The
prop is to small to get good performance from the motor. (Less than 50%
power) |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The
prop is sized right to get good power from the motor. (50 to 80% power) |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The
prop can be used, but full throttle should be kept to short bursts. (80 to
100% power) |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
The
prop is too big for the motor and should not be used. (Over 100% power) |

The Data contained in this Prop Chart is
based on actual measurements, taken in a controlled test environment, at an
altitude of |
|
|
|
|
|
584 feet above sea level. The test voltages used are based on the
standard output of a Li-Po battery under load, which is 3.70 volts |
|
|
|
|
|
per cell.
If you are using a battery that is larger in capacity than normal, or
has a very high C-rating, then your actual voltages will |
|
|
|
|
|
be higher than those shown in the chart, and
this will result in a higher current and power value for every prop
used. You should |
|
|
|
|
|
always test your actual power system with a
watt meter before flying your model to make sure that you are not exceeding
the |
|
|
|
|
|
recommended current and power ratings of the
motor being used. The prop
recommendations in this chart assume that the motor |
|
|
|
|
|
receives adequate cooling throughout its
operation. If your motor is being used
inside a cowl or fuselage, you must ensure that |
|
|
|
|
|
the motor receives sufficient airflow, and
does not get too hot during operation.
It is always best to use a prop size that pulls no |
|
|
|
|
|
more than 80% of the motors maximum
recommended current value to ensure safe operation under all conditions. |
