EZ50 and EZ77 are the smallest engines in the Kolm Engines product range. They are suitable for warbirds and scale models, as well as for aerobatic models with a take-off weight of up to 16 kg. They can be equipped with an electric starter, which makes them suitable also for motor gliders. Thanks to their lean design, they fit even underneath small bonnets. They are thus the perfect drives for multi-engine airplanes and motor gliders.
