EARGASMS ALL DAY. The hand crank starting mechanism is called the inertia starter, or "Schwungmasse". It works by rotating a heavy mass at a steady speed around 60 rpm. Once the proper momentum is achieved a lever is pulled below the hand crank, which engages the spinning drive pinion to the flywheel, thus turning over the engine. This video also shows the same starter on two separate BF109's as well as a flyover with a cockpit view. NO ADDED MUSIC, except the sounds of properly tuned war machines.I would highly recommend watching the entire video, but if you have no attention span I will break it down for you.1:08 Tiger Tank Startup3:40 BF109 Startup and Idle4:40 BF109 Startup and Flyover, with iconic whistling sound (so juicy)Sources: WonkaBar007, maracine anton, www.flyingmachines.tv/
