KA10...???

Anybody knows a Russian stunter called KA10?

In Christ,

No,
but can you describe him?

The KA10 is a .60 sized stunt ship designed by Anatoly Kolesnikov. Tom Dixon recreated the design after communicating with some European competitors. Tom did a Model Aviation article on the plane a couple of years ago. I believe this design has been used, with modifications, by a number of European (especially Eastern European) competitors. Yuri Yatsenko's plane is very similar, except Yuri stated that his canopy is considerably higher and his fuselage is wider.

I have a KA10 under construction for some time (I'm slow). It is a Dixon kit. Tom does his 'kept foam' technique, which is heavier than built-up, but lighter than most foam wings. The wing really builds easily. Mine was going to be powered with a MVVS 49. However, last Summer I acquired a Discovery Retro 60 at the WC, so I'm going to fit that as well.

The attached picture is from Tom Dixon's MA article.

Ditto everything Fred wrote. There were two rudder shape options. TD started with a small 3 view, and either it showed two shapes or he didn't like the original and gave an option. There is also a KA-11 version, which has the revision of a Patternmaster airfoil (a good choice). Scott Urabe showed up with a KA-10 several times at the NW CL Regionals. Scott's paintwork is unique and spectacular, with raindrops painted on, actually done with drops of water, somehow. This one sez it has a Saito .56, but a ST .60, 2Star .60bb or Lite, or an SSW Magnum/ASP .53 would be a nice match. I think the wing area is about 650 sq. inches, particularly nice for a smaller flier. This is Scott Urabe's KA-10. Steve

One of the new young experts in our club (North Coast Controlliners), Mike Alimov, is from Tashkent in Uzbekistan (sp?).He has met Anatoly and probably knows as much about this aircraft as anyone in the states.He,ll probably post here shortly.---Mike? ----------Gary T.

Gary,
while I have not personally met Mr. Kolesnikov, I had a privilege to watch him fly at the 1988 WCH in Kiev, Ukraine. That year, he was flying the KA-10, a picture of which can be found on PAMPA website.
I also happen to have a construction article of his airplane, published in 1980 (?). One day I might find time to translate and publish it... While it looked somewhat different from KA-10, many design trends have carried through. One thing I remember is a very high aspect ratio - over 6, which I believe was reduced in the KA-10 to more like 5 - 5.5.
Now, someone mentioned tall Russian canopies as a characteristic trend. That's true; you'll be hard pressed to find a Russian / Ukrainian design that doesn't have one. I spent a lot of time thinking about the purpose of those. It clearly wasn't for aestetics alone! In those planes, form followed function, period. Considering how many disadvantages a tall canopy brings (extra drag, weight, side area, etc), there must have been a pressing need to keep putting those on.
After re-reading the KA's article for the 500th time, I realized how much emphasis he put on symmetry. He located engine, wing, and stab on the same axis. The purpose was to make airpane turn inside and outside the same way. Having built planes of this configuration as well as the traditional (with offset), I can attest that it works.
Which lead me to think that the reason behind the tall canopies was the need to compensate for the pitching forces the fixed landing gear puts on the airplane!

I've noticed that a lot of the Russian designs feature a (sometimes ridiculously) high canopy. Is there a method to the madness? Are they are trying to balance the frontal area around the thrust centerline or something?

Russia has excess capacity to produce canopy-grade plexiglass.

Another guess is perhaps the model designers wanted to keep the proportions close to actual planes. Take a look at the russian aerobatic planes like SU-26 or Yak-50,-52 or-55 series. They all had prominent canopies.

Steven, these look super planes. Know where one can get 3-views?
Couple of questions :-
1)The one you've headed SU25 has SU26 along the bottom of the photo?
2)The one you've headed Yak 29 has SU29 painted on the fus?
Can you confirm designations?
Regards,

>Steven, these look super planes. Know where one can get

Try www.aviation.ru They have a very extensive library of russian designs with links to other sites.

>1)The one you've headed SU25 has SU26 along the bottom of
>the photo?
Eh, my mistake. It is su26. Su-25 is russian equivalent of A-10. Not quiet as successfull but still deadly.

>2)The one you've headed Yak 29 has SU29 painted on the fus?
You are correct on that one too. It is SU29. Yak29 does not exist.

I've always liked the looks of the Yak-50 for some reason. There are a couple of Yak-52s at our local airport and I always think I need to find the owner and buy, beg or grovel for a ride...

Has anyone seen or know of a PA version of the Yak-50? Are there any plans available?

>Yak 50

Steven,

Yes the A/C identification on the last two planes are incorrect. The Red single seat is a Suhkoi 26m. The second plane (yak 29) is actually a Suhkoi 29. I know this plane very well as I have many hours flying the plane in the picture. That plane is N292SU ans was owned by Mile Merritt. The plane was destroyed at an air show in the late 90s while performing by Miles. There are many Suk's in the USA although most are the 26 model. They are all great planes and can take a lot more than the pilot can give it as far as "G" loading! I see where there was a post with a good looking model version of a friend of mine "Tiger Tom Klauson" on here the otherday. I think it should make a nice plane and look good in the air. Anyway, Have a great day.

"Ars Longa , Vita Brevis"
In Christ,

I traded some stuff to Walter Hicks for a KA-10 a while ago. One more coat of clear and I should be ready to mount an ST 60 , L.G. and wheels and go flying. I still have to make a cowl, but I'll start flying without it. I think the high canopy has something to do with frontal area in front of the cg. Something like a pylon style free flight I'm told. I think Bob Hunt has published articles on this subject.
Happy Landings

I had the KA 10 that John Wright now has. It weighed 55 ounces and was
powered by a Double Star .61 Lite SE. It was Dixon kit and had Monokote and Lustercoat for the finishing system. Very easy to build
as I had two disasters with other planes that same year and needed
something in a hurry. It has Carbon Fiber landing gear also. It flew
well as it is not a really large plane 640 sq in wing. Lots of power
is always good. It does have an inline wing stab design too.The article in Model Avaition is helpful. Also I used Tom Dixons paint
scheme and got a lot of complements.

How can I get this article?

In Christ,

Try emailing Rich LaGrange. He's the librarian at the American Modeler's Association (AMA).

Best wishes. -- Iain

Our own CaptCurt is the keeper of the PAMPA Library, and should be able to send you a copy of the article, maybe electronically, for a fair price. Steve

Ian,

I mean no offense, but doesn't AMA in this context mean Academy of Model Aeronautics?

I KNOW it's not the American Medical Association!

Model Aviation Article - if you cannot get it let me know and I will mail a copy to you. I believe Ihave one somewhere.

Walter,
An update on "our" KA-10. It's in the air again, ST-60, ST muffler, 0.281 venturi, 12-6 Tornado nylon, 8 oz clunk tank, haven't weighed it yet but should be same as when you had it. The first 3 flights revealed a small warp in the wing. That will be fixed soon. I will go up in venturi size for more power, and a Modusa 12-6 3B. It handles nice so far. Just a few simple manuvers, no patterns yet.
