  1. I'm almost sure that T88 was the original glue used to make the ribs.  Your description fits it too.  The gray stuff (9460) will work too if you don't want to buy a tube of T88 just to make one rib.  EDMO

  2. It's too dark to be out joyriding in his new bird, so where is the Airworthiness Inspection report that Joey was supposed to have today?  Darn it Joey, you are keeping us in suspense - give us some kind of report!  Hope it is good.  I hope you are not on your way to play in the sandbox or to some nice island?  EDMO


  3. Maintenance: 43.1 B applicability - part 43 (which requires A&P, allows minor maintenance, etc.) does not apply.

    Condition inspection: What it says in the operating limitations. Probably should have written the repairman cert number.

    Folding wings without log book entry  - don't have a source for that, but obviously common with many models of aircraft. Is it covered in the aircraft "manual"?

     

    To me, Folding wings is like Opening doors - anything built to hinge is designed to be moveable and does not require any other action. ???  EDMO


  4. Never had a nose wheel Avid, but will add this.  When you push down on say the right pedal, the left one comes back/up.  When you  push on the left pedal, the right one comes back/up.  Remember that the rudder pedals are connected to the rudder by the cables on both sides.  That being the case, only one steering rod should really be needed I'm guessing.  JImChuk

    That's true Jim - I was thinking about the guy with the shimmy problem - seemed like more connections and redundancy would be better IMO.  I think Chris B put dual rods on his new nosewheel.  EDMO


  5. They must be rejects from ATF enforcement or something.  Completely WRONG!  The quality of federal employees is at an all time low.  Maybe I should apply!  :flamegun:

    Maybe we need to write a pilot's pre-flight checklist for those idiots - Maybe say, "Unfold and pin wings before takeoff"!  ;<)  EDMO


  6. I don't like "Ramp Checkers" most of them don't know what they are doing and are bored and curious.  They ramp-checked my Ercoupe once because they didn't have a clue about it and were just nosey - At least those were polite and only asked questions like they had never seen an Ercoupe before.  The ones who checked my Cessna and Cherokee had at least read the books.  Guess there aren't many books on Avids and Kitfoxes unless you are a builder, but there are FARs they could at least read!  EDMO


  7. Steve,  I am not an Avid owner, but I have been told that:  1.  The springs should return the nosewheel to straight when rolling.  2.  From what I have been told, the tie rod should go to the pedal that you push to make the plane turn opposite of the way the prop wants to turn the plane on takeoff, depending on whether you have a right-turning or left-turning prop.  I think tie rods to both center pedals would be better, but guess that was not the way it was designed.

  8. You were correct.  As the owner of an Experimental, you can do all maintenance, and as an A&P you can do condition inspections.  The builder was legal in doing a condition inspection too if he had a repairman's certificate or A&P number - He also had to do one before Airworthiness Inspection and that one does not require any certificate.  Unfolding wings does not require an inspection, as it is part of preflight duties of the pilot.  Those guys need to get educated enough to quit the BS!  Maybe read the FAR's for a change?  They probably knew that it was BS or they would have written you up on the spot!

     Nice looking bird.  EDMO (A&P/AMT)

  9. ☝️x2

    I've owned and flown both, adding the KF4-7 airfoil now would be the single best value add mod you could do IMHO. That, even assuming you paid full retail price for the new ribs and flaperons from KF Aircraft. There is a strong market for the model 1-3 ribs and flaperons as they are no longer produced. Doesn't add any additional build time really and the net OOP cost would be well worth it.

    Welcome, looking forward to following your build progress. Sure hope you get more done than the first three owners!

    That was my original thought too. The question is if I use the KF4 wing what are the limitations to it going past 100mph? What exactly is the limiting issue(s) with the KF3 VNE, windscreen, spars, wing construction, spar carry-through, tail, wing struts? 

    James

    I think the limiting cruise factor on the early wings is the drag factor of the bubble that forms in the undercamber - The KF4 and later Riblett airfoil eliminates that factor.  Windscreens are the same, unless you want to buy the aftermarket (from LPS?), all the rest are only involved in weight of plane.  The Kitfox 4-1050 has a VNE of 125 and I believe it had same lift struts and tail as the KF3 - These were made heavier on the Kitfox 4-1200 and the tail made taller.  At least you should be burning less fuel at cruise speeds equal to what the undercambered wings fly at because of less drag.

       I modified my undercambered ribs to be more like the Riblett by adding an extension under them with another ribcap on it, but I kept the rib tail hangers and made separate flaps and ailerons instead of the flaperons of the early models - I haven't completed the plane, but hoping someone will someday.   EDMO


  10. I think you should measure.  Level it up and snap lines on the floor and so the complete deal soup to nuts.  It's kinda fun actually. 

    Totally agree, and see how your measurements compare to the manual - Good way to have fun with on non-flying day.

