Looking for info on auto pilot controls from the late 1930s to early 1940s

Aileron, rudder and elevator.

In the mk IV system the rudder and elevator were run off one gyro unit with individual servos whereas the aileron had its own discreet gyro and servo. See diagram link in post 2 above.

Which surfaces was the AP connected to? Just the elevator and rudder?

Not sure, I’ll know more once I have seen the Air publications etc for the aircraft.

Can anyone please tell me what types the 3 gauges which were used instead of the single triple reading gauge, would have been, on the cockpit photo they are listed as –
TAIL HEAVY INDICATOR.
NOSE HEAVY INDICATOR.
AIR PRESSURE GAUGE.

Cheer’s.

They look like Mk IV components to me.

Hindenburg used to have some repros of the first photo and the next 2 occasionally come up on E-Bay.

Hi John

I don’t know much about auto pilot controls, & have based my assumption on the few photo’s I have seen.
There appear to be a number of differences between the photo’s etc I have seen of MK IV controls, & the ones I am looking for.

There was a MK IV clutch lever on ebay a little while ago, but it looked different to the one in the photo, so I didn’t bid on it.

I hope to be able to arrange to view the existing drawings & hopefully one of the aircraft’s manuals before too long, & will hopefully find out the exact types etc of controls that were fitted.

I have the steering lever (middle pic) surplus, pm me if interested.
It’s available for what it cost me.

I managed to find some pictures of some of the automatic control parts, they are rather poor quality, but this is all I could find.

Not shown are the 3 gauges that are used instead of the usual triple reading type.

What type aircraft is it Bob? Mk4 is correct for late 30’s / early 40’s. I have a few spare bits.

Hi Elliott

I’m keeping it a bit of a secret at the moment, untill such a time as I have something to show “it keeps the pi55 takers & naysayers off my back”.

Could you please send me some photo’s of the spare bits ?, I can then check them against the cockpit photo I have.

Cheer’s.

Hi John

Thanks for the info. By looking at the diagram etc, I would guess that the type I am looking for info on, would be the MK III or earlier ?, as the various parts look different to the ones I can see in the cockpit photo I have “too unclear to scan”.

Hi Bob

The Stirling used the Mk IV, a general schematic of the system is here:
