RE: Engine Torque Problem
David,
I believe you know better than my guess, which model was involved in this...
It is the Allison 'A' and not the similar looking Merlin 'C'.
...But its pilot DID give it full power, just prior to it flipping over...
It could clearly be heard in the first clip, just before the engine was permanently silenced by the crash.
And my emphasis was on what was supposed to be 'torque'... Had it been torque, that plane would have flipped over to the left.
It flipped over to the right.
