guys i am a Free Flight flyer, but i know many engines we use are in the same class or league of their own.
today i took in a beautiful ST G.21/40 that has G.M. Custom engraved on it.
why i took it in you ask?.......becuase i simply cannot resist ST's.
i doubt i will ever use this engine as it doesn't qualify for any of the current events in FF.

i'm editing to let everyone know that the engine is spoken for.
i'm glad it's going to a home where it'll be appreciated.

Mike   If I remember correct Gene added two rings running in the same grove as apposed to one ring. Yours is a late model ST/40. Should make someone a very good stunt motor.
