STEP 6

Carefully grasp the antenna wire near the connection point of the RF deck and pull
up while wiggling slightly. The antenna should disconnect easily.

STEP 7

Remove the two screws holding the RF deck in place with a Phillips head screw-

driver and then remove the RF deck observing the alignment of the pins so it can be

reinserted correctly later.

STEP 8

Remove the screw which connects the slotted metal base plate to the antenna
mount using a Phillips screwdriver.

STEP 9

Slide the slotted antenna base off of the antenna wire.

STEP 10

Gently pull the antenna wire tight and parallel to the antenna mount while pulling up
on the antenna housing allowing the antenna assembly to slide out of the transmitter.

STEP 11

Install the new antenna assembly in the transmitter. Feed the antenna wire through
the rectangular slot in the metal base plate.

Make sure the key at the base of the antenna mount is in the non-rectangular slot.
Use care not to pinch the antenna wire. Fasten it in place using the Phillips screw.

STEP 12

Reinsert the RF deck paying attention to the proper pin alignment. Fasten the two
screws which secure the RF deck.

STEP 13

Grab the antenna wire near the wires’ coaxial connector with one hand. With the

other hand, place the coaxial connector over the connection point on the RF board

(making sure they are properly aligned) and use your thumb or a flat screwdriver to

press the coaxial onto the connection point. (If using a screwdriver be careful not

to damage any board components.) If connected properly, the wire should swivel

slightly without disconnecting.

STEP 14

Confirm 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

transmitter is screwed back together. Reassemble the unit, replace battery 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 flying position and place

the radio in range test mode as described in the instruction manual. Press

and hold the Trainer Button to activate Range Test mode.

3.With Range Test mode activated you should have total control of the model

at 30 paces (90 feet).

4. If control issues exist, contact the appropriate Horizon Product Support

Department for further assistance.

Note: If any time during or after the installation you do not feel confident-
about the installation, please send the replacement antenna and transmit-
ter to the appropriate Horizon Service Center where this procedure can be
performed by an authorized service technician.

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.
