BTW in fairnes I've just re-read your bit about SN24 so I read page 2 - don't even start!
Your bombshell, I predict, is this:
'Robbo book wrong b'cos stall on left side will cause roll left not aft'
- If it really is THAT then you definately need therapy! A little knowledge from a bystander is a really dangerous thing
- go and talk to a proper helicopter rotor system designer. Just b'cos all the basic text books copied each other in this mistake doesn't mean you have to follow suit .... and if it WAS that then please have the humility to say so
... and I am definatly not getting myself into this one ... someone else please tell him .. unless he wants to politely back off
first (much more respect that way)
