    Chris,
    Thanks!
    Did you go with different sized compression type springs on the chains to dampen the shimmy?
    I’m running a Maule pneumatic tailwheel and tire now and I don’t have a shimmy anymore, but I think I used different sized springs this time which probably helped...
    Thanks,
    Ron

    Ha!  That is actually how I found them Joey!  I wish we lived closer, we share the same hobbies!

    This is the “Finch” tip...Ed is right about dangerous!  I Think the idea is that they deflect the wingtip vortices further off the wing...or maybe they just wanted Magnum pilots to wear eye patches like Pirates?

    Thomas,
    Your Magnum looks great!  I like the changes you have made.
    Springs can be reheated and tempered if you find a shop willing to do it.
    I used this place http://www.alcanspring.com/
    I talked to Bill.  He is a good guy and made a spring for me for cheap!  Just make a detailed drawing and send it to him.
    I modified my tailpost mount and went with a Husky type spring with three leaves.  I did it so I might have a more universal spring and mount, so later I could maybe go with one of those fancy T3 shock systems.
    Let me know if you need anything else.

    It’ easy once you get tired of the manual and pitch it in the trash

    I think I know what you are saying...I’ll attach a pic...
    Not from my bird, but it is the second Magnum built by Avid.
    The ribs are sunken into the tank...the PO had done this step already when I bought it, so I’m not much help in the how to area...
    Another thing worthy of mention in the pic is that they did not wrap these tanks with fiberglass!  You will have to fit the ribs after wrapping fiberglass over the tank and spars.
    Maybe somebody, that has actually done this can jump in here?
    I did a whole lot of filling and sanding to get that area smooth so that part of a rib wouldn’t stick out.
    Thanks,
    Ron

    Barry, you are correct it is the rear part of the rib glued to the back of the fuel tank...
    Welcome to the Magnum Manual Land of confusion!

    Looks good Barry!  I like the left only trim tab! I might have to change mine....

    Joey, you spend more time in the sand than David Hasselhoff!  Stay safe and I hope the time passes quickly...
    I saw your pics on FB and that place looks the same and I haven’t been there in over ten years!
     
    Take care,
    Ron

    Joey,
    It is about $1500-$1800 depending on the gps antenna and premade wiring harness options.  That is kind of a standard cost across the board.
    There is another company making one that hooks up to the wingtip and uses the power and ground wires already there for the light...pretty cool too...

    I'm replying to my own post again which is the first sign of a posting problem
    I verbally trashed the Matco Tailwheel, but after finally getting time to look at the tail wheel, there is nothing wrong with it!  It is a simple design and a quite hearty design.
    I had a lot of trouble taxiing with it on pavement, just because it had enough surface area on the pavement to stretch my springs instead of turning the wheel.  Things got better with forward momentum, but still kind of stiff feeling.
    I also got some of our Pueblo mud stuck between the tire and the forks, which barely clear each other...after flying for about an hour the mud dried like concrete and when I set the tail down it started hopping!
    But as I said above, the real problem was that the shimmy I had experienced with it actually shook the metal lock nut loose and helped cause the slow motion runway excursion...
    If I were doing most of my operations off airport I would be putting it back on!
    I just wanted to clarify that the Tailwheel did not fail, it is a solid part...

    Simple ADS-B Out solution
    For those of us needing in and out of airspace after 2020 there are several experimental ads-b out solutions.  I went with the iLevil Beacon this month and just finished the install.  It is a self contained unit that looks like a com antenna that you mount on the belly.  It came with a 9 foot wiring harness, one end connecting to the Beacon with a cannon plug, and the other has a 9 pin plug and two wires for 12 volt power and a ground.  The 9 pin plug connects to an LCD that you panel mount (1 3/4" diameter hole) and you use the LCD to setup and monitor the Beacon.  The Beacon contains it's own GPS system but does require a gps antenna.  iLevil sells a Rami gps antenna, but it is pricey.
    The Beacon can "sniff" your squawk code out, without wiring to the transponder.  The sniffed squawk will be displayed on the LCD screen so you can verify it.
    It is 2020 compliant and if you haven't looked at iLevil technology, you are missing out!  Check out their "Bom" that will be released in December!  Super cool!
    Anyway, easy install...
    Ron

    Barry,
    look around on the forum, there are lots of discussions about it...pros = no ethanol deterioration of tanks, cons = some have had trouble with the seal releasing from the fiberglass and clogging filters, or leaving an un protected piece of fiberglass that the ethanol ate through and caused a leak.
    you bought the 160hp O-320, so 100LL is in your future anyway...
    If 100LL goes away, you and I both will be replacing our fiberglass tanks, so we can share the misery at least.

    Looking good Barry!  This looks a lot better than the green goop!
