Keep in mind a 40cc engine will easily turn a 20" prop, while the 50cc engines swing 22" props. So, check your ground clearance! Anyway, good luck!
I have a ZDZ40RE on an Agressor and im not that happy with the engine. It shakes terrible and only turns a Menz 19*10 at 7200 rpm on a Krumscheid 1050 pipe. To my opinion this engine does not live to its reputation.
Now that the Brison 52 revolution engine is also advertised for in the UK, I will replace the ZDZ by that one.
