Don't Forget
p-factor, similar to lead lag in helo. As a propellor climbs, (and with a counterclockwise rotation), the descending blade has more lift than the ascending blade, which will exacerbate torque issues, requiring more rudder input. (Single). It is exceedingly rare to find Relative Wind at ninety degrees to Plane of Rotation in Propop. Each Blade is an airfoil, and experiences different Relative Airflow depending on its position in the Propellor "Disc". (When Rela. Wind is other than 90 degrees)
