interesting. Looks like a Rossi R81 ("B81") Byron Ducted Fan engine (drum valve); two Rossi R65 RC RV ABC aero/ducted fan engines (disc rotor valve).

The R81 parts crossover to R80 drum valve marine. R65 parts crossover to R65 marine (sleeve timing may vary though).

I own quite a few of both types (R80's and R65's, all drum-valve type), they are great engines
