Note: Do not move or sway the helicopter until the red LED on the gyro illuminates solidly. This will be covered

in more detail in the next section.

• With battery power applied, and once the orange LED of the Spektrum AR6100e receiver glows solidly to

indicate a positive link to the transmitter, you will hear two "beeps" from the 2-in-1, indicating it has armed

properly. The final step of the initialization is for the red LED on the gyro to illuminate solidly.

• When you have heard two "beeps", the unit is armed and ready for flight. Use caution as both the main and

tail rotors will now spin with throttle stick input. For safety, once the unit is armed, the main and tail motors

will not spin with the throttle stick and trim in their lowest positions. However, we also suggest setting the

throttle hold (TH HOLD) switch in the on (1) position, toward the front of the transmitter, once the 2-in-1 unit

has armed. This will keep the motors and rotor blades from spinning while you handle the helicopter and

transmitter.

If you have not set the throttle hold switch to the on position, or after you set the switch to the off (0) position

toward the back of the transmitter, DO NOT advance the throttle stick until you are clear of the rotor blades

and ready to fly.

Note: If you do not hear two beeps or if you hear a constant series of beeps after battery power is applied, the

2-in-1 unit has not armed properly. A constant series of beeps indicates the throttle is set too high for

initialization. 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 you have a positive RF link between the transmitter and receiver. First, check to be sure the

transmitter has been powered on and has an adequate level of battery power. If the transmitter is powered on

and functioning properly, disconnect the flight battery from the 2-in-1, then reconnect it. Watch for the orange

LED of the receiver to begin glowing solidly, and once it does, the 2-in-1 unit should arm normally.

If your 2-in-1 unit will not arm after following the guidelines as listed above, contact Horizon Hobby's Product

Support staff at 1-877-504-0233, Horizon Hobby UK at +44 (0) 1279 641 097 or Horizon Technischer

Service, Germany at +49 4121 46199 66.

• 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 check for proper operation of the motors.

• Advance the throttle stick upward slowly, just until both the main and tail rotor blades begin to spin. DO NOT

attempt to fly the helicopter at this time. Note the direction the main and tail rotor blades spin. The main rotor

blades should spin clockwise when viewed from the top, with the tail rotor blade spinning clockwise when

viewed from the right-hand side of the helicopter. If the main rotor blades are operating in the wrong direction,

simply reverse the position of any two motor wire lead connections to the 2-in-1 unit.

• With the tail motor/rotor spinning at a low rpm, check that the tail rotor is responding properly to transmitter

inputs. When inputting a slight amount of right rudder, the tail rotor rpm's should increase, pushing the nose

of the helicopter to the right. If you are on carpet, grass, or an otherwise uneven surface, be very careful

not to allow the helicopter to catch the vertical fin when testing the tail rotor control on the ground (or during

liftoff when beginning a flight).

After confirming that both rotor blades are rotating in the correct directions, and the tail rotor is responding properly to

rudder inputs, your Blade SR is ready for flight. However, please be sure to review the following sections of the manual

BEFORE proceeding with the first flight.
