Maybe there have been a very small number of failures of the new box, but what about the old box. The old box did fail for sure that's a fact.
Mostly due to poor servicing, but that's still a failure.
I think you guys are loosing sight of what can fail here.
Most any heli can have a catastrophic failure at some point, whether it's down to manufacturing error, poor design or poor construction - It's just happens.
If 30% of all the open tails are failing, then sure I'd start to worry, but as it stands I have 99.9% confidence it that gear box, and that's the same confidence level I have in any heli component I've built, flown and cared for. How many times do you hear on here of all the failures on all and any make of heli - of Jesus bolts failing, torque tubes letting go, heads departing, tails blades being thrown not to mention main blade failure.... The list goes on and on. "Shjt Happens"
