The Kolm EZ-50 is the smallest Kolm four stroke engine. It is very suitable for Warbirds as well as other Scale and aerobatic models with an all up weight of up to 11 kg.
The Kolm EZ-50 is available with a brushless electric starter, making it very suitable for powered gliders.
The brushless engine starter is so realistic, just like the full-size Warbirds, with a very slow turning speed, slowly accelerating, and then firing. The relatively narrow construction with the low weight allows this engine to be fitted under rather small cowls with ease.
The EZ-50V3 can be supplied as turningclockwise or anti-clockwise.
