1. VERY IMPORTANT: Before turning on the transmitter, set the throttle stick as well as its
trimmer to the lowest (power off) position, and the trimmers of pitch, yaw, and roll stick are
set to neutral position.
2. Verify the position of the servo reverse switches.
3. Turn on the transmitter then.
4. Connect the battery pack to the control-box and you will see the LED blinks red first. Wait a
few seconds until it lights green after blinking green for a moment.
The LED keeps blinking if the throttle stick and/or the trim lever is not in power off position!
5. Push the pitch stick forward and backward and the roll stick left and right to check if the
swashplate works correctly.
6. Holding the helicopter in your hand to make adjustment
1. Hold the helicopter at its C.G. point with your fingers. Make sure that the fuselage is level.
Allow the machine to turn freely if any force is applied to it.
2. Push the throttle stick slowly forward. The lower rotor will rotate before the upper rotor.
Gradually push the throttle stick 1/3 way to its full power position. The helicopter will begin to
tilt in some directions. Be careful not to let it go.
3. Determine by observing and feeling if the machine is attempting to tilt forward / backward or
left / right. If the fuselage is twisting to the left, push the yaw trim lever on the transmitter a
little to the right, and vice versa. If the nose of the machine is tilting downward, pull the pitch
trim lever backward a little, and vice versa. If the machine is rolling to the left, push the roll
trim lever a little to the right and vice versa.
4. If the model is trimmed in a way that it will not turn or tilt in any direction pull the throttle stick
back to its power-off position.
Disconnect the battery pack from the control box.
Switch off the transmitter
5. If necessary, recharge the battery pack before flying.
