There's not much to learn. How much ? Here it is -

Manifold pressure is your power instrument, adjust it with your throttle
knob. RPM is adjusted with the prop knob which is the blue one. Prop knob
goes all the way forward for takeoff and landing, bring it back a little in
cruise to set the RPM based on the POH performance you want. There, you've
just learned 90% of what you need to know for the 182.

Work on the details with your instructor for your plane's specifics, like
what to do differently on the runup check.

I'm going to start training for Hi-perfromance aircraft. The plane is a
182.
I'm trying to locate info on the net that relate to hi perfromance and
constant speed props. Any suggestions?
