WARNING: READ AND FOLLOW ALL INSTRUCTIONS
This manual contains instructions for safely replacing a transmitter
antenna. This replacement antenna is a key component in a sophisticated
hobby product. The instructions require basic technical knowledge and
mechanical skill. The replacement should not be attempted by children or
beginner hobbyists.
Do not attempt disassembly, use with incompatible components, or
augment the product in any way, outside of these instructions. Failure to
follow each instruction and precaution could result in a break of signal
transmission, which will ultimately lead to damage to the product, property
and/or personal injury.
Read ALL instructions. If after reading these instructions you are not
confident in your ability to replace the antenna and perform a range check,
send the antenna and transmitter, free of charge, to the appropriate Horizon
Service Center where this procedure can be performed by an authorized
service technician. Or contact a distributor in your country of service.
Note: If it is decided to submit the unit for antenna replacement, Horizon
will pay the costs of shipping and labor associated with the replacement
of the antenna. However the cost to repair any OTHER damage done to the
product may be the responsibility of the customer, to be determined at the
sole discretion of Horizon Hobby Inc.
CAUTION: Never turn the radio on when the antenna is not attached to
the module. Powering up the transmitter without the antenna attached can
damage the transmitter.

Read them completely before beginning to replace your antenna.
Items Needed:
• New antenna assembly (SPM6818) • Medium Phillips head screwdriver
STEp 1
With the transmitter power switch in the “off” position, open the
battery compartment. Remove the battery pack. Be careful not to damage
the connector.
STEp 2
Using a Phillips screwdriver, remove the 6 screws holding the transmitter
case together.
STEp 3
Carefully remove the back case half. Put it aside. Be careful not to damage
the wires.

STEp 5
Unscrew and remove the Phillips head screw from the antenna base plate
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
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 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
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 appropraite Horizon Service Center
for further assistance.
Note: If any time during or after the installation you do not feel confident
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.
