RIDGEROCK
1:10 SCALE FOUR WHEEL STEERING ELECTRIC POWERED ROCK CRAWLER

GENERAL SAFETY INFORMATION:
Never operate the vehicle in crowds of people. Serious injury may occur. Never operate the vehicle on public streets
as traffic accidents, personal injury and/or property damage may occur. This vehicle is ONLY to be driven in open
areas safe for RC cars.
Do NOT use this vehicle to chase pets or other animals. The receiver, steering servo and other electronics installed
in this vehicle are merely splash-resistant, and are not intended to be submerged in water. Do not use or put this
vehicle into water. Check the transmitter (radio controller) power level often and replace the batteries if they get low
on power. Remove the batteries from the transmitter (radio controller) when not in use. Replace with fresh batteries
if necessary. NEVER run this vehicle with low or old transmitter batteries. When this vehicle becomes stuck, do NOT
try to muscle it out with the throttle. Doing so may cause damage to the motor and/or the ESC (Electronic Speed
Controller). If the vehicle is stuck, pick it up by hand and set it down in a safe area. Check and clean obstacles
before running again. Before running this vehicle, be sure the battery connectors are plugged in firmly.
Any malfunction caused by unauthorized upgrading and modification of this vehicle, or related components, will void
the warranty.
Be careful not to touch any moving parts when the vehicle is in use, or when servicing this vehicle as this may cause
injury. To prevent excessive R.P.M. from damaging the motor, and/or the drive-train components, we suggest
reducing the throttle while in the air during jumps. Never attempt to disassemble the motor, ESC, servo, or receiver.
These electrical components have been calibrated for precision at the factory.
If you purchase upgraded parts for this vehicle, be sure to install all the parts that come in the package. For example,
if you upgrade the motor, you must upgrade the ESC and available drive-train components as well. This will limit
component damage and failure. To run this vehicle, turn on the transmitter (radio controller) first and then the
receiver. When you are done running this vehicle, turn off the receiver first, and then the transmitter (radio controller).
Always have the transmitter (radio controller) turned on any time the vehicle is turned on to prevent a runaway
vehicle. Never cut the receiver antenna, as it will lessen the radio signal to the vehicle, causing damage and/or injury.
When the vehicle is not in use, always switch off the power and unplug the battery pack. Always allow the battery to
completely cool before charging it. Never overcharge the battery pack as it will damage the battery and may cause a
fire, damage, and/or injury/death. Be sure to check the battery pack for excessive heat build-up during charging. If the
battery pack is too hot to touch, STOP CHARGING and disconnect the battery from the charger. Do NOT charge
battery pack unattended. Only charge the battery on a fire proof surface, away from anything flammable or
combustible.
Children are NOT allowed to charge the battery pack unless closely supervised by an adult. Do NOT attempt to
dismantle and modify the battery pack or the charger in ANY way.
Do NOT attempt to repair a damaged or swollen battery pack. Discontinue use immediately and dispose of the
battery pack according to your local laws and ordinances. You may buy a new battery pack to continue having fun
with your RC vehicle.

INTRODUCTION:
SAFETY NOTES:
PACKAGING:

Read this section to familiarize yourself with the features of the 3-Channel 2.4GHz radio system included with
this vehicle. Read and understand all warnings to ensure the safe operation of your radio control system.

Steering Mode Switch
Steering Wheel: Proportional steering (left/right). Turn the steering wheel to make the vehicle turn left or right.
Throttle Trigger: Proportional throttle (forward and reverse). This controls the speed of your vehicle, both forward and
reverse. Pull it to accelerate forward, release it to stop, and push it to drive in reverse.
Battery Compartment: Holds three AA size batteries to power the transmitter. (AA size batteries not included.)
Steering Trim (Front): Left Knob. Used to set the steering neutral point for the front wheels. If the vehicle veers to one
direction, while trying to drive straight, because the front wheels are not centered correctly, turn this knob in the opposite
direction until the vehicle drives straight.
Steering Trim (Rear): Middle Knob. Used to set the steering neutral point for the rear wheels. If the vehicle veers to one
direction, while trying to drive straight, because the rear wheels are not centered correctly, turn this knob in the opposite
direction until the vehicle drives straight.
Throttle Trim: Right Knob. Used to set the throttle neutral point. If the vehicle moves forward or reverse while the throttle
trigger is centered, turn this knob until the vehicle remains still.
Steering Reverse Switch: Used to change steering orientation. If the vehicle turns right when you steer left,
flip this switch.
Throttle Reverse Switch: Used to change throttle direction. If the vehicle goes backwards when you pull the trigger, flip
this switch.
Power Indicators (Red/Green):
The lights indicate the current status of the transmitter batteries. When both power indicator lights are illuminated, the
batteries have sufficient capacity to power the transmitter safely. If the green power indicator light begins to flash, the
batteries are losing power and should be replaced soon. If both power indicator lights begin to flash, the batteries have
only limited capacity to power the transmitter. In this case, the batteries should be replaced as soon as is safely possible.
Power Switch (ON/OFF): Switching the transmitter on or off.
Steering Mode Button: Used to cycle through the steering modes.

Failure to follow these warnings greatly increases the risk of damage. fire. or explosion.

We recommend that you check and maintain this vehicle after each use. Follow the suggestions below
to help ensure consistent performance of this vehicle.
•Disconnect and remove the batteries from both the vehicle and the radio.
•Inspect the vehicle for any obvious damage.
•Check the gears for wear, loose debris or broken/stripped teeth.
•Check the wheels for tightness. Tighten the wheel nuts if needed.
•Check the chassis for loose screws. Tighten if needed.
•Check the wiring for frayed or damaged wires and/or connectors.
•Check the batteries in the vehicle and in the radio controller for damage. Replace old AA batteries in the radio.
•Keep the chassis clean and free of sand, dust and moisture.
•Make sure the drive-train is free from binding (twisted grass, hair, or string) and clean if necessary.
•Clean the motor if necessary. (Never attempt to disassemble the motor.)
•Clean the body with a soft lint-free cloth.
•Store the vehicle in a clean and dry place out of children's reach. Storage conditions should be dry and cool.
Never expose the vehicle or components to heat or water.
•Check the steering servo for looseness or clicking. This component will wear out over time and may need to
be replaced.
The vehicle does not work at all:
•Be sure the radio and vehicle are both turned on.
•Check for damaged parts/wires/connectors, repair or replace if necessary.
•Be sure the radio has fresh AA batteries and the vehicle has a fully charged battery pack plugged in correctly.
The vehicle runs slowly:
•Vehicle battery is low. Charge the battery pack (after it has time to cool).
•Be sure the vehicle is geared properly and there aren’t any dirty or stripped gears. Be sure the motor
pinion and spur gear are set with correct gear mesh.
•Be sure all moving parts can move freely and clean them if needed.
The throttle works but the steering doesn’t:
•Check if the servo feels jammed, and try centering it gently if it is the case.
•Be sure the servo links are connected and not binding. Be sure the servo isn’t broken and replace if necessary.
It steers, but the throttle doesn’t work:
•Check for damaged drive-train parts.
•Be sure there are charged, or new, batteries in both the vehicle and radio.
The vehicle runs, but it is very noisy:
•Check gear mesh between the spur gear and the motor pinion gear.
•Check if there are stripped and/or dirty gears.
•Check for damaged drive-train parts.
One direction of steering travel greater than the other:
•Set the steering trim to the steering center point.
The battery pack won’t charge:
•Check to see if the battery pack or charger is damaged. Be sure the battery pack hasn’t been
discharged beyond its safe limit.
