I had an old Pilot Staggerwing for .30-.40 engines, with a 48" span. Beautiful scale kit... Sold it , but you can find 'em once in a great while on eBay. Expect to pay $150-$200 for it, though. There's another old kit who's manufacturer's name escapes me that is seen a little more often and goes more in the $100.00 and under range.
