  1. There are some fire proof coating that you spray on that work amazingly well these days that Bruce at Backcountry was telling me about.  I should find out what it is.

  2. Mine has worked just fine for 1200+ hours and I fly in some pretty strong crosswinds here in WY  I've taxied in winds blowing 34, gusting to 38 with a direct crosswind.  It does take some braking on the leeward, downwind side. Not fun but sometimes the wind really comes up while out flying.  Note the TW pictured above is free castering, not steerable.  I'm running the 8" Marco with the wide tire. It does have a weakness in design, I think if I had it to do over I would go for the 8" with the standard pneumatic tire.


  3. My thought is by moving the front mount forward you move to a position of less strength.  From my experience on my Avid there was a failure at the rear mount that caused/added to, the failure at the front mount.  My solution was to move the rear mount to the rear attach point of the tricycle gear at the wing strut attach point when I built my current gear.  Also installed the Roberts Rage Gear gear strut with the new gear and several other design changes.  This has proven itself by surviving an estimated 30 MPH forced ground loop to keep from going off a 15-20 embankment.  The plane did a 180 degree turn pivoting around the right gear when I stomped on the right brake. The only damage was to my nervous system, the plane was undamaged.

    the pictures are of the gear after installation.  There was no engineering in the design just seat of the pants design from the school of hard knocks.

  4. My MK IV kit came with VDO analog gauges.  Sounds like it time to get some new gauges.


  5. Situations like these keep me from wanting a 912. I think I'll save my pennies for a bird with a Cont or Lyco on the nose. They may be old, outdated, heavy and came here on the Mayflower, but they are pretty simple and reliable. I know from all reports that the 912 is a great engine, or at least till something starts going south.

    I just flew a Scout that a friend bought, up from Colorado today.  Great airplane, O-360 constant speed prop. It flew a little slower than my Avid and burned 10.1 g/hr .Costs around 2.5 times what my MK IV would sell for ($80,000+ USD) and I can tell you that I would not trade my plane for it for it even if he kicked in $10,000.  The Avid is a lot more fun to fly.  The Scout is definitely a great plane and will fit his mission well. I can fly it anytime I want but doubt that I will just because, for me the Avid is just a GREAT little plane and did I mention FUN TO FLY.  

    All engines suck when you are having problems with them and life is good when they are running good.  Finish that plane up Allen and come on out and have some fun!

    i feel for you Jim and have been thinking about your issues, hope you find it soon.


  6. Well I'm at a loss, so I figured why not take a shot at it.  Ordered a couple of #30 idle jets.  Thanks for the tip.  If it works.....  :unsure:JImChuk

    hmmm, didn't do better with carbs from the other engine so is it fair to assume that it is not likely the carbs? I take it that you have checked for leaks in the manifold and crossover.  Have you Checked the temperatures of all of the exhaust stacks to see if one is lower than the rest? Man I feel for you been there done that and did not get a shirt to boot


  7. They are available thru Walmart.com aircraft store.  Seem like I remember paying about $10 each, for them.  I bought two.  Same tire but the two I got from Matco didn't last but the Walmart one is doing great. Go figure.

  8. The were several groups of bad floats for the 912/914.  Same sorts of symptoms, I fought mine for months finally found the info.  The pisser for me was I had rebuilt the carbs including new floats so I didn't suspect them to be bad but they were.  There is a SB out on the whole thing.  If you can't find it let know and I will look it up.  It gives you a couple of ways to check them, including weighing them which is the best way.

  9. Jim it is a ETX680C, they cost a lot more but worth it I believe.  I put mine in the original position under the baggage compartment Avid MK IV.  ONE nice thing about the Lithium iron phosphate is how they work in the cold weather, hit the starter for a couple of seconds then wait five and the battery comes up to full power.  Also they hold their charge for months with very little loss. A downside is they take a special charger.


  10. The only paint that will stand up to PolyTone that I know of, is Epoxy and not all of them.  If you want to be sure use the PolyFiber brand.  Unfortunately only available in two colors, White and green.
