q
After confirming that the transmitter has been turned on and has an adequate level of battery
power (as displayed on the LCD screen at the bottom of the transmitter), and that the throttle stick
is in the lowest possible position, it is now safe to connect the flight battery to the ESC.
q
With battery power applied, you will hear two “beeps” once the ESC has armed properly. Use
caution as the motor, main rotor and tail rotor blades will now run with throttle stick input. For
safety, we suggest setting the Throttle Hold (TH HOLD) switch in the “On” (1) position once the
ESC has armed. This will keep the motor and rotor blades from running while you handle the
helicopter and transmitter (as long as the throttle curve values for the “Hold” flight mode are all
set to 0%, as they are from the factory).
If you have not set the Throttle Hold switch to the “On” position, or after you set the switch to the
“Off” (0) position, DO NOT advance the throttle stick until you are clear of the rotor blades.
Note: If you do not hear two beeps after battery power is applied, the ESC has not armed properly.
Please review the following:
q
Confirm that the throttle stick is in the lowest possible position and that the throttle trim is set in
approximately the middle position.
q
Confirm that the Flight Mode (F MODE) switch is set to the “Normal” (0) position.
q
Confirm that the low (L) position (POS) value for the normal (NORM) throttle curve (THRO CUR)
is set to 0%.
q
Confirm that the travel adjustment (TRAVEL ADJ) value for the throttle (THRO) channel is set to
100% in the low position.
If the ESC will not arm after confirming the details listed above, contact Horizon Hobby’s Product
Support staff at 1-877-504-0233 before proceeding.
q
Once you have placed the helicopter in a safe area, free of obstructions, and are clear of the
rotor blades, you can safely begin to power up the model to confirm proper operation and
operating direction of the motor and rotor blades.
q
Advance the throttle stick slowly, just until the motor and rotor blades begin to spin. Note the
direction that the main and tail rotor blades spin. The main rotor blades should spin clockwise
when viewed from the top, and the tail rotor blades should spin counterclockwise when viewed
from the right-hand side of the helicopter. If both sets of rotor blades are operating in the wrong
direction, power down the helicopter, unplug the flight battery, then simply reverse the position of
any two motor wire lead connections to the ESC.
Note: If the main rotor blades are operating in the correct direction but the tail rotor blades
are not, the belt driving the tail rotor may be “twisted” in the wrong direction. To correct this,
remove the tail rotor case and parts from the tail boom and pull the belt “straight” (so it is
horizontal and has no twists). Then, rotate the belt 90 degrees clockwise when viewing the
helicopter from behind.
Reinstall the tail rotor case and other parts, then, double check proper operating direction of the
tail rotor blades by spinning the main rotor blades in the clockwise direction (when viewed from the
top) by hand. The tail rotor blades should now spin counterclockwise (when viewed from the right-
hand side of the helicopter).
q
After confirming that both sets of rotor blades are operating in the correct directions, please be
sure to review the following sections of the manual BEFORE proceeding with the first flight.
