I'm trying to do some research on an add placed in the book : Auto engines for Exp. aircraft by Richard Finch 1986 era and on page 175 there is an add from Gyrodynamics Systems offering plans for corvair and VW Planetary gear drive's and also Chain drive's. The company was located at Redlands, CA. It apears the company supplied All parts and material. Are these systems still active in aircraft ? Has anyone used the plans for Duel plugs in the corvair heads ? I'm working on my FWF and would like any information if you have any . Don
