Wildcat prop question

[hahnej]

Noticed that the prop hubs on Wildcats are kinda unique. What is the difference between it and a standard-looking HS prop setup?

WWII most have Curtis Electric Props.

The Curtis Electric on the Wildcat adjusts prop pitch electrically. Most other types use engine oil pressure for prop pitch adjustment.

P-38 and P-40 are other examples of aircraft using the Curtiss Electric prop, but since those have spinners it isn't so obvious.

The Helldiver, Marauder, C-46 and many Thunderbolts also originally had versions of the Curtiss Electric prop. Many of those have been subsequently converted to HS props as parts are more readily available.

I always thought the prop on the Douglas AD-1 / A-1 Skyraider series were some of the strangest looking - there was no "dome" of any kind...

Aeroproducts Prop. Hydraulic like the ham Standard.

Aeroproducts props were hydraulic, but they had a dedicated pump and oil supply. They did not use engine oil pressure (or even engine oil) to operate.

Is it for all Aeroproducts props, or for the aircraft types above only?

All Aeroproducts were this way as far as the WWII and postwar types.
It was a fully independent system that featured the only connection to the engine was attachment onto the prop shaft, the oil feed passages were blocked off, and the control lever connection from the cockpit via the control linkage.
All functions and components were internal on the prop.
Google General Motors Aeroproducts, some good stuff on the net.
