Just as model airplane engines aren't all
alike, so props vary quite a bit in quality and durability from make to make.
When choosing the best prop for your plane/engine, you
should keep several factors in mind. Plane
size & weight, airfoil, thrust-to-weight-ratio, engine rpm, brake
horsepower, and other factors, like the use of tuned pipes
to boost rpm & torque, are handy things to consider when
selecting a prop size.
The nature of Pattern flying
demands agility in maneuvers, proper control of airspeed at
all times, fast response, and good thrust. Matching the
right prop to your engine and plane will make a big difference in every flight, in every
maneuver. While engine rpm and a prop's angle of pitch
will have a lot to do with the plane's speed, the prop's
diameter and pitch will determine the rpm. Power,
speed, and control should be balanced out, which means that,
for the happiest results, the plane and the engine and the
prop need to be properly matched.
APC props are designed with
such important factors in mind. You'll be able to find
the prop you need for your equipment and flight application. If you fly pattern you
already know about APC props. They've dominated much
of the market for years now. The reason is simple:
attention to detail and design. You will appreciate,
for example, how quiet the APC prop is compared to props by
other manufacturers.
