The Turbo Arrow IV is a very good performer but IMO the T tail does make it a pig compared to the Arrows with the stabilator in the correct place. I haven't flown the turbo but I have flown the normally aspirated Arrow IV and the Arrow III. The T tail aircraft require more runway to get airborne and they dutch roll in turbulence. While the extra runway may not be an issue for many pilots, no amount of technique will fix the dutch roll issue. The dutch roll issue isn't unique to the T tail Arrow, other T tail light aircraft are also afflicted with this trait.
