While a lower minimum weight sounds good on the surface, I believe it would
only make matters worse. People would just build 3-gram Hosler Furies!

The problem with No-cal is the 16" wingspan limit. The experts found that
giant-chord wings flew the longest--and the largest-chord design in aviation
history is the Hosler Fury, so it became dominant quickly. Since then No-cal
interest at USIC has declined steadily. No diversity of subjects equals a
stale, dying event.

A simple solution to the Hosler dilemma is to institute a maximum wing area
in addition to the 16" wing span limit. That way a 16" span Hosler would not
be legal but perhaps a scaled-down 12" span one would. Then you would have
other designs with wingspans closer to 16" (but the same wing area) flying
against the 12" span Hoslers. Of course a reasonable minimum weight would
still be in effect for all models so all would be flying at the same wing
loading.

What is the wing area of a 16" Hosler? Looks like about 16" x 8.75" chord,
according to the three view I have. This is around 140 sq. inches (sheesh!).
A 12" Hosler would be around 78 sq. inches. For comparison I just did some
rough caluculations:

a 16" Cassutt is about 93 sq inches, a Boo-Ray is 75 sq. in., and P-51D is
47 sq. inches.

What do you guys think?

Other than a lower weight limit, what would a "wing loading rule" look
like...??? I would -not- think that something more complicated than a
minimum weight would be good for the event... (maybe I'm missing
something here that I should know...)

And since we wouldn't be changing the FAC rules for No-Cal, just the
USIC rules, why would we have to get them involved...?

I actually think that everything is fine as is, other than the 6.2g...
 And it seems that others also think that 3g (nice round number...)
would work... (Personally, I would allow condenser paper covering,
but I can live with tissue...)

Does anyone know -for sure- what the procedure is for proposing and
passing a USIC rule change is...? These are non-AMA events, so they
don't fall under that procedure, but there must be something...
