Correct - if the original was designed to fly on up to a C, then the upscale needs to fly on at least an E. We could have said "two motor mount sizes larger", but we're choosing to keep it simple.

The entire rules of the contest are posted on the NSL website, but they're patterned after "Sport Scale" rules in NAR competition -- we're not going to actually measure the entries, we're just going to eyeball them. You just need to provide some sort of documentation of the original -- an catalog listing of the original kit, the package label from the original kit, etc. You just need to provide something to show that the original rocket you're upscaling is a commercially produced rocket kit, and what it looks like.

We didn't specifially rule out entries that are themselves upscale kits -- for example, we're not prohibiting entering a Mega Der Red Max as an upscale Der Red Max. Because the static judging is going to take into account difficulty of construction, and because an upscale kit is an easier build than a scratch built, anyone who takes that approach will be penalizing themselves in the static judging -- but they can still do it that way if they want. This is NSL, not NARAM, so we're not going to get nit-picky about what entries to allow and what entries to disallow. We mainly just want people to have fun with it -- and an upscale contest provides an extra measure of fun for spectators as well.
