Description
The challenge was to make a realistic, downthrust piston engine that only activates on every OTHER revolution. VERY hard to make and is rather bug splatty because I had to interfere two groups (the flywheel thickness and the starter gear) so that it would not run out of control. This engine model starts with a motor but runs with only the piston down-thrust. #engine #four #sketchyphysics #thrust
