Dave,

Oops!!!!!

Considering that the plane has rudder pedals, you wrote:

That sounds like it's in an unairworthy and illegal state!  THE AILERONS MAY
NOT BE CONNECTED TO THE RUDDER PEDALS.  It's an either/or situation.  If you
have rudder pedals physically in the aircraft the interlinkage MUST be
disconnected.  It's in violation of the design and FAA type certificate
approval otherwise.

I say that very definitively because I remember Fred Weick, the designer,
discussing this issue at a fly-in when talking about his negotiations with
the CAA.

There's a choice:  The ERCO pedal design leaves the nose wheel hooked to the
yoke.  The Alon design has the nose wheel hooked to the rudder pedals.

When you get ready to buy the plane, I'd suggest you pick the mechanic who
will be YOUR mechanic and make sure he knows that.  Have him do the annual
inspection with the agreement that the cost of the annual inspection will be
deducted from some agreed "selling" dollar value which you've adjusted to
cover the annual cost.
 ________________________________

Talking about gross weight, I know too, too well the difficulties in losing
personal weight.  It's worth doing what we can, of course.  You might be
able to get the plane to lose some significant weight by the substitution of
money - I mean modern, light-weight instruments, light weight starter, go
back to a 25 amp/hour battery if it's been upgraded, light weight upholstery
if it has old, heavy upholstery, etc.

Changing the wings to fabric covered might let the plane lose as much as 40
pounds (the weighed amount of some metalized wings - yours might be
lighter).
________________________________

If you don't **need** high cruise speeds, consider changing (or repitching)
the prop to be a climb prop or almost-climb prop.  I don't see which
horsepower your engine is, whether it's a C-75 or has been converted to be a
C-85.  On a C-85, with the McCauley prop, the old terminology was:
7152 cruise
7150 normal
7148 climb
And that might have been valid if flying at gross weights of 1260 pounds.

If you go over 1260 pounds, I'd recommend these values:
7150 cruise
7148 normal
7146 climb

I had my prop repitched to 7146 and got decent climb and short field
capability and was always able to get up to 12,500 feet.  With the 7146, my
airspeed at 2400 rpm was almost exactly 100 mph - very carefully measured.
And, with the light loading of the climb prop, many (?most?) small
Continental engine mechanics say to go ahead and spin it all the way up to
redline when cruising - go with your judgment and your mechanic's
recommendations on this.  Me, I was always timid and contented myself with
100 mph even on my coast-to-coast flights.
________________________________

And, for gross weight, the tanks don't always have to be full.  Most of us
keep the entire header tank as our reserve.  With 18 gallons in the wing
tanks, my fuel burn of 5.4gph @2400 rpm gave me 3.3 hours of flight and
that's long enough for bladders most of the time.  Of course, if you go high
and lean, you can do considerably better.

(Yes, I know that telling you this is teaching grandmother how to suck eggs.
[Did Grandma know how to suck eggs?  I don't.]  But, there are lurkers who
can put this information to use.)

But, leaving one hour of fuel on the ground saves you 32 pounds on high
gross weight flights - without reducing your reserve.

And, then there's the fact that with the 1320 pound STC, you are setting the
plane to be in the exact, identical condition to what it'd be if that same
plane were converted to be a 1400 lb. gross weight 415-D (except the 415-D
must have a stainless steel panel over the header tank).  Use your own
judgment on maximizing flying safety.
