Gary,

I believe the rule you are asking to be applied is the following FAC rule:

*F. Models must closely resemble the full-scale aircraft with respect to
outline and proportions. The general
outline of all surfaces and fuselage cross sections must be retained.
The opinion of the judges in this matter
is final!*

However that rule is only listed under Section III: FAC SCALE EVENTS
(Scale Judged / Timed)

which then goes on to say:

*1.0 FAC RUBBER POWERED SCALE (RPS)
Competition for scale-judged / timed rubber powered models, which
includes the following events:
#1 FAC Peanut Scale #3 FAC Jumbo Scale
#2 FAC Rubber Scale #4 FAC Pioneer Scale*

No cal is not included in this list. If the scale outline rule was
stated in section II, then it would apply to Nocal, Section II reads as
follows:

*II. PRIMARY RULES: All events
PRIMARY RULES apply to ALL MODELS in ALL FAC events, unless specified
otherwise in the rules for
a specific event.
*

But there is no scale outline rule that applies to all events. The FAC
rulebook use to be quite confusing in layout but the latest revisions
they did on this past rulebook make it all very clear now and easier to
understand. I think if you compare a 3 view to any published no cal plan
you will find almost all have had liberties taken on the outlines and
layout. The rule really has to be that way because some full size planes
are very difficult to model as a flat fuselage. A Spitfire has a huge
wing fillet, is that part of the wing or is it not part of the wing?
What if you built an F-18? Do the strakes count as wing or do they get
flattened with the fuselage? Jack McGillivray is the one who educated me
when I first started flying Nocal back in the mid 1980s on how to "size"
a 3 view for nocal by telling me to enlarge the 3 view until the wing
when measured from the side of the fuselage stuck out 8" not scale the 3
view until the wing was 16" span then flatten the fuselage. His method
was to flatten the fuselage first on the 3 view then scale it up to 16"
span. You gained wing area and fuselage length by doing that. I recall
he use to fly a peanut Spitfire in WWI mass launch that had flat
fuselage sides and bottom which was not scale cross section at all. The
rules did not require scale cross section at the time for mass launch
events so he made it easier to build as a box with a turtledeck on the top.
