gearup,

Along time ago a fellow modeler built a scale 60 size spitfire. It was way way tail heavy. To compensate he had a spinner machined out of solid brass. I'm talking about 1 and a quarter pound flywheel on a glow 60! Engine took like 5 seconds to spool up and same to slow back to idle. The plane never flew. Since then I've always wanted to try on with a huge rotating mass up front.
