The author discusses the theory and effect of constant-speed propellers on piston-engine airplane performance, and compares fixed-pitch versus constant-speed props, effect on thrust HP and propulsion, the comprises involved in choosing a prop, how props perform in various conditions and phases of flight, how variable-pitch props work, and why a constant-speed prop is the best choice for high-performance aircraft.

Homebuilt aircraft manufacturers are sometimes reluctant to admit that they have created a less than perfect design, let alone offer a fix. Arion Aircrafts Nick Otterback is bucking that tide; by Marc Cook.

Builders share their successes.
