As already covered the 'S' has a fixed pitch prop and the 'T' has
constant speed.

The S was also the beginning of the longer fuse.

The S started with frise ailerons and later had the symetricals which
all T's had. The T also came standard with 200hp (and electrical system)
and the top wing is further forward to handle the extra weight of the
prop and engine. There are a bunch of other little changes. Including, I
believe, an angled front on the turtle deck.

Hi,

I have a list of Pitts types on-line on my aerobatics website at:

http://acro.harvard.edu/ACRO

in the section [Other Aerobatics Info].

Aerotek was the name of the company that produced the Pitts for a while. the company
changed names a few times, the current one is Aviat.

Hi-

I've a few questions concerning S1 types. The -C I know has an AEIO-320,
with ailerons on the lower wing. The -S, I believe, has an AEIO-360 along
with four ailerons. Must it also have a constant speed prop to be a true
S1S? And how does the -S differ from the -T? Lastly, can anyone enlighten
me on the differences, if any, between Aerotek and Aviat?

TIA-
Wendy
