  1. I have had several landing gear failures since going to the spring "bush gear". I have been researching the subject and have noted quite a few similar failures of that type gear, all in about the same location and of the same nature, Inward bending of the forward strut leg. I have been reluctant to re enforce that leg for fear of promoting a more serious failure elsewhere. The gear is a Chinese copy of the gear used by Piper from the 1930s onward but the Piper gear does not seem to suffer the same failure. Today I made a cardboard model of the gear geometry and I believe I have located the problem. The bottom anchor bolt for the spring leg on the "bush gear" is fastened to a metal plate welded between the front leg and the axle. When the spring strut is fully extended and bottoms out, or the spring becomes coil bound, that point then becomes a rigid fulcrum with the axle as a lever. The upward motion or the axle is then translated into an inward rotary motion on the front gear leg. The failure always seems to occur at the point halfway between the axle and the fuselage, which makes sense. I have never bent a rear strut, nor the spring strut, always the front one.

    Looking at photographs and real life examples of Piper, Hatz, and Pietenpol gear shows that the anchor point on those gear is at the inboard end of the axle. My model shows a significant difference in the movement of the middle of the forward gear leg when the anchor point is moved to the end of the axle. As a matter of fact, the farther inboard the pivot is, the lesser the rotary movement at the front gear leg center.

    I have yet to figure a force analysis on the gear, but I think i am onto something. I'll post more as I find more.
    On a positive note, my welding is getting better.

  2. So I've watched the old Avid promotional video on YouTube quite a bit.  It clearly states that you can put a 250 lb. person in the back, but then it says ingress is through the turtle deck.  Seriously?!?!  The other problem is, everywhere else I look, they say 150 lb. is the max in the baggage compartment.  I have two small kids that only weigh about 120 lbs. total.  I already tried to buy one magnum off barnstormers but some guy from Canada beat me to it.  I found another that I can try to buy but I'd like to hear from anyone who has flown them or been around them.  Is it significantly narrower in the baggage compartment?  Will it really hold 250 lbs?  What is ingress/egress like getting to the baggage compartment.  Don't get me wrong.  Sometimes my kids seem like baggage, but I'd still like to get them out after an unscheduled stop.
  3. I'm looking for a nice prop for my Avid Flyer C with a 582. "The backwards prop." I'm in California and glad to pay shipping, etc. You guys know what I need! Open to related comments and suggestions.

  4. I picked this baby up, locally, near Sacramento. Maybe someone here might even recognize it? Rotax 582. We're at KGOO.

  5. Post on Cg formula in Avid Model C

    By Laurean, posted
    Hello, 
    Can anyone provide me the formula for calculating the Cg on the Avid taildragger?
    Thanks.
  6. Anyone what model the speedwing and aerobat wing were introduced.  The history that I found here doesn't mention them until model C.  I have a possible B model that appears to have an aerobat wing, it is 23'8" long and undercambered, but it has 18" ribs on it.
    TIA
  7. Looking for Kitfox or Avid on floats, prefer amphibs. must have airworthy certificate. For tax reasons I need this completed by end of February 2017,  Can also buy plane and floats separately. Please call if you are considering selling.

  8. Hello all,
    I'm new to the site, great utility, thanks to all!
    I'm looking at an Avid Magnum for float flying is anyone flying one that could shed some light on how well they work, and what kind of floats would work best? I live on the Little Tennessee river so the shorter the take off the better.
     
    Thank you,
    All the best, David
  9. I'm using a hand-held radio at the moment, but really would like a panel-mounted "real" radio. Panel is rather full, but may could possibly move things around.  Was wondering what some of you are using and how it's mounted.  Any ideas or pics?  The MGL or Microair series look promising, but am unfamiliar with them.  Have King avionics in the Tomahawk, but don't need the certified price in my experimental (thank goodness).
  10. Buying a Avid Bandit with a 100-HP Subaru engine.  Just getting conditional at the moment, so nothing much to write about except superlative workmanship from the builder.  Has very few hours, so wondering if anyone could chime in on performance and/or handling in a similar bird.  Have flown Tomahawk for the past 9 years and will have a bit of a learning curve.
  11. Avid MK IV HH kit with the 16" stretch. I bought this about a year ago. I have purchased a bush landing gear from Brett along with a tail wheel. The short story is I am still building my house and need the money to keep going. Be happy to send photos on request. The kit is located in Goldendale WA. Asking $9,500 or best offer.
  12. To all the Kitfox owners out there, wonder if you could help me or do you know?
     
