An ultra-compact high-output two-stroke motor is revealed as I lift the panel up and let it flop back on it’s retaining cables. The motor is of an esoteric square-piston design originally developed by a guy called Hossack. BAE had waited until he died to reveal their version of the design of course. Asymmetric port timing and the square section bore makes for good power in a very small package.
