Order here the construction plans for your Replica of the 7 Cylinder Radial Engine!
Please note: The plans for this engine are based on the construction plan of the 9 Cylinder Radial Engine. This is also mandatory for the reproduction.
This motor can be reproduced exactly with the help of the available construction plans. They consist of 4 DIN A3 drawing sheets representing the individual parts of the engine and 1 DIN A4 sheet. Additionally, there is a DIN A3 full view and a DIN A4 cross-section of the engine. Furthermore, a multi-page construction description with parts lists of all parts is included. In addition, supplier addresses of e.g. ball bearings, gear wheels or valve springs are also listed.
It is very precise and shows all parts in a comprehensible form.
However, a lathe and milling machine is necessary for the manufacture.

The engine is a multi-cylinder 4-stroke glow igniter, which was developed by myself. Except for the carburetors, no parts from other engines were used, each component is my own design.
The engine is air-cooled and operates with mixed lubrication (methanol and synthetic oil). It is designed as an aircraft engine, but is not based on any particular model.
