• The ESC will stop driving the motor, the main blades start to slow down and then stop rotating.
• The RPM standardization completes.
Attention:
Please calibrate the throttle range before the RPM standardization. There will be no need if you’ve carried out the
ESC/Radio Calibration when the first
time you used this ESC or you didn’t restore the settings to factory defaults after the calibration
(changing the transmitter & receiver is an exception).
3 How to Set the Speed-governing Function
Attention
：
• The best throttle amount (set in the Helicopter “Store Governor” mode) of the ESC ranges from 70% to 90%, so please try to set the
throttle amount (
set in the Helicopter “Store Governor” mode) within this range. A low throttle amount (set in the Helicopter “Store
Governor” mode) will make the ESC always function inefficiently; while a high throttle amount (set in the Helicopter “Store Governor”
mode) will leave the ESC a very small compensation space, then compensation insufficiency issue may happen and cause (speed
decrease) problem when the load is high. In that case, we recommend changing the motor or drive gear ratio (you need to
re-standardize the speed after you change the motor or drive gear ratio).
• In the “Helicopter (Store Governor)” mode, if fly your aircraft with a low performance battery after standardizing the speed with a
high performance battery may cause damage to the low performance battery.
• In “Helicopter (Store Governor)” mode, different battery packs can bring the same stable RPM only if they have the same cell count.
This won’t change even when you change the battery pack. However, battery packs with different cell count don’t have the same
effect. For
instance, in “Helicopter (Store Governor)” mode, you can`t use a 4S to calibrate the motor RPM and then use a 6S to
drive the motor, hoping it can run at the same RPM.
• You can decide the control feel via adjusting Governor Parameter P/I. In “Helicopter (Store Governor) or Helicopter (Elf Governor)”
mode, connect your ESC to a smart phone or PC, then you
can check the “throttle VS speed” chart.
1. In “Helicopter (Store Governor)” mode, you can check the standardized speed (Max. RPM) and needn’t standardize the speed
every time when the ESC is connected to the battery as in the “Helicopter (Elf Governor)” mode, so it’s more convenient. We
recommend using this mode in the condition that you’re using fixed motor, drive gear ratio and battery (with same cell count). In this
mode, only if the drive gear ratio is accurate, the main blades
’ RPM \ corresponds to the throttle amount (set in the Helicopter “Store
Governor” mode) you will get will be accurate as well. About how to “set the speed-governing function” in this mode, let’s take an
example .
•
In “Helicopter (Store Governor)” mode, connect the ESC to the LCD program box or WIFI Express module when the RPM
standardization
completes, and then find the record (as shown in Figure 1) as per the instruction about the “ data checking” process.
The value shown in the image is just an example, pleas take the value actually displayed on your LCD program box as standard.
This value is the max. electrical RPM the motor can reach at the 100% throttle.
•
Take a helicopter with single reduction gear unit as an example, with the motor poles is 10, the motor drive gear is 13T and the
main drive
gear is 120T (that the drive gear ratio is 9.3), then you can get the main blades’ RPM at the 100% throttle.
