constant-speed propeller

The short-and-sweet version, as per Jim:
Different settings for climb, cruise, etc. will be in the POH.

Remember, going uP, Prop first; going down, throttle first.

Once airborne, RPM becomes your prop reading and manifold pressure becomes your throttle reading.

To lean, you really have to use a Engine Gas Temperature gauge. Trying to do it by manifold pressure is just not good.

PS.
BJ passed his private pilot test. Ka-ching!
