    Thanks for noting the need for a brace on the stinger Larry, we added it because of that.
    Yes, nice hangar isn't it! My buddy is letting me use it for the swap since it is heated and mine isn't.  Nothing like having good friends!

    Mark,
    Congrats on the new plane.  You need to post up some pictures.
    That s a pretty unique engine for these planes but know that KF built the factory demonstrator plane with a 2800 Rotec.  They could probably give you an idea what worked best for them if they did any testing of props on the plane.  Also Rotec should give you a good idea what props would work best for your preferred mission with your plane.
    I have run Warp Drive, IVO and Whirlwind on my Subaru; all 3 blade and from 70" to 72" and they all work fine with about 100 hp.  There are so many variables, but I tend to like the longer props.  I've always wondered if the larger frontal area of the radial engine would require a longer prop to get good airflow than the same hp engine with a smaller frontal area?
    I look forward to hearing how you like it.  Welcome to the Forum.

    MATCO Tail wheel shimmy
    Dear friends,
    I am no more Avid/Fox breed owner as you already know, but my Bristell is tail dragger as well. Tail wheel used is MATCO light weight version of the dual fork eight inch tail wheel WHLT- 8LD installed as full swiveling version, mounted on dual steel spring. (see picture below)
    During one year of operations (mostly on paved RWY) I am facing troubles with strong shimmy vibrations in the case of three-pointer landing (not often, rather on mains) or in the case I am putting tail to ground soon after landing.
    I would like to know what could be o reason for such vibrations.
    Thank you for any opinion

    It's the factory Rotax muffler kit but it might be a newer model than the one you have.  The muffler has ball and socket connections for the pipes to the muffler.  The kit has all the socket ends, the pipe ends that fit into the head, 4 180 degree elbow fittings, all the pipes and all the springs and spring tabs.  It just takes a talented bender and welder to complete.

    I must admit that I did not see the location of the decimal point on the caliper as a depth gauge.  Screen too small, I guess.  Gotta agree with JimChuk here in that too good is vastly preferable to too bad.  This certainly makes the splice approach look good.  My bad.  Nobody is going to do a stress analysis of the spar in its current condition, so we could go around and around and ultimately never reach any meaningful conclusion.

    Hi,  I am in the process of building a Kitfox 3.  Acquired a nice kit here in Alaska,  fuselage is nicely powder coated.  Just finishing building the wings right now.  Great forum, invaluable advice!  Probably be bugging for advice too as the build progresses.  Thanks and Hi.

    I think Fred said something like abra-cadabra and snapped his fingers 3 times.  Maybe that will work for you.  JImChuk
    PS  seriously though, it will be interesting to see how that prop performs on the Jabiru engine

    My deal with Roman direct went well too.  Long wait but good deal.
    Those props are a work of art.
    And I shoulda hired Fred to come over to do my engine swap with the same method used in the video above.

    Im excited too and yes I bought directly from them Nice people to work with did everything I wanted got blue tips painted on and leading edge laid in the carbon fiber the prop is extremely nice looking. I got a 2 blade. took about 2 mounts to get but that is not a problem. I didn't care much for the western union money transfer. That cost me 35 dollars. But it did go smoothly. And I would buy another from them.

    I actually run mine at .021-.022" gap for the same reason.

    Hard starting...and the cure!
    So my 912 has been taking longer to start as it has been getting colder and running very rough and shaking hard while it gets going. I assumed it was just the thicker oil causing it to crank slower. I am thinking this rough starting contributed to my exhaust cracking.
    Anyway the last time I changed the plugs was a while ago, before I flew the plane to Oshkosh on Avgas the whole way. So, I bought a set of plugs and put them in this weekend thinking changing them out might help.
    When I removed the plugs they were actually a lot cleaner than I expected. I had removed one or two after oshkosh just to have a look. There was some crud around the electrode and insulators but not so bad that I thought they needed replacement. I decided to keep running them since it was starting and running great, but it was still summer. 
    When I took them out this weekend they looked a lot cleaner than when I got back from Osh, but the gap had REALLY widened out! That was surprising because the nothing looked eroded, but the spark gaps were definitely in the 030+ range!
    I put the new plugs in with a "tight" 025 gap and all I can say is WOW! New plugs not only made the plane start WAY faster, they smoothed up what has been a SLOW deterioration in engine smoothness. The deterioriation in starting and smoothness was so slow that it had gone unnoticed until it finally became a problem.
    So if the colder weather seems to have affected the way your plane is starting and running, Change the plugs! You will be SO happy you did!

    I bid on one of the carts of spruce, thinking I'd keep whoever got it honest, but no one took the challenge.  They extended some items, so I got a few others as well to make the trip worth it.  I got a lot more spruce than it looked like in the picture, the 8ft bed of my truck is full!
    One of the things I got was a Matco MHMH6B wheel assembly, including the caliper and axle.  So if anyone needs one, I have one I can let go cheap!  If not, I'll have a project to use it on eventually, I'm sure.

  15. Chris Bolkan added a post in a topic Another Forced Landing - Mine   

    So sorry to hear about the bird and great that you were not hurt. Have you had the time to look back and assess your decision to perform the impossible turn as opposed to having landed in the cut corn? I am curious as to whether you think the outcome would have been any different.
    In a similar situation of having to make an important decision VERY quickly, I decided to apply power and attempt a go around instead of just riding out a bad landing in my Magnum. I made the wrong decision in hindsight and applied power to go around. All it ended up doing was adding a lot more energy to the bad landing and resulted in more damage than would have happened had I just rode it out. We walked away too, but the plane is requiring a lot more work to fix.

    Back around 1997/8 Ivo convinced the owner of Europa Aircraft to try one of the in-flight adjustable props on the mono-wheel 914 powered demonstrator. We put it on just before Sun & Fun, flew it about an hour and were doing ground runups with it when Ivan Shaw (Europa's owner) noticed the tips flexing thru a two or three inch arc on full power runups.  He said to remove it, box it back up and send it back. While I thought it was smooth in flight I never liked the foam core (yes the originals were foam C.D.) and really didn't like that much flex in a prop. I know a lot of people swear by them but I am not one of them.

    Tjay, I would love to hear what you think about this propeller. Did you get a two or three blade.  I email them about getting one sent to the USA. Did you order from them direct or through a distributor?

    Glad you're o.k..  So sad to hear about your bird.  When I bought mine, the previous owner had put a paper fuel filter behind the seat, between the wing tank and header tank.  When I took it off I discovered a small amount of water trapped there by its higher surface tension relative to fuel.  Had that filled with water the fuel flow would have stopped, as Leni will attest.  The proper place for any fuel filter is downstream of the header tank, as it really is a huge gascolator!  I hope this wasn't your problem.

    Very nice looking setup, Randy.  (...and Leni!)
    Is that a Rotax muffler-can or custom as well?

    You can install a Subaru but it is very heavy. A friend had on on his MK4. He had to add weight back in front of his tail wheel to keep her from being very nose heavy.
    It performed well and the engine was much cheaper than the usual engines used.
