Sky, Sycamore et al - re Synchronization of props/engines. Alas I don't know how (or even if when down the back en route FI etc) the Herc engines were synchro'd, but it was (unfortunately) the pilot's job in the Shack, ably assisted by an instrument called a 'Synchrometer;(?) consisting of three small props, the idea of which was by minor movement of the RPM levers you could stop rotating, at which point the thrumming would stop although not the noise. As Sycamore says this was also accompanied by prayers, incantations and the odd sacrifice, but I found the imminent threat of a bash round the ears by the Flt Eng was the most compelling reason to become proficient by sortie No 2 on the OCU (MOTU)
Oh, and for further info on formation flying we left the outboards at constant power and just played with the inboard throttles to maintain position.
