    I bought a 7 mm wide and 5 m long USB endoscope with LED lighting at the front of the camera via eBay from some company in HongKong and I got it two weeks later via ordinary mail to Sweden. I have  also ordered some crimp tools for coax wires and D-sub pins and it has worked great. I have always received the goods and been surprised of the prices. The payment were made via PayPal. 
     
    The endoscope was very easy to use, after the CD software was installed, all I had to do was to plug it to the computer and start using it. The software stared automatically on the computer when the USB was plugged in. The intention is to use it to inspect the inside of a broken longeron for corrosion. The plan is first to clean the longeron with the type of steel brush that is used for rifles with an extra extension, push the camera inside, take pictures every 4 inches and take notes on a paper in parallel. Then I can study the pictures thoroughly afterwards and depending on the results, possibly inspect some places closer a second time.

  2. allonsye added a post in a topic Dimensions of Kitfox 582 oversize belly radiator?   

    I'm preparing to install a belly radiator. I get the 2" from the belly bottom dimension but I was wondering respective of exhaust heat, what would be the minimum setback from the muffler with a 582 setup?  The easiest place is roughly 1/2 way between the firewall and the landing gear. I was wondering though if that's far enough from exhaust heat flow.

    I shipped a cowl by greyhound before, but honestly don't remember what I did! Must be getting old )  I would call Greyhound and ask what they need. If it has to be boxed or not. It is VERY reasonable to send by Greyhound!

    Chris,
         Maybe you can give me and Luke some info on how to ship a cowl by Greyhound or cheapest way?
    BTW:  Hoping to have some photos of my Grove tri-gear to post soon.
    Thanx,

    Dimi3 - yes, those wings were off my Aerotrek. I bought new wings from the factory to comply with their SLSA repair manual but thinking I may repair the old ones and sell or use them on my A+ someday.

    No problem Chris. I'm glad you found a solution. Can we expect some updates on your build thread 
     
    Ed, I'd be happy to give you the cowl if we could figure out an easy way to get it to you.

    Thanks for the info - I really don't see how the brace tube between the struts could make any difference -  The data would be nice to have before I weld my new struts - what would be the reason for thicker walls on the brace tube???
    I wonder what size  brace tubes are on the Magnum.  What size are Magnum struts?
    Some struts don't even have a brace tube.   Some wings only have 1 strut - some have none!  I don't remember what the Taylorcraft had - been a while since I got up close to one.

    Ed, the differences between the 1050 and 1200 are subtle, but there are three major ones:
     
    1 - Lift struts are 7/8" diameter on the 1050 and 1" on the 1200
    2 - The tube between the lift strut attachments was increased in wall thickness (I don't remember the details)
    3 - The rudder and vertical fin are 10" taller on the 1200 over the 1050.
     
    The funny thing on the lift strut differences is the rod end bearings (adjustment at the wing) are the same on both and these are the weak link in that chain.

    Well those are interesting pictures Doug, what´s that? eurofox? aerotrek? I thought, making the ribs on aluminium and riveting them to the spar was more easy than glue and plywood, but then again, the AVID/FK wings are one of the most easy to build wings ever.

    Luke and Ed-
     
    I was able to verify that a MKIV cheek radiator type cowl bottom will indeed work with the Fat Avid cowl top that I have. So Luke my direction has changed and I will not need your cowl set. Therefore you and Ed can work something out. Many thanks for the offer though Luke. It was greatly appreciated! 
     
    I think I have a lead on a MKIV cowl bottom too, so hopefully everything will work out.

    What makes the difference between the KF 1050 and the 1200 GW?  I seem to remember that one Kitfox was limited to 1050 because it had the 503 engine.
    Nice looking X-TriPacer

    I bought a bigger plane, the Kitfox is a bit short of space for camping gear. I bought this 1959 Piper PA-22/20 with a seaplane door, leading edge cuff and extended wings, it should be a decent bush plane. Won't be quite as economical to operate as the Kitfox, but if I take out the back seat it should be able to haul a lot of camping gear.

