220 and 270?!?! Criminy, what are you flying? The only thing I can think
of is what one person said about being past the trimmed airspeed of the
rudder, which is probably trimmed for no yaw at 220 or thereabouts. I don't
think it's to do with prop effects as this is backwards from what your prop
would do. How many Gs do you pull to start your loop?

Because of the speed? Is this occuring at faster than normal cruise? I
don't do aerobatics .. but will notice the ball slipping a little to the
left on my Tiger if I get the speed way up over cruise in a descent.
How much angle is built into the vertical stabilizer?


Cruise is 220 kts and loop entry is at 270 kts. The left rudder is
required
only when G-pull is initiated, but not during the dive. The vertical stab
has
a few degrees, not sure of the exact number.
