When flying in hot weather, check on the condition of the ESC, battery and
motor after each flight. Always let the electronic components cool to near
ambient temperature between flights. During extreme conditions, throttle
management is necessary when running near maximum levels of current draw.
It is possible to cause permanent damage to the motor, battery and ESC if in full
throttle the entire flight.

*IMPORTANT NOTE ABOUT 74% CUTOFF: This option will activate the soft cutoff
at 74% of the startup voltage or 9.2V, whichever is higher.
For example, if the battery measures 16.8 volts at startup, then the soft cutoff
will occur at 12.4 volts.
The 74% cutoff option will check the startup voltage every time you connect
the battery to the ESC. Avoid using partially charged batteries, as the system
cannot protect the Li-Po batteries if you are using the 74% cutoff and connect a
partially charged battery.
You will know the battery has reached soft auto cutoff when you hear the motor
“pulse” repeatedly. Land your model as soon as you hear the motor pulse
(indicating the battery voltage has dropped to the cutoff voltage level) to prevent
over-discharge of the Li-Po battery and to prevent sudden power loss.
