Frans,
As with all things in life you have to listen to advice from 'experts', l am
sufficiently
convinced that the LAA selected the instructor for the Rotax course
on the basis that he knows his stuff.
At the course we examined parts and the instructor also gave a description of
exactly what happens during all phases of operation of the engine.
He showed parts that had premature wear due to oil starvation.
As an aeronautical engineer l took the advice given by that instructor and act
on it. If you want to do something else that is fine by me.
Put simply, if a component (say a cam) has oil on it and it is turned against
other
parts the oil WILL be disturbed. If the oil is disturbed some of it may
vacate to another place (eventually in the tank if cranking).
I appreciate that you have your own opinion, my opinion and the LAA course
instructors
advice is - do not hand crank unless there is a good reason to do so.
Maybe we can meet at EHHO and chew the fat........
