  1. There was a transition period between C and MKIV that was initially called a 'D'.  I had serial number 941, and it had some, but not all of the MKIV changes, and all the build manuals called it a 'D'.

     


  2. I've moved my Avid on to another owner, but he wasn't interested in the floats.  Original Avid floats, not amphibs.  I have the floats and the water rudders.

    I'm in Florida.  I'll post pics when I get a chance.

  3. Those are old tires - Armstrong has been out of business for a long time.  Someone bought them, and I have the exact same tires with the new name, but can't remember it.  Anyway, when I got mine, I foolishly put the max psi - bad idea, it makes an already difficult ground handling airplane really squirrely!  I think I found in the Avid build manual that 8lbs is the desired air pressure.

  4. Jim beat me to it, but I'd also want a good look at the inside of that tube - it looks like there is a lot of rust around that crack.

  5. My model C build manual is actually called a model D build manual, which I guess was the original name for what became the Mark IV.  Mine has most of the MK IV mods, like the cheek radiators and the round tail.


  6. That tube would carry the impact loads from taildragger main gear (the forward main gear mounting points, nose wheel main gear go on the mounting points behind) to the rest of the fuselage structure I think.  Basic structure looks similar to my model C, but I don't have any good pictures of mine to compare it with.

     


  7. Its not unreasonable, but the non-profit part would be since someone would be getting paid to produce parts. The price of the parts would have to be in the form of a "donation".

    Common misunderstanding of Non-Profit.  Non-Profit doesn't mean the organization can't charge (Hospitals being a prime example), and it also doesn't mean it can't make a profit - no organization can survive if it doesn't make a profit.  What it means is those profits are entirely invested back into the organization, and none are distributed to the benefit of individuals (shareholders/investors/etc.).

    This probably wouldn't meet the bar for a 501(c3) however.  The 'benefit to the community' part would be a tough sell.  Focus on the educational aspects, and it might fly. (Pun intended)

  8. For those that live where water can be solid, make sure you apply it to the top of the elevator only - on the bottom can trap water and freeze the elevator in place.

  9. And for the really cheapo pilots like me, a nice golf cart tire at $60 a piece!  The tire is pretty slick, and behaves well on pavement. And I swear my golf handicap is going down, too.

    Those are exactly the tires that my Model C came with - then manufacturer name was different, but when I replaced them the only change in all the sidewall was the manufacturer name to Carlisle.  I don't recall who manufactured them originally.


  10. I have a ratchet rake, it works well.  My only problem with it is my tractor isn't big enough.  The ratchet rake grabs the stuff very well, but then my tractor either spins the wheels or just grunts and sits there :o.  And that's in Florida sandy soil!  It's not sage, but mostly palmetto and small water oaks (evil evil trees!) . My tractor is only 23hp, so if you have a big enough tractor it should rip that stuff right up.

  11. The thing that kills fiberglass is UV exposure (and alcohol as Jim mentioned).  As long as they are covered so no UV gets to them, they'll last a very long time.

  12. That is why when someone says they are going to slosh their tanks I say 'NO, Don't do it!'

  13. I always like it when people tell me I'm right... Granted, it doesn't happen all that often, but it's nice when it does.  :lmao:JImChuk

    And I suspect that it is never your wife telling you that you are right!  :biker2:
