True. In a similar vein, Leroy Cox had come up with machining methods that would put his Cox engines above all others using the latest technology available at the time. What I think really killed Cox was importation of foreign engines that were priced cheaper than theirs. Their Conquest line of Schneurle ported engines were to propel them into the 21st Century, but they never took off IMO because of the competitive disadvantage due to lack of tariff enforcement. They, Fox, K&B have all passed on. This goes the same for even the US radio control equipment industry. Tom Runge at Ace R/C mentioned they could not compete because RF decks and components were cheaper to produce in Japan. They, EK Logictrol. Orbit, Kraft, and etc. vanished by the 1990's.
