Chimbu,
I agree 100% with you. Old wives tales get repeated again and again.
Deakins articles are an absolute goldmine for those who want to spend some time reading them. I have known John for over 10 years on the old Avsig forum and he is absolutely straight. The famous APS course is now available on-line and it is a great opportunity for those that cant spare the time or the money to go to Ada.
I have given a lecture on engine operation in the local flying club (they invited me). Maybe 5 of 50 were really listening. Very sad.
Maybe we can develop a secret handshake..
