Multiplex HIMAXX C 2212-0840 Instrucciones página 5

For relatively slow-flying models the propeller should have a
diameter : pitch ratio (D:P) of up to 2:1 (typically a 10" x 5" or 12"
x 6").
Model aircraft designed for high-speed flying need propellers
with a D:P of up to 1:1 (e.g. 5" x 5"). Maximum thrust is achieved
with a D:P of 2:1, maximum speed with a D:P of 1:1.
When making these calculations always keep within the
maximum permissible rotational speeds stated for the motor and
propeller.
Example: Typical power system for an indoor model with an
all-up weight of around 0.30 kg, using the Himax
C 2212-0840
From the flying weight of 0.30 kg and the type of model we see
that the input power should be (0.30 kg x 150 Watt / kg
approx. 45 Watts.
Let us assume that you want to use a 3S LiPo battery. 90% of
the nominal voltage (3.7 Volts / cell x 3 cells) is 9.9 Volts. This
gives the required current of (45 Watts / 9.9 Volts), or around
4,5 A.
As this is a model with a relatively low airspeed, you would
select a propeller with a D:P ration of around 2:1. This means:
you need a propeller of around 9" x 4,7".
Despite the careful calculations, always measure the speed and
current drain of your motor under load at full throttle. Over-
loading a motor may result in overheating and damage.
