I do not know any without constant-speed propellers, and
I have flown quite some.

There are 3 pairs of levers for the engines: throttles,
propeller speed controls and mixture controls.

In more modern constructions (e.g. DA42NG), there are just
power levers and the engine management handles the gory
details.
