I'd be worried about ground clearance for the prop

Being justified in crying out "Clear prop" as part of the starting sequence has a certain charm though

The three cylinder two stroke is not unique in aviation terms either. Richard Nobles ARV Super 2 built on the IOW used the same configuration 750cc Hewland AE75 engine developing 75hp. Imagine what 1.2 litres could give
