At full power, the engine / propeller torque is relatively high. About 1/3 rudder
input is required to keep the aircraft straight. In crosswind conditions (from
the left) and when the tailwheel is off the ground, even more rudder is
required.
Hint:
Recommended climb speed in clean configuration is higher than Vy. This is
for better visibility and engine cooling, the performance loss is negligible.
