In the effort to build a copy of several of the planes of my youth I'd like to build the Scientific Stuka, which I solo'ed on in 1964. Even have a brand new Wen-Mac for it. Emailed Blackhawks models but can't get through. Anyone have a copy of the plans? They aren't full size but I can fix that. Thanks a bunch!

Attached is a copy of what was printed in a newsletter for the Kits and Plans Antiquitous organization. The newsletter is called "The KAPA Kollector". In December 1998 they published the story of John Frisoli and Scientific Models and had dozens of ads and photos of those Scientific models. The plans for the Stuka show a carved "hollow log" fuselage, "shaped wing", for .020 to .075 engines. The magazine ad states this had an 18" span. Kit sold for $2.50.
That newsletter also had an issue with 44 pages dedicated to Walt Musciano in June 1997. Muscaiano tells his life story here. Also listed are all of the books, magazine articles, kit designs, magazine construction articles from this remarkable person. Also showed a number of photos and plans of many of his airplanes.
At one time not long ago, Musciano sold plans to many of his designs. I do not know if he still does that.

Keith you are the best! Think I can get what I need here. Thank You!

Try Currell Pattie at currellpattie@hotmail.com if you are looking for a scientific plan, he used to have all of them.
Also there are some at http://www.outerzone.co.uk/index.asp that can be downloaded

Thank you John. May try that too . Went to Kinkos to try downloading the file Keith sent but they can't get it off my iPhone. The phone is looking for an air printer they nor I have.

....mission accomplished...got it done at work!

Dave,
Good. I scaled up the jpg and drew a wing and stab/elev. at the correct scale.
Maybe you can get the pdf printed also . it is scaled for legal paper.
John
PS If not I can mail a copy.

I built one of those about '72. As per usual kid and dope bottle- plane wasn't done 'till the dope was gone! Pretty heavy and not much wing. A couple times whem engine, wind, grass and pilot all got together it flew o.k. - but don't try a dive bombing run - heavy plane, small wing, skinny elevator = Splatter!
The 1/2A P-40 with built-up wing / profile fuse flew a lot better - even survived some lazy 8s!
-
Most of these Scientific hollow log designs will fly OK if you watch the weight. Some will stunt OK like the Stuntmaster and golden Hawk . They all are a lot of fun.

The bent wings of the Corsair & Stuka were deal-breakers back in the day. They will probably be more viable with modern fibreglass, epoxy, and carbon fibre.

I'll use some carbon on the wing joints for sure. I hardly ever put more that two coats of dope on 1/2 a's back then-dope was very expensive on my lawn mowing salary-like .79 a 4 oz jar. Usually the most damage was trying to keep the firewalls from popping off with the Ambroid. Didn't have epoxy then. These didn't fly real super but they did fly and looked cool to a kid. I flew these in the front yard half over the street. Just pulled up high to fly over passing cars-the neighbors were used to it.
I think I built about half the Scientific line of kits. The few with built up wings always flew better but the Goldberg machines were the best fliers. Had the Top Flight combat kittens that flew quite well too.

Ah you kids, I remember using gauze, the type out of the medicine cabinet and Duco Cement. Didn' know about Ambroid until I found Charley's Hobby Shop. Used the gauze and glue for engine mounts on the 1/2As and wing joints. Some where in the shop I have most of the plans for the 1/2A planes I built back then. When I went to bigger planes, still used guaze and glue. Just bought a 4 ounce jar of SIG Red at Hobby Haven on Metcalf. Talk about sticker shock.
-
Gauze and glue were the standard until fiberglass, then epoxy, came along. Worked as well as can be expected as long as enough "fuel proof" dope was used for finish.
-
Used Fleecy sheets worked well too! And still do! H^^

Yep, I soloed on the Scientific LITTLE ACE....another one of those great hollow log kits and one which was/is quite rare. I was using an early O.K. Cub .049 and Nitro X fuel. The only LITTLE ACE I've ever seen was the one I built in 1954 and although I have been a regular buyer on EBAY for 12 years, I have never seen a LITTLE ACE kit for sale there. In fact, Scientific discontinued that kit just after I built mine...around 1956 or 57 I think. Has anyone here ever built a LITTLE ACE or seen one as a kit, built or flying? I do have a copy of the original kit plans for this plane which I got from Currell Pattie a couple of years ago and I also have a like-new condition early O.K. Cub .049.. so maybe...just maybe....... D>K H^^

Like many, many others I built various Scientific kits. With a young person's impatience, I sanded the wings just enough to get the mill marks off, never thought of additional fuselage hollowing...heck it was already hollow, and yes, used the gauze around the firewall. A few terrible coats of dope and she was ready to fly!
Mine became more complicated when I bought a NEW Space Bug Junior and had to drill a 1/4" hole for the intake, and also make sure air could get into the fuselage. Of course the old OK Cub required me to bury a small metal fuel tank in the fuselage so maybe it was a wash.
Those planes were probably heavy enough they could not loop...but then, neither could I. :-)

Ditto on not taking more balsa out of the old hollow logs. I wanted them strong enough to take the grass landings. Did do a lot of filling and sanding trying to make them look pretty. Imagine how much they would have flown had I known what I know now. Amazing the old OK Cub .049A even got them airborne.

The important part is the OK's "got them airborne". Ton's of fun with that old stuff.

Yeah, the idea of using gauze, linen hinge material, Testors glue and/or Ambroid to hold on the front end did't work too well. Flying the plane before adequate cure time didn't help either.
One field fix was sticking a toothpick, piano wire, or Allen wrench through the "log" and rubber-banding the firewall on while the glue dried. Then we realized that we really didn't need to have the glue dry and just went ahead & flew. This eventually evolved into the rubber band mounting of all Babe Bees.
