Chainsaw Repair

You guys that like to work on chainsaws would just love the Kolm four stroke engines.

This one is 235cc, four cylinder



The Mustang. This airplane, due to its high performance, would require considerable piloting skills for it pretty much has the performance of a turbine powered model airplane.



That part of South Eastern Germany with the farm fields looks like North Western, Ohio. Some of the videos with the ski slope hills were made in SW Austria.

I was flying my 10cc four stroke plane at the local airport and my friend had a 50cc Echo powered plane. Another local UAV pilot friend showed up with his UAV friend from Phoenix that had a 200cc four cylinder USA made two stroke engine in a 1/3 scale 3D plane. My immediate impression was that the runway we were using and the available free space wasn't large enough to safely fly this plane without being a threat to the full size planes and the local neighbors.

These USA made two strokes are the most popular engines used at the flying field behind cut4fun's house. The smaller ones are more popular like the 50 and 60cc singles and second are the smaller twins. I say US made but I think the cylinders and ignitions are sourced elsewhere.
