I have heard that the Robbos can be tricky in auto, more so the R22, and good training is important.
Winnie: I was thinking that if the blade skins debonded in flight, then the disturbance in the airflow would act a bit like a speed brake in a wing, particularly if some of the skin were protruding outwards.
Entering an auto with reduced or no power (IMHO), could allow the rotor RPM to slow down below the minimum limit.
All opinions are welcome!
Lu: Yes I agree that unapproved materials being used for these sorts of things happens a lot.
WD40 has a lot of competition in the commercial market and operators will generally use what they consider a cheap alternative if WD40 is scarce.
I’ve also heard that the scrim used in bonding can act as a wick, which draws moisture and chemicals into the bond line when the sealing surfaces erode .
Are there alternatives to the use of scrim?
