CUSTOM WORK REQUIRES CUSTOM SOLUTIONS
Development of high-performance petrol engines for model planes!
The task was to optimize the cooling airflow in the world record engine. It was only through detailed optimizations that it became possible to generate 25 hp from a cubic capacity of 310 cc, setting the world speed record of 308 km/h. This knowledge was subsequently transferred to series parts. Due to the high complexity, the large number of variants and the resulting low number of units, the air ducts are still manufactured with the EVO-lizer and sold as part of a complete solution.
The EVO-lizer in use at KOLM Engines
Printouts from the EVO-lizer are used on KOLM engines in research and development. According to Kolm, this is a fantastic opportunity to work much faster and more independently than with CNC. In addition, free-form parts with high complexity are also produced for the series with the EVO-lizer.
Solutions without compromise
Special emphasis is placed on tried and tested solutions, both for standard parts and all materials! We make absolutely no compromises that could affect the quality of the engines. In this way, balance weights made of tungsten for crankshafts, helicoil inserts for highly stressed threads, aviation aluminum crankcases, built crankshafts and needle-bearing steel rods are used – so only the best of the best.
Furthermore, all heavily loaded steel parts are hardened or nitrided. In addition, Kolm engines are also subjected to a 100-hour endurance test and are performance tested. An in-house dynamometer provides exact information about the performance of the individual engines.
KOLM Engines – world market leader in large-volume four-stroke engines for model airplanes!
Johann Kolm (CEO of Kolm Engines) has set his company at the forefront of a market segment that involves designing and building 4-stroke gasoline engines for model making. A 3D-CAD system is used for construction, the data is partly entered into the CAD/CAM system, and sometimes the parts are also programmed “manually”. What makes KOLM Engines special is that everything from the development to the production of the individual parts is done in-house and all parts undergo the most precise quality controls before they are installed. Of course, a parts or measurement report is just as natural as registration using a serial number.
Every little detail counts if you want to be the best among the world elite.

Why is KOLM Engines the world market leader?
We leave nothing to chance, no compromises: “You get what you pay for!” is another one of Johann Kolm’s mottos! Kolm Engines are exclusively Austrian quality products since the entire development, the tests AND the production take place in-house. In addition, the engines are developed, manufactured and assembled by specialists who are all avid model pilots. This enormous production and development depth results in high competence, flexibility and highest quality.
Highest quality also guaranteed for purchased parts: Preferred suppliers from Austria and Germany make quality, reliability and on-time delivery possible.
