Is there a Sisu kit?

I visited the Smithsonian Air and Space Museum for the first time last week. At the Hazy center, the lovely lines of a Sisu sailplane really caught my eye. Is there a kit of this available anywhere? Or plans perhaps - surely someone has modeled this plane before.

Where's the lift?

Hi, Richard!

As far as I know, you are on your own with this one. I've never seen or heard of a kit-version Sisu 1A (or even a scratch-build version, for that matter). I agree-- it's a beautiful sailplane, and deserves to be modelled. Why not be the first guy to show up with one?

We'll be watching for your build thread...

Here's a photo from Elmira with the tail unfolded.

I guess unfloding the tail would be a crucial part of the pre-flight! Neat ship.

Pre-Flight of the SISU

I agree the SISU1A would make a great project to undertake and fly.

Frank Lilly used to own this very Sisu 1a ,serial #1.
I used to crew for Frank years ago and put this sailplane together many times.
I've always wanted to scratch build at least a 1/3rd scale size of this sailplane
and maybe someday it will happen.
We have a great group of aerotow fliers here and that makes the reasons even easier to try.

Frank sold this sailplane some 20 years ago and it look's GREAT with the new finnish done in the original colors.

Thanks for letting me reminisce.

Thanks for the encouragement, I've got Bob Banka's documentation on order - didn't find much other information available via google.

It has been my intention to do the Sisu 1A in quarter or larger scale at some point in the future as part of our series of great American sailplane models. imsloper, if you provide us with accurate dimensions and station point cross sections, I would be glad to produce the glass fuse and foam cores for your project.

Thanks for the generous offer, I'll take you up on that when this project gets past the fantasy/beer talk stage.

Sisu 1A History

Doing a little reminiscing of my own this morning Tim and found this link I had never clicked on before:

A compelling story of the development dating back to 1951 and its inspiration in Dick Johnson's Harland Ross-designed RJ-5 and the first use of laminar flow airfoils. Then an account of the record setting 1,000km flight in 1964 when Alvin H. Parker released around 10:00 a.m. in Odessa, TX and landed 10 1/2 hours later on the airport at Kimball, NE at around 8:20 p.m. and much more.

In some respects inexorably connected to the Ross-Stephens gull wing and a must read if you haven't found it already!

Here is another link for the same plane.
It has since been destroyed in a high wind accident while tied down.

Tim, yes its a shame. Paul told me the news of s/n 101 two years ago and sent a list of the work needed to repair and refurbish N6390X. Its a looooong list and estimated at more than $50,000 in damages. Here is the link of the photos he took after the storm - heartbreaking.

Ouch! As you say one looooong list of to-do's to get that Sisu back airworthy, but oh-so worth it.

Sisu 1A Fine Art Print

I went ahead and finished the 1A three view for our fine art print collection and thought I'd post the preview that will be up on the web page here for comment.

Now I'm more inspired than ever to model this one. I'm thinking cold-molded plywood for the tailcone.
