The receiver connector connects to CH2. The polarity
matches Sanwa, KO and Futaba receivers. Check the
polarity for other brands of receivers before plugging in.

１．Number of Ni-cd / Ni-MH cells 6 to 7 (7.2V / 8.4V),but there is no integrated Li Po low voltage protection!
２．Number of Li-Po cells: 2 (7.4V)
ntaneous maximum current 500A / 10 seconds, Reverse
continuous maximum current 100A (FET specifi ed)
Steady current (forward): 5 minutes / 70A, 30 seconds / 80A, 1 second / 106A
Steady current (backward): 5 minutes / 35A, 30 seconds / 40A, 1 second / 53A

7.2V (Ni-MH 6 cells)], 17 turns or more [8.4V (Ni-MH 7 cells)]
Refer to the left test sequence right after above setting is completed Push the throttle trigger forwards,quickly pull the throttle
trigger backwards & hold it. If the system keeps btaking, the throttle direction test is ok. Otherwise, if it drivers reversely, the
throttle and ESC forward direction does not coincide with each other. Change the throttle reversing switch of the transmitter,
turn off & then turn on the ESC power again will corrent the problem.

the neutral setting
starts automatically.
When the neutral setting
is complete, the ESC will
make another sound.
When the motor temperature reaches 98 ℃ ( ± 3-5 ℃ )
ESC will intermittently repeats on and off .
１．After driving, ESC is hot around heatsink and motor case, so don't touch it.
２．Always use connectors and wires with good current ratings. Replace the original ESC connector, or extend the connecting
wire to make adjustments to avoid poor connector contact, melting due to overheating, and abnormal power cutoff .
３．Connect the battery just before driving and disconnect it after driving. Also, do not solder the battery directly to ESC, use
the appropriate connector in between.
４．Always connect a power source with the correct voltage and polarity to the ESC. Using power sources with different
voltages or polarities can damage the ESC. Also, do not solder the ESC wire directly to the battery, be sure to use a
connector in between.
