About this Plan

Schiffermuller. Free flight low-wing sport model. First published in Aeromodeller Annual 1948, with a span of 29in.

Quote: "Semi-scale power model. By Schiffermuller, France. Description - This delightful little semi-scale model was first demonstrated to us in 1946, fitted with an own design spark ignition engine of under 1cc featuring magneto ignition. The production of many under 1cc diesels brings it within the reach of anyone who has ever built a successful model. Both ROG and hand-launch it proved very stable and most realistic in flight. Tail and fin are simple sheet balsa construction, while mainplane is normal sheeted leading edge.

Fuselage in the original was monocoque balsa construction, but there is no reason why it should not be built as a slabsider with turtle back. Wings are fixed in place permanently, and as is usual with low wings, have fairly large dihedral. Wheels come well forward and protect the engine and prop from landing damage.

Mr Schiffermuller had fitted a very ingenious auxiliary fuel tank, which was fed from the main supply. When he was ready for a flight a stopcock cut off the main tank leaving exactly twenty seconds' running time in the sub-tank, thus saving the weight of a timer, and enabling quite a number of flights to be made without refilling.

Dimensions: Span 29ins. Chord 5-1/2 ins. Length 19-3/8 ins. Tailspan 10 ins. Mainplane airfoil section Gottingen 436."

Note this not a detailed plan, this is just a very simple general layout drawing as printed 1948, which has now been scaled up to fullsize at 27in wingspan. I am listing this here now in the hope that further and more detailed drawings will appear over time.

Update 15/06/2015: Added an alternate (still low res) version of the plan, thanks to Andrew Squires.

Alternate plan.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Hi Steve, This model has some great lines to it and could very easily be adapted to a slightly larger (or much larger) electric or gas airplane. Some minor changes in dihedral and rudder area would be necessary. The result should be a good looking, stable airplane. This may be added to my Winter project list. These 1940s and 50s era designs are very adaptable to more modern power and control systems.

Hi Steve, Just thought I'd forward you a copy of a slightly clearer plan of the Schiffermuller that Warren B on RC Groups was kind enough to email me. Keep up the good work! Kind regards,

Hi - please find attached some pictures from my Schiffermuller build for Outerzone planID: oz5683 [model photo & morepics 003, 004]. Keep up the great work!

* 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.


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.
