The following is a description of the nomenclature used
for
APC propellers.
The size of each propeller is identified
by
two numbers,
separated
by an 'X',
that are stamped on the propeller blade.
The first number represents the
diameter of the propeller in inches. The second number is the pitch in inches
per revolution.
APC propellers are by default assumed to be of a standard type (Sport),
unless modified for a specific characteristic or purpose.
Sport
propellers
are intended for
use with
internal combustion engines.
The letter(s)
following
and/or
preceding
the propeller size indicate the type
and/or
modification.
The letter(s) that precede the propeller size in the part
number are
identified below.
The various
propeller
types
and modifiers
are
described as follows:
Type:
E
Thin Electric or Electric (electric only)
F
Folding Blade (electric only)
MR
Multi-Rotor(electric
only)
SF
Slow Flyer (electric only)
R
Reversible ESC (electric only)
Modifier:
B

(precedes
diameter

number)
B4 Bundle Pack (2CW and 2 CCW propellers)
D Durable
Material(precedes

W
Wide (chord)
N
Narrow (chord)
NN
Very Narrow (chord)
PN
Pattern
P
Pusher (or
reverse rotation
for electrics)
ST Self Tightening
C
Carbon
Material (40% Carbon/
60% Nylon by weight)
()Reserved
for Special Notes
A combination of the above
maybe
used. For example: MRP
is a reverse
rotation multi-rotor
propeller.
If there are no letters behind the propeller size, then it is a
standard
rotation
Sport propeller.
Although sport
propellers are intended for use with internal combustion
engines,
they
can
also
be used with electric motors.
Electric propellers are intended for use with electric motors only.
