SAFETY PRECAUTIONS

When these safety precautions are followed, the Vendetta SC will provide years of enjoyment. Use care and good sense at all times when operating this radio controlled truck. Failure to use this vehicle in a safe, sensible manner can result in injury or damage to property. You and you alone must ensure that the instructions are carefully followed and all safety precautions are obeyed.

• Do not operate the Vendetta SC near people. Spectators should be behind the driver or at a safe distance away from the vehicle.

• Make sure to read the instructions included with the battery and charger before charging the battery.

• Do not leave any charger unattended during charging. If the battery or charger become hot at any time, disconnect the battery from the charger immediately! Failure to do so may cause permanent damage to the charger and battery and may cause bodily harm or property damage.

• Do not cover the air intake holes on the charger during charging. This may cause the charger to overheat.

• Do not allow the electronic speed control (ESC) or other radio equipment to come into contact with moisture. Water can cause electronics to short out and can cause permanent damage.

• Always turn on the transmitter before turning on the electronic speed control.

• Always turn off the ESC before turning off the transmitter.

• Allow the motor and ESC to cool before each run.

HELPFUL HINTS

• Avoid working over a deep pile carpet. If you drop a small part or screw, it may be difﬁ cult to ﬁ nd.

• Place a mat or towel over your work area. This will prevent parts from rolling off and protect the work surface.

• Avoid running the truck in cold weather. The plastic and metal parts can become brittle at low temperatures. In addition, grease and oil become thick, causing premature wear and poor performance.

• Test ﬁ t all parts before attaching them permanently.

• Slowly pull on the throttle trigger. The Vendetta SC should slowly move forward. If the truck goes in reverse, move the throttle reversing switch on the transmitter. The throttle trim knob may also need to be adjusted to find neutral.

• The receiver should be factory bound to the transmitter. However, if you ever need to bind, follow these steps:

1. Turn on the transmitter.

2. Turn on the receiver via the switch on the ESC. If the

receiver is not bound, the LED light will not be on.

3. Push and hold the bind button on the receiver until the

light glows red.

4. Release the bind button.

5. If the binding is successful, the LED will flash once and

then remain ON.

ALWAYS CHECK THE RADIO

NOTE: If you do not wish to change the ESC settings, simply wait for the red light

to stop flashing (about two seconds) before moving the throttle trigger.

1. Center the throttle trim adjustment and turn on the transmitter.

2. Move the switch on the ESC to the “OFF” position and connect the battery.

3. Lift the chassis so its wheels are off the ground.

4. Turn on the ESC. It will “beep” once and the red light will begin to flash indicating the ESC is in set-up mode.

5. Program the ESC by moving the trigger to the full speed position, then to the full brake position. Return the trigger to the neutral position.

The ESC will beep four times and the green light will come on, indicating the ESC has been set up.

BODY INSTALLATION

• Decal the body to your liking. Use the photos on the box as a reference.

MAINTENANCE

TIPS

BEFORE EACH RUN

• IMPORTANT: Check to make sure that all screws are tight. Always use threadlock (DTXR2010) on screws threading into metal.

• Check the condition of your radio system batteries and replace/recharge if necessary.

• Make sure that all of the moving parts of the Vendetta SC move freely and do not bind.

• Turn on the radio and make sure the servo moves easily and in the proper direction.

• Check for any broken or damaged parts. Replace them before running the Vendetta SC. Running the Vendetta SC with broken or damaged parts could damage additional parts.

• Install the body onto the chassis using four body clips.

AFTER EACH RUN

• Clean any debris from the chassis and moving parts.

• Check for any broken or damaged parts. Replace them

before the next run.

• Disconnect and remove the battery from the chassis.

• Allow the motor and ESC to cool.

AFTER EVERY 10 RUNS

• Make sure that the bearings are free of dirt and debris, and roll smoothly.

• Check the shocks for oil leakage. Inspect the shafts and O-rings for wear and damage. Replace if necessary. IF a shock shaft has scratches you can feel with a fingernail, it should be replaced.

• Make sure the tires are still securely glued to the rims.

• Make sure that all wires are properly connected.

• Make sure the ESC, servo and receiver are properly secured.

TUNING

GUIDE

When tuning the Vendetta SC make sure that you have equal lengths from one side to the other on the shocks, upper rods, and front pivot ball knuckles. Also, make sure to have the shock pre-load adjusters at the same setting from left to right. They do not have to be the same front to rear.

RIDE HEIGHT ADJUSTMENT

The ride height of the Vendetta SC is easily adjusted by using the clip-on pre-load collars. To increase the ride height of the Vendetta SC, add more pre-load collars between the shock cap and the upper shock collar. Make sure you have the same pre-load from side to side. To lower the ride height, remove the pre-load collars. TIP: Rough, bumpy surfaces require higher ride height; ﬂ at, smooth, or high traction surfaces allow a lower ride height.

