I have a fair amount of time in the back seat of the SF-34. From a
CFI's, (at least this CFI), point of view, it's easier to fly than the
G103 in that the controls are more haromonized and it does well in weak
lift. At speeds above about seventy knots it seems to out run, (albeit
slowly), the G103. The useful load is better as most 103's in this
country have less useful load by virtue of their age and damage
history. From a student or at least a front seat point of view, there
is a bit less foot room than the 103 as the nose is more pointed. The
SF-34 ground handles better than the 103 because of the manner in which
it is so easily balance on the main wheel. There is quite a lot of
room in the back seat and I even need some extra cushions, (I'm 5' 10")
in order to reach the stick in it's full forward position. There are
only two in the US that I know of and the one I've been flying is at
the Moriarty airport in NM. All-in-all, the SF-34 is a lot of bang for
the buck.
