[Ian Jimmerson] has constructed a detailed model of a radial engine out of wood and MDF for ... feat to build something with this many moving parts that can run off an electric drill.

Turbine engines have fewer moving parts compared to radial engines, meaning they're smoother and deliver fewer vibrations (therefore less wear-and-tear) to the airframe. Aside from this ...

In the video after the break, [Brick Technology] uses LEGO to gain some practical insight into the world of piston engine design, from single-cylinder all the way up to radial twelve-cylinder engines.
