The Whirlwind Mk10 had an auto system for it's gas turbine engine. This could be disconnected in case of gov failure, or when the bast@@d of an instructor was feeling mean. There was then direct control from throttle on collective to engine. Needed some practice, but quite easy to do quickstops etc.
Most of the Bell 47s I flew had dreadful correlators, and all different - this meant that on some aircraft the throttle had to be opened as the lever was raised - on others, it had to be closed - great fun!

The H269 Cbi has a manual mixture control. You can lean off in flight but I never touch it! Its either In or Out!! With Fuel prices the way they are at the moment I have been tempted though!
Can you quote the procedure for leaning from the flight manual?

NOTE: (Helicopters with fuel injected engine-HIO-360-G1A)Leaning is not permitted
CAUTION....(HELICOPTERS WITH FUEL INJECTED ENGINE -HIO-360-G1A.) DO NOT LEAN.

I have one or two hours in 28As. The manual throttle is fine. You can drop the revs down a bit in the cruise to save a bit of fuel- about a gallon/hour is easy - more is possible. You can wind it up to the top of the green if you think you might need a bit of extra oomph for your next manoeuvre. It becomes totally automatic. I bet Dennis K doesn't even notice the manual throttle when he flies his display in a 28A. Correlated Enstroms have their own peculiar quirks - its not a governor. You get used to that too but for me, I prefer manual.
One of my aircraft has a vernier mixture control, EGT, CHT and fuel flow meters, calibrated injectors and runs quite happily at 9 gallons per hour. The other without all the kit runs at 12GPH!
I love watching pax who fly when I do the big pull on the lean knob.

Randomizer is it.
apart from the G2's which were quite good, i don't understand how one can use the two words correlation box and Bell 47 in the same sentence.
especially when one worked for a dude who reckoned that correlation cams, throttle shaft unis and slides were a waste of money and real pilots didn't need 'em as brand new every second day of the week, which always somehow rolled into years. They - cost too much money - or some other flippant excuse.
engineers were judged as being good; if they were an ace on the mystical secret business that went on inside the throttle box, or cam box as we called them at times.
then of course there was the secret 47 business all about the blue nut, that was issued in hushed whispers, just to help out with the power now and then, but could easily account for 45" if not careful.
but now we have this idiot turnout on the Robinson's which on a gusty day sends a 3" surge through the drive system every 2 - 3 seconds. turn it off and things are steady.

S'alright, OldB - I was only referring to the specific "Bast@@d" ones you mentioned in your post! Had it not been for all the others, I very much doubt I'd still be plugging my way towards helicopter nirvana. Such a shame that the Committee Against Aviation still deem that to happen at age 60 for those of us who don't fly with a Co, eh?

Oh Lordy - I flew the Hiller 12e, Bell47, Whirlwind 3/7/9 and never knew that there was something called a "correlator" in the system. I knew that it/they had an anticipator that probably was the same thing - but was it?
I suspect that correlator is from the land of BP bashing and therefore of little substance.
Am I right or am I older than I think I am..........?
