Mixture control useage
Just to confirm my previous notes relate specifically to the Enstrom marque and the 'more aware' pilot.
Robinson 'carburettor' models should be operated as Choppergod advises.
For the most efficient use of the Enstrom HIO 360 C series engine, Lycoming recommend the procedure I specified.
Mixture leaning is not a 'no-go' area. In many areas it is mandatory. Try taking off at Nairobi Airport with a 'full-rich mixture' Piper Aztec to discover why.
