Aero

The diversity of model engineering activity is certainly shown by those who build complex aero engines. Members have built  models of rotary aircraft engines where these early designs had the cylinders and propeller fixed and the whole assembly rotated around the pistons.  Also built are scaled jet engines that can spin in excess of 100,000 rpm. Complete miniature engines have also been constructed where all components have been created in the home workshop.
