P-Factor myths exploded
ps2727:
Paul, it was apparently senior moment time. I knew it was right rudder but typed left. I've changed it.
Regards P-factor in high alpha situations - when you get to the point where P-factor has any effect you are way "Behind the power curve," and while this isn't a dangerous situation in our normally overpowered model aircraft, it is a departure from normally controlled flight, so I plead its coverage under that clause.
The only "Normal" in flight condition where you have the airflow rising over the plane is during a low speed descent as on final approach, and thrust is used to control rate of descent. If you need to go around you lower the nose as you incrase power, and the airflow is again normal to the propeller disc. Again, with our overpowered models it's not necessary to lower the nose, but the power is so great that the duratuion of off line air flow is so short as to have no effect.
Okay?
Bill.
