Fixing Roll

[bongodriver]

torque is not really an effect purely of air resistance, it is more to do with inertia, the flywheel is a heavy mass (just like a prop) and causes resistance to the power of the engine, that energy needs to find its way somewhere, inevitably it will cause the whole engine block to rotate in the opposite direction, I know.. I've seen it, an engine on a static test bench being revved will lurch in the opposite direction of crankshaft rotation, essentially we are in agreement on this effect but with slightly differing perceptions on its cause.

propwash is a factor as soon as the power is applied and is harder to control at low speeds because the aerodynamic controls havent got a 'bite' on the airflow
