Cardinal 177RG Hartzell Prop

moxiepilot · November 17th, 2005, 01:43

The 1974 177RG I fly has a 3 bladed, controllable pitch prop. The POH I have does not indicate how the blade pitch changes and I wondered who knows the answer.

Is it hydrolic (speeder spring / pilot valve type)
Is it pneumatic (oil / gas combo)

Any help is appreciated.
