changing operating limitations

On a somewhat similar vein. As we know one of the limitations of the LSA is
that it must have a fixed or ground adjustable prop. I called the FSDO and
asked this...

The LSA rules states "(7) A fixed or ground-adjustable propeller if a
powered aircraft other than a powered glider."

Assuming the experimental-homebuilt aircraft fits the LSA rules in all other
ways can it have an adjustable prop that is, in normal operation, in flight
adjustable (variable pitch NOT constant speed) if the in-flight
adjustability is either...

A. Marked "Not for in flight use by sport pilot" or similar words

or

B. Made not inflight adjustable on the ground that cannot be made inflight
adjustable in the air?


Their answer was NO to both A (which didn't surprise me) and B (which is
what I really wanted them to say yes to.)

if one owned (or bought) an RV3, is it possible to
change the operating limitiations to have a red line of 120 knots, and a
maximum continous RPM that arrives at a speed or 120 knots?
This would potentially make it fit as a sport pilot airplane (when flown
within the operating limitations)

I have heard it discussed that this would not be allowed, from the point
of
just stating a maximum RPM. It has to be a limitation that can not be
overcome by the pilot, without major physical changes to the airframe or
powerplant.

My take is that you could put a fine pitch prop on it, and perhaps a
restrictor plate or throttle linkage that would not allow the engine to
make
full HP, so the maximum throttle setting would not allow you to go faster
than the 120 knots.

I believe (IMHO) that a major change in the prop would allow you to change
the operations limitations, but I'm certainly no expert on all of this.
Someone will give their opinion soon, I'm sure.

Will the RV 3 fit in on weight and stall limitations? You can not change
the weight, I believe.
