Mike,
I know there's a bunch of guys interested in the pattern ships I used to fly back in the 80's and 90's.
They Post on RCU, probably a good place to get feedback on interest.
Thing is, most of these models had fiberglass fuselages and foam wings. Big at that time.
As for other R/C interest, it's all at RCU and other RC Forums.
Not a bad idea doing the old kits, but most guys fly ARF's.
Those CL guys interested in scale would likely be good candidates for the no longer made scale kits. A guess.
The Aristocraft kits were great. Don't know if you have to track down anyone to get the OK to make them?
I have two of the Grumman F3F Aristocraft kits. I have the plans someplace and I believe I have all the parts drawn as templates also.
Good luck.