PINIONS

The Vendetta SC comes stock with the 12 tooth pinion. To obtain higher top speeds you can install a larger pinion gear onto the motor. This will, however, decrease your acceleration and run time. TIP: Smaller pinion equals more torque, less top speed. Larger pinion equals more top speed, less torque. If you use a larger pinion, it is recommended that you either solder your motor wires directly to the ESC or use a hichcurrent motor connector.

WHEELBASE

SHOCK SPRINGS

The Vendetta SC comes stock with medium springs (yellow, DTXC8952). For low traction or bumpy tracks, use a soft spring (White, DTXC8953). For high traction or smooth tracks, use a ﬁ rm spring (Green, DTXC8954).

FRONT SHOCK ADJUSTMENT

Top Shock, Outer Position:

More Steering

Faster Suspension Reaction

Inner Mount Position:

More Slow-Speed Steering

FRONT

Top Shock, Inner Position:

Slower Steering

Smoother Over Bumps

Outer Mount Position:

More High-Speed Steering

Moving the tops of the shocks to the outer position will increase steering reaction but decrease front traction. Moving the tops of the shocks in will result in slower steering reaction but will be smoother over bumps and have more front traction. Mounting the bottom of the shocks in the inside hole will give more front traction but slower steering reaction. Mounting the bottom of the shocks in the outer position will give less front traction but increase steering reaction. The lower mounting points are for major adjustments and the top mounting points are for minor adjustments.

SPACER IN REAR

FRONT OF VEHICLE

You can adjust the wheelbase on the Vendetta SC by placing the adjuster clips in front of or behind the rear hub carrier. A shorter wheelbase will provide more steering, while a longer wheelbase will be more stable.

REAR SHOCK ADJUSTMENT

Top Shock, Outer Position:

More Steering,

Less Rear Traction

Inner Mount Position:

Less Steering,

Smoother Over Bumps

REAR

Top Shock, Inner Position:

More Rear Grip

More Rear Traction

Outer Mount Position:

More Steering,

Less Control Over Bumps

Moving the tops of the shocks out will increase steering reaction and decrease rear traction. Moving the tops of the shocks in will result in slower steering reaction but will be smoother over bumps and have more rear traction. Mounting the bottom of the shocks in the inside hole will give more rear traction. Mounting the bottom of the shocks in the outside hole will give less rear traction and increase steering reaction. The more angled the rear shock is, the more side grip. The more vertical the rear shock is, the less side grip. The lower mounting points are for major adjustments and the top mounting points are for minor adjustments.

Page 9

SHOCK OIL

The Vendetta SC comes with 30-weight oil in the shocks. The handling of the truck can be tuned by changing the shock oil to either heavier (bigger number) or lighter (smaller number). By putting heavier oil in the shocks, the truck will have less chassis roll and become more responsive. Putting lighter oil in the shocks will cause the truck to be less responsive and have more chassis roll. For smooth, high-traction surfaces, a thicker oil would be best. For low-traction or bumpy surfaces, a lighter oil would be best.

CAMBER

2˚ NEGATIVE CAMBER

ADJUST LENGTH TO CHANGE THE CAMBER

FRONT TRACK WIDTH

The Vendetta SC has adjustable front track width due to its pivot ball knuckle design. To decrease track width, screw in the upper and lower pivot balls equally. To increase track width, screw out the upper and lower pivot balls equally. Make sure that both sides are the same distance from the end of the upper and lower arms. You can check this by measuring from the end of the upper and lower arm to the outside of the knuckle. Track width affects the truck’s handling and steering response. Wider front track width decreases steering reaction and front grip. Narrow front track width increases steering reaction and front grip.

TOE-IN AND TOE-OUT

TOE-IN

Camber refers to the angle at which the tire and wheel ride in relation to the ground when viewed from the front or rear. Negative camber is when the wheels lean inward and positive camber is when the wheels lean outward. Usually adding a small amount of negative camber (0° to -2°) will increase traction. However, adding too much camber will decrease traction. The objective is to keep as much of the tire as possible in contact with the running surface. Never put in positive camber. Make sure that both sides are equal.

Use the DuraTrax Pit Tech™ Camber Gauge (DTXR1145) to accurately set up your Vendetta SC.

CASTER

The Vendetta SC has adjustable caster. Caster refers to the fore/aft angle of suspension. By placing the adjuster clips behind the front upper arm, you decrease caster angle. This will give more initial turn-in but decrease on-power steering and straight-line stability.

TOE-OUT

Toe-in is when the fronts of the tires point towards each other. Toe-out is when the fronts of the tires point away from each other. Toe-in increases stability during acceleration and high speed. However, toe-in also decreases steering when entering a corner. Toe-out will increase steering into corners, but will decrease the overall stability during acceleration. The front typically is set up with 0° to 1° of toe-in.

Placing the adjuster clips in front of the front upper arm increases the caster. This will increase on-power steering and straight-line stability, but reduce initial turn-in.