    I can't say with 100% certainty that it was made to fit a MKIV. That is my understanding though. The guy I bought the plane from got it from another guy that was going to build the plane with an O-200. The first guy had purchased this cowl to use for this purpose (MKIV with O-200). That's all I know

    Tonight I am supposed to get (borrow) a MKIV cowl bottom to see if it will mate up with the Fat Avid Cowl top I have. I will report back tomorrow with a picture or two. Luke this may have an impact on whether I will need your cowl set or not.
     
    And to make sure, Luke the cowl set in the pictures was made to fit a MKIV airframe?

    Looks like a very nice machine. Are you leaving the flying business or just upgrading?

    Doug,
         I understand what you have shown - I am not debating it.   However, like you were saying, changing ribs can be a real pain if your tanks don't fit - His Avid tanks may give him trouble with real Kitfox 4 ribs, or Kitfox tanks may not fit Avid ribs because of the spar hole location in the ribs.  He needs to use the rib hole location which makes his tanks fit.
         I am not afraid of the modified undercamber ribs - The NASA rib design turned out to be a dud, and they are supposed to be smarter than me!  Just look at how many "bad" designed ribs that have flown without failure.
         Harry Riblett even recommended doing that same modification to the undercambered ribs, and even suggested using his 35 inch rib pattern to replace the original Kitfox shorter ribs.  His letter and drawing and dimensions were posted on our "Files and Forms" section.
    EDMO
    Even the Clark Y rib, like on early Pipers, with a flat bottom, should be an improvement in cruise over the Eppler Avid and early Kitfox undercambered rib.  Barnaby Wainfain published an excellent little book on rib designs.

    Well Ed, I'm not an aeronautical engineer so I can't say what effect changing any one or multiple combination of characteristics to the HH airfoil will have. My comments are limited to trying to modify the Avid HH rib airfoil to mimic the KF 4-7 rib airfoil exactly. I'll leave the 'close enough', mix 'n match stuff and test flights to others.
     
    I think you might be surprised at how different the two airfoils actually are, it's not just "a tiny bit more curve on the top". The top airfoil, the lower airfoil, the rear spar hole location and leading edge are all notably different, as are the leading edge and capstrip width. I think modifying HH ribs into KF 4-7 rib clones would be a LOT of work. IMHO, it would be easier to just route out a new set.
     
    Some more pics that might be useful...
     
    These show a KF4-7 rib against an Avid 'transitional' rib (speed rib lower profile with HH upper profile). The special transitional rib is used to mate Rib #1 on an Avid Speed wing or Aerobat to the butt rib on the fuse). Avid rib has oval cutouts in the web, KF rib has truss like cutouts. Clearly, the top airfoil surface of the Avid HH/STOL rib is quite a bit different than the KF4-7 Riblett airfoil. Even though it doesn't show well in the pic, the Avid capstrip actually sits directly on the spar. Capstrip on the KF rib sits ~1/4" above the KF rib. While it might sound insignificant, it created huge issues when I used the old Skystar slip-in wing tanks in my Avid Mk-IV HH wing.
     

     

     

     
    These pics show the underside difference between the KF4-7 rib and my A+ butt rib (Avid's HH/STOL top and bottom airfoil profile).

    ^ That's what I understood too. And, unless something changed, I believe both Skystar and KF had extruded aluminum stiffeners for the .065" spars only, not .083" spars. According to Steve Winder, Avid and [old] Airdale were able to source extruded aluminum stiffener material that fit the .083" thick spar tube at one time, but it was so expensive given the small amounts ordered that they dropped it. I've never heard of or seen a definitive source since then.

    Being near Neanderthal, I had no idea that it took so long to download a video - now I appreciate them even more.
    Don't look for any of them from me - I probably couldn't turn the camera on!
