The flying mode function offers you four options for different
aircrafts. You could choose from Airplane, Glider, Helicopter
without governor and Helicopter with governor.
Flying Mode
There is a built-in Battery Management function in the
speed controller. The power cut off timing is based
on the cell number and continuous current drains of the
battery.
The battery management allows you to protect your
batteries from over discharge and moreover to extend the
lifetime of your batteries.
There are two options defined in the battery management,
one is for Li-Polymer batteries and another for
using with NiMH battery.
1. To enter set up mode and throttle calibration
Due to the signal differentiation amount different remote control brands, it is strongly recommended to run the throttle curve initiation
process whenever set up a new aircraft.
I. Shifting the throttle position to the full throttle/full speed.
II. Power on the transmitter
III. Power on the speed controller, the motor will come up with acknowledge tones ♪-♪-♪-♪-♪-♪
IV. Moving the throttle position to the minimum/stop position, the motor will come up with acknowledge tones ♪-♪-♪-♪
The speed controller recognized the exactly throttle range then optimizes the throttle curve after this progress. When finish the calibrating process, you could simply shutdown the power to leave the other settings
unchanged. If not, simply waiting for 1 second. The speed controller will enter the set up mode.
2.Battery Management
The first section of setup is battery management. This section offers 2 options for using with either NiMH or Li-Polymer battery. The motor will come up the corresponding tones as indicator.
The following is the indication with graphic reference.
o Standard discharge protection for Li-Polymer (Factory Default) ♪-♪
o +5V cut-off protection for Ni-MH ♪-♪♪
When intending to choose one of above options, simply push throttle stick from minimum/stop to maximum/full throttle after the indication tone, then pull throttle stick back to the minimum/stop position to confirm
after the acknowledge tone. You could simply shut down the power if you don’t need any further settings. If you want to skip this section and leave current setting unchanged, just keep throttle stick in minimum
position and wait the speed controller to enter next section.
3.Flying Mode
The following section is flying mode setting. This section offers 4 options. They are Airplane, Glider and Helicopter without Governor/with Governor. The motor will come up the corresponding tones as indicator.
The following is the indication with graphic reference.
o Aircraft ♪♪-♪ o Glider ♪♪-♪♪ o Helicopter with Governor ♪♪-♪♪♪ o Helicopter without Governor (Factory Default) ♪♪-♪♪♪♪
When intending to choose one of above options, simply push throttle stick from minimum/stop to maximum/full throttle after the indication tone, then pull throttle stick back to the minimum/stop position to confirm
after the acknowledge tone. Shutdown the power, and now the speed controller is ready to fly.
More about Battery Management System
This section gives you more details of the smart design of battery management in order to help you to utilize the function. Technically the power cut off timing was based on the cell number and continuous current
drains of the battery. The speed controller will calculate the timing and cut the power off with two steps. Because the last stage of each battery discharge cycle ha s quick voltage drop, such function will provide a
safe process during the operation.
1st step: enabled when the single cell reaches the low point, the motor will be forced to lower the RPM by microprocessor
2nd step: enabled when the single cell reaches the lowest point defined in the system, the motor will be completely cut off. To regain the power,
the user needs to adjust the throttle stick to the “stop” position until the battery voltage comes back to the safe level.The following are the detailed definition of each option in battery management.
o NiMH battery +5.0 volt cut off
o Li-Polymer standard discharge (Factory Default)
1st step voltage @ 2.9V
2nd step voltage @2.6V

Battery Protection
For Li-Po and MiMH Battery
Caution!!
High power motor systems could be very dangerous. High current could generate heat on wires, batteries, and motors. Always follow the instruction and use proper tools to
set up the system within safe range. Always fly at a designed field with caution even though this controller is equipped with safety arming program.
