...I'm an ex Speed and racing man so this Ringmaster has to make a noise and go fast.
The OS 40H in it was originaly built for TQR type models so no muffler and it won't 4 stroke...

You would probably like the later version of the Ringmaster Junior. Plans show it powered by a Fox .25 schnuerle.
Mine sports an Enya .09.
