I hate the idea of throwing airplanes on the scrapheap. I do wonder what improvements could be made to his class of airplane with modern fuel injection and ignition. Theses airplanes run engines hard with 1930s level tech, it may be that 94 octane would work with the same basic engine brought up to the 21st century. My car runs higher boost and higher compression than I would have ever thought possible and on regular gas too!
- I remember a rental checkout for a P-Navajo that seemed 25% flying and 75% not wrecking the engines. (Not that it mattered, the insurance refused to cover rentals about halfway through the checkout process, insurance is another deadly hazzard go GA)
