New kit offering *UPDATED*

Hi All,

Let me introduce to you the newest addition to our fine line of kits.

This sharp looking model is called the "SAKITUMI". The SAKITUMI is a flapless profile stunter designed to perform as well as a full bodied Flapped Pro Stunter but without the challenges that flaps bring.

Easy to set up for an LA46 using a 12.25 APC Prop and either a clunk or profile tank, an electric version is also in the works.

The SAKITUMI is responsive and performs like a fully flapped plane with tight corners and smooth rounds. Excellent line tension everywhere. Very easy to fly with great wind penetration and excellent tracking - upright or inverted. It literally cuts through any kind of air because of its airfoil.

Easy to build light and rigid due to the Geodetic wing and very simple fuselage. The wing requires no jigs as it locks together and sits on tabs built into the ribs and spar. All you need is a flat surface to build on and once the wing is near complete, simply snap the tabs off. A construction article is to be featured this year in an upcoming issue of Stunt news. (Plans not available in S.N.)


.35-.46 eng.
55.50" WING SPAN
621 SQ.IN. WING AREA
Prototype weighs 38oz

The SAKITUMI is designed by: Eliott Scott, The 1st Prototype was built by Eliott Scott and Mike Scholtes with general interference / motivation by Kim Mortimer.

OOOOOOOOOOOOH, me want! Walter, you are crankin' 'em out faster than I can earn the cash! End of September is tight. I'm running out of places to hide the boxes. I need to ponder... .

This design looks strangely familiar.

Hi Phil

In answer to your suggestion, the SAKITUMI was inspired by three un-flapped designs; the Primary Force, the Doctor, and the TEOSAWKI. I always thought that the TEOSAWKI was a great design. It is particularly sad that no kit or ARF is available any longer. I used a TEOSAWKI and Primary Force for nearly 3 years and they helped me learn the pattern as well as win a number of contests. I retired my TEOSAWKI this year in memory of its designer, the late Clayton Smith who I have huge respect for and who kindly prepared an ARC version for me. Clayton designed and popularized a very clever plane, it would be great if permission would be granted to someone of the families choosing who could issue plans or a kit.

The SAKITUMI was designed to take the best of the unflapped planes I had flown and make a really great practice and intermediate plane.

RE Design; I didn't work completely alone on the design and drafting. John Miller was outstanding in his help with the early CAD drawings and his suggestion of a very effective airfoil was important, the design has a thick very forward high point airfoil, it is similar to the shape of full size Aerobatic planes, and somewhat different from the TEOSAWKI which is a lot slimer with a different high point. John has gone into some detail about this and Airfoils on the other forum.

Other elements that would differentiate the SAKITUMI from the TEOSAWKI are
The fuslage design
The fuse construction
The CG location
The fin shape
The Nose moment
The wing root
The wing tip
The wing shape and sweep
The wingspan
The wing area
The wing construction
The leadout guide
The tip weight box
The spar design
The stab thickness
The stab area
The stab construction
The elevator area
The elevator construction
The landing gear
The wheel pants
Etc etc

Overall I am very happy with the SAKITUMI, I hope a few other folks get to enjoy one.

Eliott

Unusual airfoil.

Is this where things are going?

Charles

Wasn't it the late Clayton Smith who designed and built the
Teosawki?

Best regards,

Richard Ferrell

Yes It was Clayton Smith, you are right.

Had a "Senior moment" with his second name, I only ever knew him as Clayton.

Thanks for the correction.

Walter, what percentage is the airfoil? Look's somewhat "thin"...
Thanks,

The high point measures just a few thousands under 2" at the root. At the tip, its a few thousands over 1 1/4".

The root of the wing is rather wide, so the actual percentage, at the root, is 12%.

Since the root is slightly over 14", a 20% thick wing would be 2.8" thick. Way too thick for the horsepower Elliot designed this plane for, IMHO.
