SIR,

That engine would be totally useless for RC EXCEPT if you put it in an old FF model with RC assist...which is enjoyed by some folks.
For FF it would go in an old nostalgaic ship. Search for SAM.
For CL, there is an event called Old Time Stunt where the models must be published or kitted prior to December 1952.
If you think you would be interested in any of those events, or even the challenge of getting it running, by all means keep it. Otherwise, someone would pay good bucks for it. Check prices on e*ay to get an idea of what things are going for or check with a fellow modeler who is a MECA (Model Engine Collectors Association) member to see what the "fair price" is for it.
