Receiver
There	is	no	adjustment	required	of	the	receiver.	Please	note	the	different	slots	for	
connection.
The	bind	slot	is	used	to	bind	the	transmitter	to	the	receiver.	The	bind	process	
teaches	the	transmitter	the	unique	GUID	ID	of	the	receiver.	Although	the	
transmitter	and	receiver	come	bound,	below	are	the	steps	to	rebind	your	
transmitter and receiver should the need arise.
Rebind Process
1.	Ensure	the	transmitter	and	vehicle	are	both	turned	off.
2.	Using	the	supplied	Bind	plug	(which	looks	like	a	standard	servo	plug	with	a	
short	wire	loop	installed),	insert	the	Bind	plug	into	the	receiver	slot	labeled	
BIND.	
Note: You do not need to remove any other plugs to rebind.
3.	Connect	a	fully	charged	battery	to	the	EC3	connector	on	the	ESC.
4.	With	the	Bind	plug	installed,	turn	on	the	vehicle.	Notice	the	receiver	LED	is	now	
blinking.
5. Turn on the transmitter. You will see a similar blinking LED under a translucent
cover on the back of the transmitter.
6. Both the receiver and transmitter LEDs will stop blinking and be on solid,
indicating they are bound.
7.	Turn	off	the	vehicle	and	then	the	transmitter.
8.	Remove	the	bind	plug	from	the	receiver.
9.	Turn	on	the	transmitter	and	then	the	vehicle	to	ensure	operation.	If	the	
transmitter	does	not	control	the	vehicle,	repeat	steps	1	–8	above.	If	after	
several attempts you are unsuccessful, please contact Horizon product 
support.
Receiver Antenna
Using	your	fingers	gently	straighten	the	antenna	wire	to	be	close	to	vertical	from	
the chassis for the best radio reception.
Factory Settings of Radio/ESC
The	Electronic	Speed	Control	was	calibrated	together	with	the	radio	system	at	the	
factory.	When	you	turn	on	and	run	the	XXX-SCB	for	the	first	time,	you	may	need	
to	slightly	adjust	the	Throttle	Trim.	If	the	vehicle	creeps	in	reverse	or	in	forward,	
make	a	fine	adjustment	to	the	Throttle	Trim	knob	on	the	transmitter.	Sometimes	
the bumps and bounces of transportation can slightly alter the settings.

Tuning, adjusting & maintaining Your Vehicle
•	 Examine	your	vehicle	on	a	regular	basis.
•	 Use	a	brush	to	remove	dirt	and	dust.
•	 Look	for	damage	to	the	suspension	arms	and	other	molded	parts.
•	 Re-glue	the	tires	to	the	wheels,	if	necessary.
•	 Use	suitable	tools	to	tighten	fasteners.
•	 Make	sure	the	camber	and	steering	linkages	are	not	bent.	Replace	any	bent	
linkages.
•	 Adjust	the	Toe	and	Camber	settings,	if	necessary.
•	 	Remove	the	shocks	and	inspect	them	for	damage.	Rebuild	the	shocks	if	oil	is	
leaking.
• Inspect electronics and batteries for exposed wires. Repair exposed wires with
shrink-wrap or replace the wire.
• Make sure the ESC and receiver are secure on the chassis. Replace the
double-sided tape, if necessary.
• Power on the transmitter. If the green LED is dim or off, replace the AA
batteries in your transmitter.
• Check the spur gear for wear.
service/Repair
Radio/Speed Control & Motor
If	any	problems	other	than	those	covered	in	the	troubleshooting	section	arise,	
please	call	the	appropriate	electronics	service	department.	They	will	be	able	to	
give	the	problem	additional	specific	attention	and	provide	instructions	for	the	
solution.
Maintenance
If	any	questions	other	than	those	covered	in	the	troubleshooting	or	maintenance	
sections arise, please call the appropriate Horizon product support department.
Cleaning
Performance	can	be	hindered	if	dirt	gets	in	any	of	the	moving	suspension	parts.	
Use	compressed	air,	a	soft	paintbrush,	or	a	toothbrush	to	remove	dust	or	dirt.	
Avoid	using	solvents	or	chemicals	as	they	can	actually	wash	dirt	into	the	bearings	
or	moving	parts,	as	well	as	cause	damage	to	the	electronics.
