My comments weren't meant as a "cop out".....in answer to the original question, I meant to add that the average modeler, buying a name-brand, manufactured ARF or kit, has to assume that the manufacturers have done their job in producing an IMAC-legal model.
They can do an awful lot of fudging with the 10% rule :-)

I'd be curious if anyone out there has ever been challenged to verify the scale accuracy of their model at an IMAC contest?????

Have a great Turkey Day all!
