Can you imagine the size of a 40 to 50 HP outrunner? Worse, the size of the batteries nneded to power it. You'd need a cord connected to a generation facility.
The WW1 rotarys were not all that great, but that's what they had to work with.
The question was did the rotary engines back then develop more torque than the radials? The comparison was to the larger diameter rotating mass in the case of the outrunner vs the inrunner, and of the rotary vs the radial. Or does anyone not know? Thanks.
