Does anyone have a good set of the Shoestring construction drawings they are willing to sell? Thanks Marc

Fellow homebuilders, My search to find a copy of the Landis Ketner drawn Shoestring racer drawings is turning out to be both difficult and frustrating. I started by posting an ad on Barnstormers then posting here on EAA365. I have spent many hours on the computer and telephone researching and running down leads. This is the story so far. I found Landis Ketner's phone number just by chance and am glad to report that the man who drafted the Shoestring construction drawings is still alive and appears to be active in EAA chapter 99 in Vero Beach. I have spoken to him by telephone twice over the past week and altho a seemingly nice fellow, he is not at all interested in helping me find a set of drawings.Landis told me that he sold all of the material he had on the Shoestring to a fellow he would not name many years ago. It was Landis understanding that this un named fellow had plans to manufacture kits and parts to sell to homebuilders but liability raised it's ugly head and thus his desires were put on dry ice. What a crying shame. Later I stumbled across a fellow named Gerald Morrissey who has been building a Shoestring from Ketner drawings and he has taken up my cause and is trying to help me any way he can. Thanks a lot Gerald. Still though, it's No Dice on finding me a set of drawings. I found a web site that is advertising plans and parts for a Shoestring inspired racer called SnoShoo that loosly translates No Shoestring. The fuselage appears to be close to a Shoestring but wings and tail are all new. Since I want to build a box stock replica of the origional no. 16 red and yellow Shoestring, their fuselage drawings, if stock, is all I would be interested in. I did however try to contact their principal, Mr. Alan VanMetar via telephone and E-mail but so far no response. A few days ago I got a call from a very affible airline pilot in North Dallas who offered to sell me his no.24 Shoestring that was involved in a runway over run accident in 1999. The wing is not airworthy and there is no firewall forward but the fuselage has been repaired and re painted. Alas that would prove to be too expensive and time consuming to figure out how to build my own Shoestring however I found out that we are both Acro Cubby owners so when he gets back from an over sea trip I'll fly my cub over and visit with him. Now don't any of you crafty homebuilder foxes out there try to buy that Shoestring out from under me because if I can't find construction drawings to purchase, that may be my only option.Well, there you have it so far. Please, if any one of you fellows out there know where I can purchase those drawings, let me know. Thanks Marc (817) 948-1263 firstname.lastname@example.org

This unnamed fellow...if I recall several years ago the Kitplanes Plans Built Directory had the Shoestring listed. Have you checked that out? Perhaps the contact info may be valid still for the plans owner or at least a lead to track him down.? Just a thought.

Easy answer: Contact Bill Goebel at email@example.com. He has Shoestring drawings on CD. I've got a set from him and they are exactly what you need.
There has been a lot of discussion about the Shoestring racer, including a detailed report by a guy who finished and flwe one within the past couple of years. He found a few incorrect details, sucha as an incorrect angle of incidence on the tailplane, which are useful. http://www.warbirdinformationexchange.org/phpBB3/viewtopic.php?t=17299&start=345
Search around the site, you will find lots of information.

Yes I have the plans available on CD. $35 + $5 shpg. Bill
I also received the folllowing from a builder in Canada a few years ago re: the Kettner planset
I had a look at my Shoestring's horizontal stab today with the following observations:
The leading edge is shimmed up (more than the drawings) a total of .75 (3/4) inches by an additional block /shims under the fwd mount (the fwd top block under the vert stab LE steel bracket was reduced approximately the same amount) .
The aft lower mount blocks of the horizontal stab are reduced by approximately .25 (1/4) inch.
Ralph Moore of Titusville Fla. warned me of the horiz. stab issue but I figured at the time it was just his airplane's setup, so I test flew mine as per the drawings. Nothing like trying to land with a tailwheel airplane that wants to VIOLENTLY pitch nose up! (Bouncing off the runway numerous times at close to 100mph is NO fun!!). I had to hold fwd pressure on the stick to flare!
The end result of the correct stab angle will look odd as it will have a slight positive angle of incedence in comparison of the top of the turtle deck. The reason for the stab's angle is the air flowing over the top of the wing continues downward as it leaves the wing's trailing edge, hence the stab must fly in this same downward flowing air.
I later confirmed with photos Ray Cote's Shoestring#16 (in the San Diego Museum) stab angle is set similar to mine.
This is a saftey concern. I was lucky not to be injured.
Hope this info helps you.
