    Thanks, staying away from Ebay
     
    I've been talking with the guy on Barnstromers.  It's a 17 yr old engine that's just come off a KF that was ground looped and had a prop strike.  No entries in the engine log since 2006.  He wont come off his asking price.  Maybe I'm wrong but just a few too many issues for that $.

    Looking at the video, I would guess that he has a Kitfox 4 or 5 - I didn't pay that much attention to which model.
    I just started this to try to find out if there were differences between Avid and Kitfox and what models.

    All of the fittings for finger screens that I have seen are 3/8 male NPT, with a 1/4 female NPT hole in them.
    However, I believe I have seen some Avid fittings which look smaller.
    The 3/8 NPT is much larger than any of the other 3/8 fittings - probably about 3/4 inch diameter.  It is now listed as 3/8 MIT, or Male International (Thread, or Taper?) but I think it is the same as the old NPT.
    Kitfox uses a Permatex 9AR sealant, and I think Leni posted the other sealant which works good, or maybe the other numbers for this same sealant. 
    Sometimes the threads in the tanks need to be refreshed with an NPT tap, but use caution not to get them too large.
    Hope this helps.

    I would guess that he possibly upgraded to the IV system or just didn't know he could fold without disconnecting them

    Beware of scams on ebay - dHolly and I got involved in one of these 912 "bargains" this year - looked like a way to hack your puter, or your money!

    Thanks for the info - it is my understanding that the cables are supported at the end of the housing, and would have to be disconnected before folding wings.
    No problem either way - I just didn't understand why my KF1&2 wings would fold without disconnecting, and the video Crazed Pilot put on u-tube shows him disconnecting controls to fold wings - looks like a later model Kitfox on there.

    Kitfox IV changed the design. The 1-3 was an exact copy of the Avid. IV through SS is the same.

    The Avid 5/+/Airdale were different using teleflex cables. I don't know if that needs to be disconnected.

    New Header tank for the Avid
    Hello Group,
     
    I bought a header tank with a little bit more capacity to increase my range, this one has about 15 liters (almost 4 gallons); and I will take the opportunity to replace all the fuel lines, as per inspector recommendation to teflon hose and/or aluminium pipe, I know it more expensive this way, however  I won´t have to deal with fuel lines anymore. Out of sight out of mind! (hopefully).
     
    I bought all the fittings on ebay, from racing cars fuel lines, AN-6 and so forth. HOWEVER I came across a problem I had and solved in a very CRUDE way, I Don´t know what type of thread the female WING tank fitting is, I bought it from Brett 3 years ago, and forgot to ask, I placed a NPT 3/8 fitting and it always leaked; but I covered it all up with fuel/oil resistance silicone and work ok.
     
    anybody know what type of thread this whole is?? is a 3/8 but BSP, UNF, ??
     
    Thanks in advance.

    Now if some smart designer would just look at the rear windows on the J3, and use that little channel or some similar on his doors, he could just slip the polycarb into the channel with a rubber seal and not have to worry about screw holes and cracking!

    Guess someone eliminated the swivel in the connecting rods?  On what models?
    I will have to disconnect mine because I have changed the design to separate flap and aileron control rods - and I'm not as smart as DW - by a long shot!

    Dean got it right and his design has been improved on.  It takes about 5 seconds to disconnect the controls.  Fewer parts that introduce slop into the aileron controls.

    Thanks Leni,
         I didn't know that.  I was certainly not trying to diminish what Dean had designed.  It is always easier to improve a design than to make the original.  I thought that maybe some of Denny's team had done that - Guess they must have missed the good DW design on some of the Kitfox models?  Why do the videos always show the controls being disconnected to fold the wings?  Check out the Green Kitfox U-tube video: "Folding Kitfox Wings, by Crazed Pilot".  Happy Birthday to him today!

    You didn't have to disconnect the controls on an avid A through mk IV ...

    I am a big fan of DW - But, did he get it right, or just close?
    I don't know about any of the Avid models, but there are Kitfox models that let you swing the wings without disconnecting the controls - Looks like someone improved on the DW design.  Anyone have info on which models of either brand folds easier, and how did they do that?

    Welcome to the dark side. If your here to hack on Larry step up to the plate and start swinging sweet plane! I love the lexan doors on mine, but flying in the cold temps -30 they don't seem to last long without cracking around the screw holes. I normally replace mine every year, but it's cheap and only takes a couple hours to replace.

    Welcome to AFF!! Keep plugging away at your bird and you'll be ready to rock by spring. You probably already know the other KF drivers in the Spokane area. I got my Private ticket at SFF in 2005 when I stationed at Fairchild and grew up not far from Lewiston. Really miss the area.

    FNG from Spokane
    Hey guys- been a lurker for a while, finally figured I had to sign up over here to give Larry a bad time:-) Used to be a longtime Mooney owner, sold my Mooney this year and bought a low hour Kitfox Model IV. Been pretty much spending the summer getting used to the plane, making all the necessary(to me) changes and trying to get the damn thing to run right. My life is pretty much airplanes, motorcycles, cars, snowmobiles, basically anything with a engine in it.
    Here is a summary of my plane-

    94 Model IV Longwing 1200
    80 HP Rotax 912UL
    Warp drive prop switching to IVO in flight adjustable
    Updated from bungee to Grove gear
    Currently working on my doors(switching to see thru)

    I bought the Acrylic bubble doors from LP Aero, cracked them right out of the gate, got pissed off and switched to polycarbonate. I am still working on them and progress has been really slow. Here is the latest in progress pic-

    It is possible, yes, but that would require redoing the complete firewall forward including the engine mount and cowling.  The Kitfox V and newer use an engine mount that pushes the engine about 6" forward and puts the oil tank on the right side, just below and behind the cylinders.  This was done because that airframe was designed to mount the boat anchor weight certified motors.  Moving weight forward was needed to keep in balance.
     
    The 1-4 Kitfoxes were designed for 75# two stroke motors under the cowl.  When the  912 came along and people were finally sick of fouled plugs, smoke, stink, high file burn and the general unreliability associated with two strokes ( ), Kitfox did what they had to do in order to make them work.  These early 912 mounts kept the motor as compact and rearward as possible.  This is the reason for the odd style oil tank mounting.  It is still far better than the oil tank in the trunk method that Avid used.
     
    I don't really like the setup, but it is far more trouble than worth to reengineer the whole thing.  I thought a long time about redoing this on my project plane.  I finally decided that it still wasn't worth the time and expense to rework the whole FWF.

    Some people may not be OK with a slight variation of the wing profile right at the tank, hence the "they won't work" statement... Some of us are not quite so picky and we know we are not building an oshkosh winner, just an honest flying machine... the tanks will work for us that fly our planes instead of polishing them
