About this Plan

Fieseler Storch. Scale RC gas model of the German STOL aircraft. Scale is 1/4, for a span of 140in. Powered by a Laser 300 V-twin 4 stroke 50cc engine. Zipfile of 3 x jpgs at 72 dpi.

Note this plan is available as a free download from designer's own website at
http://www.paoloseverin.it/Fieseler/Fieseler%20Download/FieselerDownload.html along with a 14 page build article (in three languages) that explains the construction. Also there is a 48 page photo-album pdf download, too.

Quote: "I had heard many stories on the Fieseler Storch, but I had never seen one, other than in world war two old movies or in books and magazines.

Being a lover of slow flying, of the very slow landings, I got hooked by listening to the many legends about it and became for me imperative to build one.

I therefore started to get acquainted so as to have a good three views drawing, buying some from the www.bobsairdoc.com website, but among the three or four three view drawings that I received from the USA there were not two alike. I decided to stick to the most realistic one. Still on the internet on the site www.hinkleymall.com/storch.html, I purchased for $40 (you don’t go broke just gambling) a big book containing more than 200 copies of original drawings from the Fieseler factory.

Most of them were elevation views of as built details, not too useful for the project, even though interesting. However were included very precious drawings of the wing original airfoil, with the slats on the leading edge, the flaps and ailerons showing precisely the hinge points, in addition to the test results in the wind tunnel.

I had noticed some intriguing details of the fuselage steel structure which fascinated me. I then began to 'nurture' the project. I was pondering on how to solve this or that detail, trying always to find solutions that were as close as possible to the original one, but the picture that kept coming back to my mind was the steel structure of the fuselage. I started to evaluate if it was possible to build the fuselage like the one of the full scale airplane, some time before I had found small tubes in stainless steel in various diameter size , thick only 2,5 tens of millimiter. After some calculation i was amazed: a 1/4 scale fuselage over 2m long would have weighted a little over one and half kilogram. I could not believe it. I recalculate but the result was the same. So I said 'same as the full scale or nothing! and I decided to start. One hand on my heart and one on the wallet, I ordered over 40m of small tubes in different sizes,worth about Euro 300, from the company Castiglioni of Milano (see www.castiglioni-tubi.it) . The stuff arrived right before the Christmas holidays during which I started to work.

The project. After scanning the 3 view drawings I began to simulate various scales on the computer and i decided to go with 1/4 scale. The model that came out had a wingspan of 354cm, length 242 cm and 175 sq dm of wing area. A true beast! Just for precaution, before moving on, I measured out the car and calculated that by removing the stabilizer probably was going to fit..."

Update 26/11/2018: Added 3rd page to the zipfile, showing fuselage structure, thanks to Pit.

User comments

Have always LIKED this airplane and would love to build this model. It seems to lack any detail on fuselage formers, though, so it's hard to determine fuselage cross sections at various stations front to rear. Is there another plan sheet that's missing ? Any additional detail on a mechanism to open leading edge slats in concert with trailing edge flaps (maybe a cam arrangement to add slats at >20 degrees of trailing edge flaps) also would be useful/helpful. Or I could set up slats on a separate channel, perhaps. I would plan to make it a 6-channel R/C model - rudder, elevator, ailerons, engine speed, flaps/slats and lights. Many thanks for any added info.

Hi Geoff, I think you're putting the cart ahead of the horse as the Fi 156 slats were fixed. No extend/retract mechanism, just bolted in open position. Regarding fuselage formers, the original had none of these, the fuselage was welded metal tube - I'm not sure of the material right now - and Mr Severin followed the original.
Miguel - 26/11/2018
Yes, the fuselage is welded from stainless steel tubing, forming an exact scale replica of the full size machine. Without using any jig, or indeed any 1:1 drawings, according to the article. It's an incredibly skilful and complex build, using techniques that the rest of us would simply describe as magic. So...no, there are no formers. Although he does sell a complete kit, so there must be some way of replicating the build.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
