Nice going guys - seems like a united front (Sorry Rotor Revs - I stole this from you) will help.
I have posted a thread under Rotor Heads trying to elicit a response the gurus such as Test Pilots as Eurocopter clearly want to distance themselves from the Durban 3 and we all need to help these boys. Somone must have info. Maybe one of them will get some gen somewhere and then educate the so called numsaan in SA about the finer aspects of fenestron behaviour.
Maybe there is a man in a white coat with dik brille
that has a document on his desk.
