So I would love to have a Waco RNF. Warner engine. Fewer and fewer parts, fewer and fewer places willing to overhaul. The Wrights are getting close to the same place and a host of other engines, are worse off. What's going to happen in the future. Will these airplanes only fly with a machinist standing by? Internal parts can (maybe) be made by automotive shops. Crankshafts? Cylinders? Mags?
What is the future for these jewels of the past?
