@737ngpilot and others
Ok. Firstly could you please explain why D2 lies farther away from the fuselage as compared to D1 during a take off roll on the ground (not when in the air).
As far as i know the assymetric blade effect or P-factor is when they down going peopeller travels through a greater distance than the up going propeller i.e the down going prop produces more thrust than the up going one hence you have different thrust lines. But this normally occurs only after a take off or for tail draggers during a take off run. I think the assymetric factos that I am refering to does not happen for a normal multi engine prop aircraft during a take off roll.
(please correct me if I am wrong)
Thanks.
