Propeller Chart Color Code Explanation |

|
|

|

|
|
|
|
|
|
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) |
|
|
|
|
|
|
|
|

PLEASE NOTE: |

|
|
|
The data contained in this prop chart is
based on actual measurements taken in a controlled test |
|
|
|
|
|
environment.
The test voltages used are based on a properly sized Li-Po battery for
the current |
|
|
|
|
|
draw of the motor being tested. If you are using a larger than normal
capacity battery, or a very high |
|
|
|
|
|
C-Rated battery, your actual voltages will be
higher than those shown in this chart, and this will |
|
|
|
|
|
result in higer current draw for each prop
used. You should always test your
power system with a |
|
|
|
|
|
watt meter whenever a prop is used to ensure
that you are not exceeding the recommended rating |
|
|
|
|
|
of the motor being used. The prop recommendations in this chart are
based on the motor receiving |
|
|
|
|
|
adequate cooling throughout its
operation. If your motor is being used
inside a cowl, you must |
|
|
|
|
|
provide adequate cooling to the motor and
make sure that the motor is not getting too hot during |
|
|
|
|
|
operation. |
