... Scale is scale so you don't really need the actual plans.
As I see it, if you scale your model to the wingspan on the list, you're OK.
Agreed. Keep in mind that there is a 100 point Historical Model Bonus available if one builds to nostalgia plans. Very few modifications are allowed:
"5. Historic Model Bonus:
5.1.A bonus of 100 points will be awarded for models which were designed, published, or kitted
prior to January 1, 1978. The Contest Director may require proof of eligibility, which shall be
the responsibility of the contestant. Proof may consist of dated, published plans, construction
article, photograph or advertisement from dated magazines, dated photographs, and/or letter
of confirmation of the date of design.
Plans of un-kitted, un-published designs must be made available to NCS membership.
To qualify for this bonus, models must comply with the following requirements:
5.2.Modifications:
5.2.1. No modifications to the original design are permitted, except as listed below. Any
modifications other that listed in section 5.3 which, in the opinion of the event director,
significantly change the appearance or performance of the model as it was originally
designed, shall not be permitted. This prohibition includes, but is not limited to, changes
in airfoil, changes in dimensions and use of moveable control surfaces not included on the
original design.
5.3.Allowable Modifications:
5.3.1. Landing gear may be changed in length or material, but must exit the model at the
original position.
A tail wheel may be substituted for a skid and vice versa.
Wheels may be of any diameter.
5.3.2. Leadout position may be changed from that shown on the plan.
Ground-adjustable leadouts are permitted.
5.3.3. Control travel, control mechanism location, and control mechanism may be changed.
5.3.4. Tip weight may be changed or may be adjustable.
5.3.5. Tail hook and its location may be changed.
5.3.6. Structural changes to strengthen the aircraft are permitted.
5.3.7. Building and finishing material substitutions are permitted.
5.3.8. Location of access hatches may be changed.
5.3.9. Engine mountings may be changed, and engines of different displacement may be
used."
Interestingly, my design of a scale F6F Hellcat gets zero Historical Bonus Points -- while a Goldberg Shoestring gets 100 H.B. Points.
By the way, I'm a big fan of Nostalgia Carrier.
