finishing the engine

Today I put the finishing touches on the engine.  geln /curtis who built and designed this plane was a genius in light weight motors.  He first started with motor cycle engines then quickly evolved into aircraft engines.  This motor is a 4 cylinder type that is water cooled. 

the block is made out of folded aluminum.  The cylinders are made out of small tin cans.  The valves are pieced together from spare erector set parts.  The prop is sanded down from a 1"x2" board.  The radiator is made out of an old cookie tin.  The engine is wired into a magneto for the spark.  Hope you enjoy!
