Lycoming used to have a manually controlled prop, see my post above.

While I never flew with it, I am familiar with it.

The problem, as I understand it, is that the pilot needs to he careful not to over speed the engine. In flight, you essentially have a fixed pitch prop but depending on where it is set, it could be a climb or cruise prop, or anything in between. The blade angle did not change with RPM and/or manifold pressure.
