    Jim walker firecracker

    I have a Jim Walker firecraker engine how can I tell if it is a .049 or .065? I ran it with a 6x3 apc and it turned 10,000 rpm. my norvel .061 turns 17,000 with the same fuel.

    The "Firecracker" is .065 in displacement, a 6X3 prop sound adequate for it(would do better with a MAS than a APC), off course its not as powerful as a .061 Norvel!

    The "Firebee" didn't requires that much power in the 50's.Click image for larger version.
