Coupe pilots, My flight instructor and I were trying to figure out how much of the left-turn force (during take-off) was being caused by P-factor vs. propeller precession vs. engine torque vs. propeller slip-stream. I have read that most is from the propeller slip stream hitting the vertical stabilizer. Because of this, I am guessing that Ercoupes have very little since their vertical stabilizers are out of the propeller slip-stream. Is this true? Do you'all have to push hard right rudder to keep the airplane on the center line during take-off?
Thanks in advance, -David
