Yes, that's exactly what he's saying, because he wasn't aware of the effects of P-factor.

No guys, i am aware of this effect you call the P-factor, my english isn't good enough and i didn't knew it before you mention it. I tried to take off without any rudder because to test the plane and the TO assist, for an experience to see what would happen.

Thanks to you, i know i don't have any pedal problem, so i'm going to apply your advices and use the rudder and slowly adjust the throttle.

Thanks

Actually, P-factor only comes into effect once the plane picks up speed (the exact cause for P-factor is that while the plane is in 3 point attitude, the left and right side of the prop disc experience greatly different angles of attack and this causes one side of the disc to produce way more thrust). Yawing at low speed is caused by the helical slipstream hitting the rudder, plus the inherent instability of the taildragger design (center of mass behind the main wheels).

Huh. I thought "P-factor" included the helical slipstream effects.
