Flight Mode

*Normal / Soft / Very-Soft, default is “Normal”.

Airplane/Fixed Wing / Heli Governor Off / *Heli Governor (Elf) / Heli Governor Store
1, Airplane/Fixed Wing: The motor starts to spin at 5% throttle, then speeds up quickly and reaches the full speed from standstill in 300μs. In this mode, the ESC will be enforced to set the “Auto Rotation
Restart Time” to “OFF”.
2, Heli Governor Off: When the motor starts at 5% throttle, the startup is very soft and it takes 11 seconds to reach the full speed from standstill. In this mode, if the transmitter is in NORMAL state,
then usually the throttle curve is a 45-degree slash (the start point is the lowest point / 0% throttle, the end point is the highest point / 100% throttle of the throttle range. And this throttle curve is often
used by beginners). As the start point is only 5% of the full throttle, the motor rotates slowly that greatly reduces psychological pressure for beginners, so pilots can select this mode for basic practices like
“frog leap”. In this mode, the ESC will automatically set the “Auto Rotation Restart Time” to “Off”.
3, Heli with Governor (Elf) & Heli with Governor Store：The motor only starts at 40% (or above) throttle (in governor mode, the motor won’t start when the throttle value is within 0%-40%); its startup is very
soft and needs 11 seconds to reach the full speed from standstill. Besides, it has speed-governing function (works at 40%-100% throttle). As the motor rotates quickly in “governor” mode, so it isn’t suitable
for beginner anymore but experienced pilots. In these two modes, the setting about “Auto Rotation Restart Time” comes into effect (please refer to “Auto Rotation Restart Time” for more information).
4, Heli with Governor (Elf) & Heli with Governor Store have different ways of storing target rev data. In “Governor Store” mode, the data are saved into the FLASH of the microprocessor (and the data won’t
disappear after powered off ); while in “Governor (Elf )” mode, data of the nominal target rev are saved into the RAM of the microprocessor (and the data will disappear after powered off ).
● In “Governor (Elf )” mode, the ESC will automatically start the RPM standardization & regain the target rev data after powered on.
● In “Governor Store” mode, if the pilot resets some ESC parameters (as long as re-saved values, it will regard users “revised” parameters, no matter how similar or different the new value & the old value are),
the ESC will standardize the target rev again once powered on. After the first activation of the “speed-governing” function or changed accessories (like motor, battery cells amount, gear and different type
of main/big rotor blades) on the plane, pilots need to standardize the RPM again next time.
Here we suggest pilots take the “Governor Store” mode as their rst option to avoid standardizing rev every time.
a) RPM standardization in “Governor (Elf)” mode: when the throttle value switches to over 40% from 0%, the motor starts in a
super soft way and accelerates slowly; it completes RPM standardization in 11 seconds and then enters the “governor” mode.
After changed batteries, the ESC will standardize the RPM again.
b) RPM standardization in “Governor Store” mode: when the throttle value switches to over 40% from 0%, the motor starts in a
super soft way and accelerates slowly; it completes RPM standardization in 11 seconds and then enters the “governor” mode.
After flight, please move the transmitter throttle stick to the bottom position, the motor stops spinning and the ESC will save
the standardized (target) RPM into the FLASH. After changed batteries, the ESC will read the target RPM from the FLASH, so
there is no need to standardize the rev again.
c) Example for RPM Standardization:
In this example, we take the neutral point (50%) of the throttle stick as reference points for standardizing RPM.
● Set the throttle curve (throttle value at the neutral point=50%) & pitch curve (the pitch at the neutral point is 0) in “NORMAL”
mode, and keep the throttle HOLD switch “locked” to ensure safety.
● Connect the fully charged battery to the ESC, let the ESC complete the initialization, then move the transmitter throttle stick to
the neutral point (here the throttle value at the neutral point is \ 50% and the pitch of main rotor blades is 0 degree), and then
“unlock” the throttle HOLD switch; the motor will start from standstill in a super soft way, accelerate slowly and completes the
target rev standardization 11 seconds later.
● Trial flight. If the target rev is too low, then raise the throttle curve; if the target rev is too high, and then lower the throttle curve. E.g. set the throttle curve in IDLE1 / IDLE2 / IDLE3 mode to 65% / 75% / 85% respectively to experience different RPM, and then adjust the value according to the actual situation or preference.
5, As the battery voltage decreases & the pitch of main rotor blades varies in flight, so we recommend setting the throttle curve between 60%~90% (here we strongly suggest not set the value exceeds 90%) on
the transmitter to guarantee the speed -governing effect and sufficient compensating room to keep the motor’s constant speed. If still can’t reach that target rev when the throttle value exceeds 90%, please
change the motor pinion.
6, For guaranteeing the speed-governing effect, we strongly recommend setting the PWM frequency as 32 kHz.
