PP-MESC Programming Instructions
IMPORTANT
Before using your new ESC for the 1
st
time please read the section “Setting the throttle for the 1
st
Time”
Features
Linear Throttle Response – Smooth and progressive throttling over the whole stick movement – easier to fly.
Quick throttle response
Auto timing – no need for manual selection.
Excellent low speed performance
Separate power supply for MCU and BEC, enhancing the ESC’s ability of eliminating magnetic interference
Self checking on power up
Low Voltage Cut Off – Protect your batteries from damage due to excessive drain.
Thermally Protected – When the temperature increases to above 110 Celsius degree, power will be lowered gradually to less than
35% of the full power, and will resume when the temperature decreases.
Signal lost Protection – Power will automatically lower to 20% or less when signal is lost for 1 second, and resume when a good signal
is received again.
Power on Protection – The motor will not start unless the throttle stick is in the off position when the power is applied
Simple Parameter Setting.

Programmable Parameters
Throttle Range: suitable for all transmitters on the market.
Brake Type: There are three brake types; off, soft, and hard.
The default is brake OFF
.
Timing Mode: There are three options: Low, Mid and High.
The default is Mid
. Low advance timing is recommended for high
inductance and low KV motors. Medium or High timing is recommended for all outrunners
Cut off Mode: There are two options: Soft Sand Hard.
The default is Soft-Cut off
.
o
Hard cut off will shut cut all power to the motor immediately the low voltage level is reached.
o
Soft cut off will gradually reduce the power to the motor as the low voltage level is reached.
Start Mode: There are three options; Fast, Soft and very Soft.
The default is very Soft Start
.
Throttle Curve Mode, There are three option; Curve 1, Curve 2 and Curve 3 (corresponds to the OFF, Gov-low, Gov-high of governor
mode in the program card).
The default is Curve 1
.
Number of Li-XX Cells; This parameter is used to manually set the number of cells in your Lixx pack. The range is 0
－
12 cells.
It is recommended not to adjust this setting unless the ESC is having problems detecting the correct number of cells in your battery
pack.
The default is 0 cell
. “0” is the automatic cell detection.
Cut off voltage: There are three options: Low, Middle, and High.
The default is Middle
.
o
Low – cut off voltage is 2.60V per cell.
o
Middle – cut off voltage is 2.85V per cell.
o
High – cut off voltage is 3.10V per cell.
Motor Rotation: Simply swop any two of the three wires over that connect the ESC to the battery, it doesn’t matter which ones.
How to Mount and Connect your ESC
The leads from the battery to the ESC (red and black) can be extended up to 12 inches (300mm) if required. If a longer run is needed
then extend the 3 wires to the motor as needed.
Add your choice of connectors as necessary paying careful attention to the polarity of the wires that connect to your battery.
Mount your ESC in a place with good cooling.
Connect the 3 thick wires from the ESC to the motor; don’t worry about the order just now.
Connect the ESC (servo type plug) to the throttle channel on your receiver.
Turn on your transmitter ensuring the throttle is in the lowest/off position and then connect the ESC to your flight battery.
Ensure nothing can touch the propeller or be sucked into it. Gently blip the throttle once to check rotation of the motor. If the motor
spins in the correct direction, disconnect the flight battery and turn your transmitter off. If the motor rotates in the wrong direction then
disconnect the flight battery and swap over any 2 of the wires that connect the ESC to the motor, the motor will now turn in the other
direction, yes it really is as simple as that.
