    Those mounts are subject to cracking.  You are better off hanging the muffler off the firewall.  I welded plates on the ends of my muffler, fastened pieces of aluminum angel to the firewall and used some rubber belting between them.  It worked fine, and allowed me to make a wider muffler shroud for cabin heat.   JImChuk

    I actually have a two blade IVO currently for sale.  It's an ultralight model, two blade 72".  Bit to long for a 447, but they can be cut down real easy.  IVOs are very simple to adjust as well.   I would probably shorten it to 64" and see how it did.  I had a two blade 60" IVO on my Himax which had a 447 in it, and it was two small at that length.  JImChuk

    If it runs good, the prop or prop shaft are good places to look.  If that is a new prop because of a prop strike, maybe bent prop shaft in the gearbox??  Maybe put a dial indicator on it when the prop is off.  Two blade prop will run rougher that a three blade as well.  I have a 1" shaft I run through the prop that I rest on two real small drill bits to check for balance.  I've been tempted to buy a J3 kitten at times.  I was at the Hipps "factory" once, when we were visiting Greenville SC.  It's was about 20 miles from there in Saluda NC  JImChuk

    Well the conditional inspection is done, and we hauled my buddy's Kitfox to the airport this weekend.  Tight fit with the Chief in there, but it worked.  JImChuk

    Joey Myers recently put a 912 in his standard length Avid MK IV.  He had to put 10 lbs of weight in the tail buy he seems real happy with how it flys.  JImChuk

    Interesting comparison of descent rates in Avid verses Kitfox
    Hi all,  I was looking at some of my videos of flying the Avid MK IV and my Kitfox 4, and I knew that I showed a much bigger descent rate in the Kitfox 4 (long wing) than in the Avid MK IV.  Kitfox weight is about 650, Avid is about 610 empty.  Stall speeds are about the same in both planes.   Kind of figured maybe the verticle speed indicators were not very accurate as I was seeing nearly double amount of descent in the Kitfox.  That was on base leg, at about 60 mph in each plane.  Well when I looked at videos, and timed the descents, I showed 200' descent in 30 seconds in the Avid  (400' per minute) , and 400' descent in the Kitfox in 37 seconds  (almost 650' per minute.  I would have expected the Kitfox would have had a better glide than the Avid, but it seems not.  JImChuk

  9. 1avidflyer added a post in a topic Stretching an airplane question?   

    I think the biggest reason for stretching the Avid was when they hang a heavy engine on the nose, like a Subaru.  Avids tend to be a bit on the nose heavy side even with a 582.  Probably help the ground handling as well cause the Avid is pretty short coupled.  The early Kitfoxes, ( 3 and 4 at least) are about 9" longer than the Avid so maybe they need it less.   JImChuk

    Wow TJay,  Pretty nice.  Now I see why you were wanting a bit faster cruise speed. Video to follow?  JImChuk

    You can contact the FAA and see what they say.  Most likely, if you are the heir, they will want you to complete an heir at law form.  I'll put a link to one below.  I'll try to find the phone number for you to call the FAA.  Do it when you have some time to kill, cause you may wait an hr or more on hold.  Try this one...   (866) 762-9434    JImChuk

    Not bad price,  If you could get the registration reinstated, it would be better.  That is not real hard to do if one is the legal owner such as an heir.   JImChuk

    .040" thick x 3/4" wide should be fine I would think.

    Tailwheel spring has a 3/16" bolt on each side going through that tab with the holes in it.  A piece of strap is under the spring and the bolts go through it.    The windshield is sort of cut to fit.  If I could find the windshield I had in the Kitfox 1, I could trace out a pattern.  Been a few yrs though and it's probably gone now.  Might want to consider a better supported engine I would say.  There is a Kitfox 1 build manual in the files and forms section of this forum.  Feel free to ask questions.  JImChuk

    Bummer.  He seemed like a good guy in the experiences I had with him.  This getting old and what comes with it stinks.  Condolences to his friends and family.  JImChuk

  20. 1avidflyer added a post in a topic Added 1 degree pitch to my prop   

    Interesting to see the performance changes.  Glad you like the changes.  Have you seen my laser prop adjuster?  I figure in 20' one degree will move the laser 4" on the wall.  I usually get within 1/8".  Funny how you can actually see the laser move as you tighten.  If you tighten one bolt first, it twists the blade one way, tighten other bolt first and it twists the other way.

    Quite the project.  Welds and fitting leave a lot to be desired for sure.  I don't think this fuselage came out of the Avid factory jig.

  22. 1avidflyer added a post in a topic Parts manufacturing for Avid + Mark IV   

    I just looked at your pictures again.  I see it's 1.02 meters wide, not 1.2, so it's about 40" wide.  I'm not sure what you are asking for with the distance between the leading edge pin and the spar pin.  The distance from the front wing attachment point to the rear attachment point is 27 1/2" center to center.  Looks like yours was close to that.  JImChuk

    The stock Avid B, C, and MK IV were 39 1/2" wide at the elbows.  The 1.2 meters seems pretty wide.  About 47"   JImChuk

    Spars are 27 1/2" center to center, so should be 25" between them.  JImChuk

    Lots of things in it that don't look like an Avid.  Wonder if someone copied an Avid?  JImChuk