    I have an Avid Speedwing Mk 4, the 13 gallon right wing tank (as from the cockpit) has rotted due to ethanol. I see that Kitfox sell ethanol resistant tanks, will a Kitfox tank fit an Avid and if so which model Kitfox?

  13. Have posted this on the Avid Forum As well
    Anyone out there help me out? I have an Avid Speedwing Mk4 UK based. The fuel tank has rotted due to ethanol. I have removed the tank.
    Few questions,
    Does anyone have a spare tank I could buy for shipment to UK, its 13 gallon right wing (looking out when in cockpit). I could pay by Paypal if needed
    Will a Kitfox tank fit an Avid Wing, if so which Kitfox model tank? I see Kitfox have ethanol resistant tanks
    Has anyone made an aluminium tank?
     
    Many thanks Simon   G-BUIR

  15. I already have a Mark IV and just wanted to know the differane's.
  16. MUST SELL!!!!   Been trying on and off for a year and a half, crunch time!   I am moving, it's summer, my bird is still broken.  Someone HAS to want a set of 12'6" Full Lotus type floats for their LSA!   Difference between these and true FL are the aluminum skid plates and step stiffener. (step compression was a major complaint of FL and the low psi bladders)  Was rigged to be mounted on a KF2.  Never mounted on the airframe.  Been mounted in my rafters in a heated pole barn for 2 years.  Had someone back out on me, crates are already built if you want to ship them.  
     
    Brand new FL 12 footers are 14K.  These have never been used, but have been rigged for install.  Can still read "Alcoa" on the aluminum plates.  Uses FL bladders (made FL a little pissy, thus these aren't made anymore.  LOL)  Plus, besides the addition of the aluminum step stiffener/skid plate, they ARE exact copies of FL.  
     
    Asking 3500.  I think that's pretty fair, if you don't, MAKE OFFER...  Make offer on dog too, can be included.  LOL

  17. Hi Everyone,
     
    Well, I just put a down payment on a MK IV, and will be completing my training in it -- at least that is my hope. I got a couple insurance quotes from companies that WILL cover me as 1.5 hr pilot, however there are come caveats: I need 20 hours dual instead of the FAA minumum 15 for the SP ticket (fine, I may need that much anyway), but my instructor needs 250 TT in taildraggers, and 25 hrs TT in exact make and model in order to be covered.
     
    Now I heard this can be negotiated to a degree, but if they won't budge on these times, I can't just find a 3000 hr tailwheel instructor out here and go flying. I'll need to find a CFI with 250 tt in taildraggers and 25 hrs of time logged in an Avid/Kitfox. (I'm sure Kitfox time could be negotiated to count since they're so similar to Avids)
     
    Anyone know of a CFI in Southern California that meets these requirements? Anyone have any ideas? Thanks!
  18. Hi Guys,
     
    I'm new to this forum.  I'm an engineer and new-to-powered pilot (primarily a glider pilot).  I like the kitfox/avid design.  I'm not opposed to building one, if the price is right, but getting in the air now  appeals to me as well.  I'm in SoCal, and it seems most kitfox drivers and sales are back east.  What do you guys think of this one on barnstormers. ?
     
    Thanks,

  22. I posted this on the Avid Yahoo forum, but wanted to put it out to our Kitfox brethren too since we all basically represent the same family of aircraft.
     
    For anyone near southern California looking for an excuse to fly your Avid or Kitfox,
    here's info for the upcoming Flabob Low and Slow Fly In, with food, planes and
    fun events. There is a (meager) website for registration and meal signups here:

    http://www.lowandslowflyin.com


    Let's see how many Avids and Kitfoxes we can get out there on short notice. Maybe we can put
    on a good turnout for the type. You can't get much lower or slower than the Avid or Kitfox!
     
    Be sure to go to the link and register so that they know how many meals to plan for.
