Note from negative forum member #1 :
I apologize if I offended you, but being the pedantic individual that I am :
I must say I DID watch the entire video, and that engine was so noisy I couldn't discern any clear pattern of 'clicking'
among the cacophony of other noises enough to form an opinion.
Thus, I felt compelled to point out that a video of the exact offending engine would have been a better choice.
( and I wasn't upset, only my wife has that ability )
