I am interested in your thoughts regarding Evans Waterless Coolant For rotaries and older classic cars (1950s).
Have you had experience with the product?

People have used it in aircraft.

What is questionable is the coefficient of heat transfer between the coolant and the metal. I would test it with a thermal couple "cyl" head temperature device. Just because the coolant is temperature x does not mean the metal is being cooled.

I have a neighbor here with a Stemme motor glider who uses that in his fancy mid engine Rotax powered glider. Not without problems, tho! I think it has a turbo Rotax.
