The Kolm IL-230V3-3 has been developed from the IL-200-3 by replacing the steel cylinders sleeves with Nickel-Silicon plating on the original aluminum cylinders. This enlarged the bore and has resulted in an increased capacity and, of course, more power with less weight.

The IL-200-3 was the first 3-cylinder Inline engine built from the Kolm modular construction system. Otto Widlroither had test flown this engine in his P51 racer "Galloping Ghost" to the absolute limit - and sometimes beyond. The breathtaking sound of this 3-cylinder Kolm and Otto's flights with the Ghost became legendary.

The Kolm IL-230V3-3 is the Inline engine for Warbirds and Racers up to 30 kilos (66 lbs). Since 2011 this engine has been fitted to many models around the world, and has proved to be a robust and absolutely reliable engine.

The Kolm IL-230V3-3 is optionally available with a brushless electric starter motor, leaving nothing more to be desired. You will find that starting is so realistic, just like on full-size Warbirds, there is first a very slow, slightly stuttering turning of the prop, then gaining speed slowly, and suddenly she fires.

For ease of mounting in various models, besides the standard version, there is one that has a lengthened front crankshaft/crankcase, the so called "Long Edition".

For some of the most frequently encountered Warbirds we supply installation kits with a 3D printed cooling duct. A detailed set of instructions about fitting and cooling the Inline engine will assist you in achieving a perfect installation.

·         Nickel-Silicon plated cylinder surfaces, far lighter than steel cylinder liners guarantee high wear resistance

·         Assembled heat-treated steel crankshaft with Tungsten balance weight inserts

·         Crankshaft supported by five ball bearings

·         Conrods are CNC milled from high strength steel, and have a spindled bore surface for the big end needle roller bearings

·         Plain bronze small end bearings

·         A bottom-mounted camshaft is acting on overhead valves by pushrods

·         A light weight, low inertia valve train allows relatively high RPM

·         Crankcase CNC milled from high-strength aerospace alloy

·         Excellent Müller-Microprocessor-Ignition developed by Günter Müller in Germany, now made in Austria by Kolm Engines

·         Valves and pistons are manufactured at Kolm Engines in Austria on modern CNC machines

·         Three Walbro carburetors WT-225 with in sync linkage for throttle and choke

·         Engine length further adjustable by longer and shorter optional prop hubs

·         Rapid spares delivery and repair service from Germany by Toni Clark practical scale GmbH.

Each and every Kolm engine is tested in the factory and run for thirty minutes. Of this test a detailed proof certificate is supplied.
