The IL-155V3-2 is the Inline engine for Warbirds and scale models up to 25 kilos (55 lbs).

The IL-155V3-2 has been developed from the IL-135-2 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.

Many hours test flying this engine in different models has served to show that this engine is superbly reliable. Coupled with the optional electric starter using a brushless motor, you will find that starting is so realistic, just like the full-size Warbirds, first a very slow, slightly stuttering turning of the prop, then gaining speed slowly, she fires.

The IL-155V3-2 can be supplied with the crankshaft in the usual 180 degree setup, or with 270 degrees. With the latter, the ignition timing is like a V engine, but the balancing is rather not as good as with the 180 degree crankshaft, while the unaltered timing gives a rounded out exhaust tone.

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

·         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

·         Two 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.
