Sometimes fiddly enough with just two engines.
How did you go with four. Did you have auto sync?
No auto sync but three syncroscopes slaved to one engine (can't remember which). Getting the little whizzing wheels to stay still was something to while away the hours. Your memory of 14200 rpm is spot on. The Viscounts I flew in the UK had been re-sparred, which gave some confidence. I rather liked it.
