STEP 5

Unscrew and remove the Phillips head screw from the antenna baseplate and the

Phillips head screw from the antenna housing. Notice that of the 3 holes in the

base plate, the antenna routes through the rectangular hole.

STEP 6

Slide the antenna assembly out of the top of the transmitter.

STEP 7

Reassemble the new antenna assembly and the shaft. Route the coaxial wire

through the shaft until the wire exits the rectangular opening at the base of the

shaft. Align the shaft with the antenna housing until the Phillips head screw holes

line up. Be careful not to pinch the antenna wire when reinserting the shaft. Then

install the Phillips screw on the antenna housing.

STEP 8

Install the antenna assembly in the transmitter. Feed the antenna wire through

the rectangular opening in the metal baseplate. Make sure the key is in the non-

rectangular slot. Use care not to pinch the antenna wire. Fasten it in place using

the Phillips screw in the center hole.

STEP 9

Install the antenna connector on the RF module. Precise alignment is needed

so the two snap together. Carefully align the connector and press in place until

it clicks. Ensure proper connection by a slight “side-to-side” movement of the

antenna wire.

STEP 10

Conﬁ rm the installation was done correctly by checking that all wires, screws

and other components are back to their original position with the new antenna

installed. Check to ensure no wires are kinked or will be pinched when the trans-

mitter is screwed back together. Reassemble the unit and perform a range check.

Range check procedures:

1. With the model resting on the ground, system powered and model secured,

stand 30 paces (approx. 90 feet) away from the model.

2. Face the model with the transmitter in your normal ﬂ ying position and

depress and hold the bind button on the back of the transmitter. This causes

reduced power output from the transmitter.

3. You should have total control of the model with the button depressed at 30

paces (90 feet).

4. If control issues exist, contact the appropriate Horizon Service Center for

further assistance.

Note: If any time during or after the installation you do not feel conﬁ dent about

the installation, please send it to the appropriate Horizon Service Center.

WARNING: ENSURE FUTURE ANTENNA SAFETY - Do not attempt to use the

antenna to bear any weight, pick up the transmitter by the antenna or alter

the antenna in any way. If the transmitter antenna or related components

become damaged the output strength can be severely impeded which will

likely lead to a crash, injury, and property damage.
