# How are rotary engines controlled?

Listen closely to the engine sound here.

It seems to me all rotaries continuously sound on/off. Is that a pilot application to manage the engine's torque (with the whole block rotating), or as mentioned when I brought it up in chat, due to the throttle control choosing which cylinders to fire?

(...) the Camel gives you throttle control by simply not firing some cylinders.

This question pertains to both the control (mechanism) and application (in-flight) of rotary engines. Prior to the comment I received, I always thought it was the pilot walking the lever up/down. Perhaps due to too much power and not enough fine control.
