22S NO PREP DRAG: 1/10 SCALE 2WD RTR • INSTRUCTION MANUAL
BEFORE RUNNING YOUR VEHICLE
1. Check for free suspension movement. All suspension arms and steering components should
move freely. Any binds will cause the vehicle to handle poorly.
Tip:
To increase the ride height and ground clearance of your vehicle, install the included
shock spacers.
2. Charge a battery pack. Always charge the battery pack as per the battery and/or
charger manufacturers’ instructions.
3. Set the transmitter steering trim. Follow the instructions to set the steering trim/subtrim
so that the vehicle drives straight with no input to the steering.
4. Perform a Control Direction Test.
RUN TIME
The largest factor in run time is the capacity of the battery pack. A larger mAh rating
increases the amount of run time experienced.
The condition of a battery pack is also an important factor in both run time and speed.
The battery connectors may become hot during driving. Batteries will lose performance
and capacity over time.
Driving the vehicle from a stop to full speed repeatedly will damage the batteries
and electronics over time. Sudden acceleration will also lead to shorter run times.
TO IMPROVE RUN TIMES
• Keep your vehicle clean and well maintained.
• Allow more airflow to the ESC and motor.
• Change the gearing to a lower ratio. A lower ratio decreases the operating temperature
of the electronics. Use a smaller pinion gear or larger spur gear to lower the gear ratio.
• Use a battery pack with a higher mAh rating.
• Use the optimum charger to charge battery packs (Visit your local hobby dealer for
more information).
PERFORMING A CONTROL DIRECTION TEST
Perform a control test with the vehicle wheels off the ground. If the wheels rotate after the
vehicle is powered ON, adjust the TH Trim knob until they stop. To make the wheels move
forward, pull the trigger. To reverse them, wait for the wheels to stop, then push the trigger.
When moving forward, the wheels should maintain a straight line without any steering wheel
input. If not, adjust the ST Trim knob, so the wheels maintain a straight line without having to
turn the steering wheel.
1. Begin with the transmitter and receiver binding complete.
2. Set your transmitter’s throttle channel to 100% travel and trim to neutral.
3. Turn on your transmitter and connect a battery to the ESC but don’t power it on.
4. Press and hold the Set button while turning on the ESC. When the red LED begins to flash,
release the Set button. The ESC will enter programming mode if the button is pressed for
more than three seconds.
TIP:
The red LED should be flashing when the ESC enters calibration mode. If the green
LED is flashing the ESC is in programming mode.
5. Leave the throttle trigger at the neutral position, then press and release the Set button. The
red LED will stop flashing, the green LED will flash one time and the motor will make a tone to
indicate the neutral position has been accepted.
6. Hold the throttle trigger at the full throttle position then press and release the Set button.
The green LED will flash twice and the motor will make two tones to indicate the full
throttle position has been accepted.
7. Hold the throttle trigger at the full brake position then press and release the Set button. The
green LED will flash three times and the motor will make three tones to indicate the full
brake position has been accepted.
The motor will operate normally after calibration is completed.
