Is a constant speed prop worth it?
Optimized performance in each stage of flight As opposed to fixed-pitch propellers, which only operate at their optimal efficiency in one stage of flight, constant speed propellers can provide peak performance at each phase of flight, from takeoff to landing.
How much does a constant-speed propeller cost?
6,000-$8,000
That approaches the price of a brand-new prop, ($6,000-$8,000 for most single-engine constant-speed props; feathering props for twins are more expensive).
What is Hamilton Standard constant speed propellers?
Late in 1935, Hamilton Standard in collaboration with the experienced Woodward Governor Company, designed and added a simple, constant speed control mechanism which eliminated manual control and metered the flow of engine oil to and from the propeller, adjusting blade pitch to give maximum engine efficiency under all …
How much weight does a constant speed prop add?
An aluminum constant-speed prop weighs 50 pounds, but requires a prop governor, governor cable and an oil line, which brings the installed weight to 57 pounds. Forty-five pounds makes a real difference in a 1000-pound airplane.

What is so special about the Hydromatic propeller?
The hydromatic propeller was designed for larger blades, faster rate of pitch change, and wider range of pitch control than earlier controllable-pitch propellers.
What is done to cause a Mccauley propeller to feather?
Pitch is changed hydraulically in a single-acting system, using engine oil controlled by the propeller governor to change the pitch of the propeller blades. In constant-speed systems, the pitch is increased with oil pressure. In full- feathering systems, the pitch is decreased with oil pressure.
