Steering

Your transmitter is equipped with a steering rate control on the top of the transmitter just above the steering wheel. This advanced feature, usually found only on competition- type
transmitter, allows you to adjust the amount the front tires move when you turn the steering wheel. This is really helpful when you are on slick, as well as high traction,surfaces. If
your GT14B turns too sharply and / or spins out easily, try turning the steering rate down by rotating the knob counterclockwise ( to the left ). For sharper or additional steering,
turn the knob clockwise ( to the right ).

To reverse, push the throttle trigger to the braking position. After the car has come to a stop, release the throttle trigger and pull the trigger again to go reverse.

Once power on the GT14B Model Car, turn on the transmitter by sliding the switch to "On"position. If the rear wheels turn, adjust the “TH Trim” knob located on the lower right
of the steering wheel until they stop. To go forward, pull the trigger back. If you need reverse, wait for the model to stop then push the trigger forward. When going forward,
the model should move in a straight line. If not, adjust the “ST Trim” so that it tracks in a straight line without having to move the steering wheel.
After you have finished, turn the GT14B Model Car off first by sliding the switch on the ESC to the “ OFF” position. After the model has been turned off, turn off the transmitter.

If you wish to clean your GT14B Model Car, use compressed air and / or a soft paint brush to remove the dust and dirt. Never use chemicals or anything wet as it can cause damage
to both the electronics and plastic parts.

CHASSIS TUNING TIPS

GT14B Model Car has several adjustments available to match your driving need. Although there are multiple shock positions and camber link locations provided, we have built this
model with the best overall settings. The following are simple adjustments and easily maintained settings for proper operation and performance. It is advised when making any
adjustment you do so in small increments and always check for other parts of the chassis that are affected.

Camber refers to the angle to which the wheel’s flat face relative to the ground surface.
Negative Camber means the wheel is leaning towards the chassis. Positive Camber means the wheel
is leaning away from the chassis. The use of Camber angle can change the handling aspect of the car.
Maximise the tyre contact patch to the surface during cornering. By fine tuning the front and rear
camber angle, driver can tune the car’s handling characteristic to the track for maximum performance.
Camber can be adjusted by lengthening or shortening of the threaded turnbuckles or threaded rods.

Camber

Toe - in / Out

FRONT Wheels REAR Wheels

Camber angle

Toe - In (Negative Toe) and Toe - Out (Positive Toe) refers to the angle if the wheels as viewed from the top of the Chassis.
Toe - In meaning the Wheels are pointing inwards. Toe - Out meaning the wheels are pointing outwards.
The use of Toe - angle is to change the turning characteristics during initial turn in, during the turn and exit the turn.

Front Wheels :

Toe - Out will help the car to response faster at turn in. However, during the turn and exit the turn, the front end of the car will be less responsive.
Toe - In will help the car to react slower at turn in but during the turn and exit the turn will react faster.
Can adjust the Toe angle by lengthening the steering links (Toe - In) or Shortening the steering links (Toe - Out)

Rear Wheels:

Toe - Out : NEVER have Toe - Out at the rear wheels. Will becoming undrivable.
Toe - In : will help to stabilized the rear wheels and make the rear end of the car more stable.
Changing the Rear Toe - angle is by changing the car suspension hinge pin brace.

Battery Placement

GT14B Model Car is equipped with an adjustable slipper device that offers both traction
control and protection for the gear differentials. The slipper is primarily used to absorb
sudden impacts to the drivetrain when using more powerful motors and/or battery packs.
In addition it can be used to limit the amount of wheel spin when running on an extremely
slick surfaces. Adjustment is made by turning the nut clockwise (to the right) to reduce
the slip, or counterclockwise (to the left) to increase the slip. To check your setting, place
the GT14B Model Car on the ground. As you push the car backwards allowing it to roll
freely, punch the throttle. The slipper should slip no more than an inch or two as it
accelerates. With the included motor and battery it should slip just a little.

Proper gear mesh is important to the performance of your vehicle.If mesh is too loose it will cause the
spur gear to fail (strip); if set too tight it will decrease speed and the motor will overheat.
To set the gear mesh, loosen the motor screws and insert a small piece of paper between Pinion gear
and Spur gear. Push the gears together and re-tighten the screws. Finally remove the paper; the gear
should be able to rock back and forth slightly.

Setting the Gear Mesh
