Construction plans model engines
All engines shown work according to the 4-stroke process and have valves for gas control, which are controlled via camshafts (or cam drums). Model engine fuel is drawn in with the air via a carburetor (Otto engine principle).
All engines work with standard glow plugs (model building trade) and model motor fuel as standard. However, it is also possible to operate it with an ignition system with a gasoline-oil mixture. More information can be found in the FAQs.
Also take a look at our Gallery, Where you will find photos and videos of our customers' engines.

Description of the construction plans
In addition to the individual part drawings for each component to be manufactured, assembly drawings, sectional drawings and exploded drawings are included. A multi-page construction manual with the most important processing steps, a parts list and proof of delivery complete the construction plans. All drawings are in A4 format.
The page size of the plans can be found in the individual construction plans (approx. 45 to 75 pages, depending on the construction plan).
The individual part drawings show the components in a 3-side view and in an isometric view. All parts are metrically dimensioned according to DIN.
Please understand that, for reasons of copyright, we only offer the construction plans in the specified paper form and not as a PDF.
If required, however, we offer 2D data (e.g. dxf, dwg) and 3-D data records (e.g. Step) for a fee.

Photos and videos of the engines made by our customers can be found in the Gallery

NEW in program: the legendary: 9-c ylinder rotary engine Oberursel URII
Superscale version on a scale of 1: 3. The exterior is exactly modeled on the original engine from 1917. Inside, however, designed with modern technology for durability and easy operation.
The engine was, among other things, in the legendary Fokker Dr. I used. The Fokker Dr.I was a three-decker fighter aircraft produced by the Fokker Flugzeugwerke in Schwerin. The aircraft used by the German Army in the First World War from 1917 onwards became famous in particular through the most successful fighter pilot of the First World War, Manfred von Richthofen (the "Red Baron"), who scored 19 of his 80 aerial victories in fully or partially red-painted Fokker triplane and also found death in a Dr. I

Sample by clicking on the image on the left
Technical datas:
• Displacement: 165 cm³ (8 x 20.7 ccm)
• Stroke / bore: 27.4 mm / 31 mm
• Weight: approx. 6.0 kg
• Speed: 1,000 - 5,200 rpm
• Propeller: 29 x 14 inches
• Overall length: 320 mm (up to propeller driver)
• Height: 144 mm
• Width: 178 mm
Execution:
• Execution of flanged reduction gear 1: 1.44
• with double carburetor
• one overhead camshaft, each with 2 ball bearings
• Crankshaft with 6 ball bearings
• closed valve gear

The most important innovations are the flanged reduction gear and the displacement increased to 165 cc (corresponds to 8 x 20, 7 cc). The size of the motor remains the same, but the performance increases by approx. 30%. The valve control is now housed in sealed camshaft housings. The reduction gear has a large spur gear with a reduction of 1: 1.44). The additional reduction gear allows the operation of prototypical large multi-blade propellers. The engine can e.g. can be operated with a 29 - 30 inch 4-blade propeller (this corresponds to approx. 74 to 76 cm diameter). The large propellers are a prerequisite for the prototypical operation of the engine e.g. in Warbird`s like the P51 Mustang. The large, slow-running propellers are more efficient. As a result, the model can be operated quieter overall without a silencer.
