I connected inlet air to the back of the radiator.  That improved the heat considerably.  JImChuk

    Interesting, mine is 1176D.  On the FAA page, it's listed as being manufactured in 1992.  I believe that date is when it was registered with the FAA, not when the kit was built by Avid.  JImChuk

    Maybe....  If you can show a picture of your door latch, the tubing just behind the seat where there should be a shock absorber for holding the door open, also a picture of the rear spar carry through.  Here are some of my Avid MK IV.  JImChuk

  16. 1avidflyer added a post in a topic Diffference between Mk IV and Avid Lite?   

    To the best of my knowledge, there never was an Avid lite.  Also, Avids serial numbers were in order, for instance, 805, 806, 807 which would have been C models.  When the MK IV came along, they added a D to the end, so a MK IV may have a serial # like 1234D.  I think the MK IV made it up to 1600 or 1700 serial number before they stopped being made.   But in the USA, when one registers a homebuilt plane, you can call it what you want, and make up a serial number.  Some traits of a MK IV is the door latch changed to being about 1/3 back on the bottom of the door, earlier ones were in lower front corner.  Baggage compartment, front of vertical stabilizer centered on the top of the fuselage, extra tubing just above and behind the seat to hold a shock absorber to hold doors open, additional gussets at rear carry through.  Your plane is extremely light for a MK IV.....  JImChuk

    The motor mount bolts will keep the firewall in place.  I tie the bottom of mine to the floorboards, but I make the firewall about 1 1/2" to tall, and bend the bottom 1 1/2" back so it parallels the floorboards.

  19. 1avidflyer added a post in a topic Which is the Widest cockpit and useful load   

    First Avid and Kitfox were 36" wide.  Kitfox 2, 3, and 4 and Avid B, C, and MK IV are all 39 1/2" wide.  Useful load is hard to figure, cause depending on how it's built, and Kitfox 4 might weigh anywhere from maybe 550 and 800 pluss lbs.  My Kitfox 4 was 826 when I got it, and after complete rebuild, it weighed 645.  I have no first hand experience with newer model Kitfoxes, so will leave that to someone else.  JImChuk

    Not quite understanding your last post, here is the firewall I made for my Avid MK IV with Jabiru when I rebuilt the plane.  Notice how the stainless steel firewall recesses into the tubing at the bottom center.  JImChuk

    My Kitfox 4 is 43 1/2" wide.  That is 4" over stock.  I think the Merle Williams widening kit adds 5" on a Kitfox 4.  My useful load is about 550.  JImChuk

    Maybe to give more clearence for the carb?  Pretty tight on the Jabiru, and I think there are similarities between the two engines.  JImChuk

    Very nice Bucky!  I'm glad you got it back to where it should be.  In the air!  You can be proud of the accomplishment.  And if you had a larger smile on your face, I think it would be allowed.     JImChuk

    I've got no first hand experience with the tires you have, but know that on our Aeronca Chief, with 600/6 tires, it would get more bouncy with more than about 12-14 lbs of air pressure.  I'm sure the Chief was heavier than your Avid.   I would expect you would have the same results with maximum pressure.  JImChuk

  25. 1avidflyer added a post in a topic Interesting comparison of descent rates in Avid verses Kitfox   

    I have a 69 1/2" two blade NR on the Kitfox, and a 64" two blade warp drive on the Avid.  Engine idle rpm is close to the same in both at that point, but of course the Kitfox had the  gearbox, and the Jabiru in the Avid is direct drive.  Maybe if it was winter and I had a large lake under me and I was on skis, I would shut off the engine and see what the difference was.  With trees everywhere around me I'm not sure I'm up to shutting down on purpose.  The one engine out landing I had in the Avid, it seemed to glide just fine at 60, but I can't say what the rate of descent was.  JImChuk
