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. |
