I'm a 200-hour private pilot and was wondering about
torque and P-factor effects in high-powered aircraft,
especially warbirds.

From what I've read they could be significant,
especially during takeoff and landing, and were a major
reason for operational write-offs. Narrow-track gear
were especially vulnerable.

With my most robust flying being in a 182 about the
only experience with P-factor was with a little
pull to the left on takeoff.

In addition to P-factor, you can encounter inertial coupling between the
prop and airframe when making pitch changes (such as landing flare or
lifting the tail on takeoff) with the large warbirds.
