Agreed Sasless
Not sure how AnFi can talk about a single coning angle where the disc is stalled regardless of RRPM - the differences along the length of the blade of V squared, blade twist and aerofoil section seem to make this a nonsensical argument.
What on earth this statement
RRPM 'cancels out of the maths' when you look for stall
is supposed to mean I don't know but seems to have his hallmarks of confusion all over it.
