Another FOX engine.

This is just to satisfy my curiosity. Can anyone tell me what this engine is? I was told that it was a .36X, but it isn't like any of the .36Xs that I have had my oily hands on in the past.

Just wondering.

That's one of Duke's foul ball swings. Occasionally seen as an "RX", it was used some for profile Navy Carrier, with throttles from other makers substituted for the Fox unit. I've forgotten the exact time frame for its production, probably late 1970's, but when sold with the plain trumpet intake like yours, it was described on the box as a "stunt" engine. I never saw one used that way, myself, with any type intake.

There was actually a version of this engine marketed as Stunt.

Big Art Adamissin told me that he had tested one in a profile stunt ship, and that it ran pretty well. The major problem was the exhaust location.

Big Art gave me one a number of years ago that he modified, it has a ringed piston.

The exhaust came out the back and into a converted fuel tank for a muffler. It was in the late 70's when the whole world decided that it was time to put mufflers on engines. Seems really weird now, but I still remember buying an engine and trying to decide what after market muffler to buy for the thing, and how to attach it. Then OS started putting them in the box, wow, that's up to 40 dollars left per powerplant purchase.

Just when you wish you were around for all the weird stuff that happened in the early days of this hobby, someone goes out and makes new weird stuff for you to enjoy.
