The Flying Sub from Voyage to the Bottom of the Sea is about to be released by Moebius Models in 1:32 scale. That makes it just under 14 inches across, about the same size as the Lunar Models kit, and a candidate for RC conversion. It is due out in February 2009. CultTVman's Hobbyshop and Tower Hobbies are both taking pre-orders at this time at very nice (IMHO) prices. Photos of the test shot can be seen here: http://www.culttvmanshop.com/shop/product.php?productid=16936&cat=263&page=2
BigDave, you need to keep sanding!