    Guess today is your big inspection day - Hoping to get a good report soon!    EdMO


  11. The best thing about this site, except for the excellent members, is that you have the freedom to express any thoughts and not be banned for deviations from "standard" building of your bird.  You might get some better ideas, or negative input, or warnings that what you are doing may not be safe, but we believe "to each his own", and no one has to "conform".  Leni just lets us post up, and I think he enjoys a good battle!  Ha!  A lot of have flown "real" planes, but now enjoy our "toys" even more.   Post up about your toys - We love photos.  EDMO

  12. They are going with the most conservative number. I'm going to have to measure though. The pilot arm is at 16". It doesn't seem like it's another 4 ft to the back of the baggage area but perhaps it is.

    Joey,  The pilot arm should not be at the back of your butt or seat back - it is about the center of mass of your body. probably about where your belt buckle is located, or center of thigh - Of course that is for an FAA standard 170 lb pilot - others will vary, but the measurement is standard - measure that too from leading edge of wings before going on back to baggage and you may find the baggage rear is farther than you thought.  Kitfox 4 gives 18.3" for pilot, and 40.5" for baggage sack.  EDMO


  13. Even though the wings have stalled on landing there should be enough elevator power to keep the nose wheel off the ground at lower speeds - with power on, the nose should be able to raise long before stall speed is reached on takeoff.  EDMO


  14. Where is the one that says, "This is an Experimental plane built by Amateurs - Do you really want to fly in it?"   Ha!

    Wishing you a very good inspection report.    EDMO


  15. As Pocahantis once said, "Welcome Columbus"!   Any questions you have will probably get several (maybe different) answers.  EDMO


  16. What are the weight and balance numbers? A forward CG will not allow the pilot to "carry" the nose wheel AND will force faster landings. A terrible combination. The nose wheel should never see 40 MPH. 

    Not saying there isn't something wrong or broken with the nose wheel setup, but the 40 MPH number has me spooked.

    On my plane for example, the weight and balance is far enough back that I can lift the nose wheel within a few feet of beginning the takeoff roll, and can land and carry the nose wheel from touchdown thru taxiing and not set it down until it is time to stop. If the pilot cannot do that (pretty easily), his weight and balance is too far forward.

    Dean originally designed the Avid with a nose wheel and placed the main gear very close to the balance point so the nose wheel really has nothing to do with takeoff or landing other than a third point to balance on when the plane is stopped.

    One way to tell if his plane is in the ball park  is if he pushes the tail down to the ground is should stay there or be very close to staying down. Of course the best way to tell is by weighing and balancing :-)

    Chris

    Totally agree Chris - I could do almost the same thing with my Cessna 150 - With full up elevator and power, the plane would almost be on the tail with  or without brakes set - soft field takeoffs were on the mains only.  The Ercoupe was the opposite - it was nose heavy, and the nosewheel had to be kept on the ground for steering until ready to rotate.   Both had shimmy dampeners.   EDMO


  17. Is he sure that it is not his tire out of balance?  Out of round?   Some have put stronger springs on the Avid nosegear.  Does he only have a steering rod on the right pedal or both sides - That can make a huge difference.  Any slack in linkage can let it shimmy.  Is there a way to put a shimmy damper on it?  The 20 lb force on tire to turn wheel can easily be overcome by your legs - they will hardly notice it.  EdMO

  18. Doug,  I only have a very few days before next Chemo when I am not weak, tired and feel bad bone pains.  Last Chemo is Jan. 31, Feb. 1 & 2, then about 2 weeks to recover from that.  Should start radiation sometime after Chemo.  Lots of time to keep up with the news on FOX.  I agree.  EDMO


  19. Pumps can be piped up either way, depending on the pump.  Some have check valve(s) and some don't (both forward and back check valves).  Facet site has a chart with lots of valves, model numbers, pressures they produce, how high they will lift fuel, whether they have forward check valves, backward check valves, both, or no check valves, and type of fittings.  The round ones (Gold series?) have removable screens in them.  I like them better.   All of them push fuel up to some height - they don't pull.   I might have one, or two, to sell if you need one, either one square or two round, depending on what you need.  I don't know prices.  EDMO


  20. James,  After you type what you want for a post, scroll down and you will see "choose files" you can click on that and then open any photo on your computer and it will load them to the post in a few seconds - you can do this as many times as you want to - then submit post with photos.    I don't know anything about photos on a phone.  EDMO


  21. Jim Chuk posted some info on replacing bungees some time back - I think he said to order them in 19 or 23 foot lengths, (BUT don't go by what I say), and you would have a foot or so left to pull on and cut off when finished.   Maybe this was enough for 2?   I don't know where the post is.  EDMO


  22. Maybe something like this?

    Not exact what I had in mind - You still have a potential crack point at two places now - IMO, the sides should extend from one end of the bracket to the other - past the bolts.  But you couldn't do that on the uppen end because of the bend without welding.  EDMO
