I have a 701 from yr 2000 kit, and the plans I received state 100hp max, and came
with drawings for installation of the 912S. Still 960lb gross at that point.
You will find more than one of the 960lb gross designs running around with
floats and Continentals, which put them way over gross. The plans show a calculation
allowing over-gross operation, by derating the allowed G's during flight
to maintain the same safety margin.
The landing gear has been updated since the model you posted the pic of, to the
"tundra" gear with axels bolted directly to the monoleaf.
Current kits come with the formed windscreen, as opposed to sheet material. The
current bubble doors do add some interior room.
Wing struts are probably two-piece in the one you are considering, vs. one piece
(which initially gave some headaches due to misalignment w.r.t. fuse attach
point). Jury struts are probably the one piece wraparound version and lacking
the diagonal member.
Other changes too, just can't remember them.
Then the SP version (current kit) modified parts of the spar web, horizontal and
wing attach points, with twenty or so parts changed throughout.
Of course you asked about aerodynamic changes, so you're probably already aware
of the structural changes, and I apologize if that is the case. Aerodynamically,
the current brick may have slightly more rounded corners.. but nothing significant
comes to mind.

weight is limited to 960 lbs and there are more restrictions on engine type
and weight. The rev-4 plans had a lot of changes to the wing spars and attach
points to enable a weight increase to 1100 lbs so the more favoured engines like
912S could be used more fully. Flap travel is now restricted to 16 deg as
the heavier models dont need as much.

it will come down to what mission you have, how much stuff you need to install
and what the crew weights are.

Hello Dominique
The only aerodynamic change that I know of the 701 was on the first edition 880lb
frame , when they changed the slat angle . If you buy the old newsletter
(now on CD) you will see the changes . Try to find the serial # .
Nice find

The pictures look good. I have some 1/4" Nylatron sheet stock, that should fit
well. Thanks for the pictures.
