SETUP
Throttle calibration should not be needed out of the box. However, in order 
to make the throttle range of different transmitters, the calibration of the 
ESC is necessary:
• Mount the ESC in an area that is well ventilated and isolated from 
vibration and shock.
•  Connect the ESC motor wires to the motor red-to-red and black-to-black.
• Plug the receiver into the throttle channel of the receiver.
• Before plugging the battery into the ESC, make sure your transmitter is 
on and the throttle trim is set to zero.
• Connect the battery to the ESC. The vehicle will be powered on when the 
battery is connected.
CAUTION: Keep all body parts and loose clothing away from any 
moving parts while the battery is connected to the ESC.
CAUTION: Always connect the ESC only to a proper power 
source that has the correct voltage and polarity. Incorrect 
voltages or reversed polarity will damage the ESC. Damage to the ESC 
caused by improper voltage or polarity is not covered under warranty.
• Test forward and reverse control using the transmitter.
To calibrate the ESC:
• Power the transmitter on and set the throttle control to neutral.
• Connect the battery to the ESC and wait 3 seconds to let the ESC initiate 
a self-test and automatic throttle calibration.
•  The ESC is ready to run when a long beep sound is emitted from the motor.
• Always disconnect the battery when the vehicle is not in use.
NOTES
• The drag brake is set to 100% from the factory.
• The LiPo cut-off is set to “ON” from the factory.
