OK Lu and Helidrvr moderator looking forward to the charts, with the irrelevant types filtered out preferably.
I still maintain that the R22 is an excellent and very safe machine, conditional (as with EVERY aircraft) on flying within the book. And I insist the comparison with equivalent FW types substantiates the excellence of this product.
The critical thing to understand is whether the rotor system is sub-standard or whether impossible things are being asked for by the odd driver.
BTW conflict of interest declaration...
No financial involvement with Robinson Helicopter.
Commercially involved with BHTI.
