Desirability of controllable-pitch propeller is discussed; added weight will be offset many times by great performance advantages of propeller possessing good efficiency at all conditions of flight and permitting full engine power to be developed when most necessary; few hundred hours' operation should balance added cost of controllable-pitch propellers; problems in design of propellers and construction materials.
