Traxxas TRX-4 Chevrolet K10 1979 1:10 RTR Copper

Higher ground clearance

The factory-installed Long Arm Lift kit increases the ground clearance by 2.5 cm. This allowed the use of larger 2.2” wheels with Canyon Trail tires. With this equipment, the RC model will be unbeatable in the field.

Extended wheelbase

The chassis of the model has been extended to a wheelbase of 336mm to capture true scale proportions. A longer wheelbase will also provide more stability when driving.

Clipless bodywork

The new system of fixing the body with beaks in the wheel arches ensures quick and easy battery replacement, and the appearance of the body is not disturbed by the clips. Dismantling the body can only be done by pressing the beak and pulling the body upwards. Fitting the body is even easier, just put it on the chassis.

TRX-4 chassis

The TRX-4 chassis is built from two steel profiles that ensure sufficient rigidity of the chassis. Thanks to the proven location of the engine in the front part, sufficient load on the front wheels is ensured. The battery is located in the axis of the chassis, so the model is precisely balanced and does not tilt while driving. The chassis is thought through to the smallest detail, including cable routing and mounting holes for optional accessories.

Axles with axle transmission

The TRX-4 chassis uses gantry axles with an axle gearbox. The axle gearbox increases the ground clearance, reduces the stress on the differentials, transmission, cardan shafts and further reduces the torsional force - the model tilts less.

The front wheels can be turned by an angle of 45°, the steering is provided by a Traxxas 2075X servo with metal gears. Thanks to the new chassis, the model achieved a great approach angle.

Two-speed gearbox

The model is equipped with a two-speed gearbox. Gear change is controlled by the red rocker switch on the transmitter. This solution makes the TRX-4 chassis a very versatile model that can drive slowly and quickly - as you need.

Lockable differentials

The differential locks are independently controlled by 2 servos. The power from the servos is transmitted via bowdens to the differentials. The shutters are controlled by a three-position switch on the transmitter and provide the following combinations:

• 
  
• Both differentials are open
  
• Only the front differential is locked
  
• Both differentials are closed
  

GTS oil dampers

The four oil-filled GTS dampers are longer thanks to the higher ground clearance and provide even smoother damping and perfect handling. The aluminum bodies of the shock absorbers are equipped with a nut to adjust the preload of the springs. Maximum tightness of the shock absorber around the piston rod is ensured by special sealing X-rings.

Authentic wheels

Large Canyon Trail tires in extra soft S1 compound are glued to replica original chrome 2.2" wheels with eight holes and center hub cap. Wheel carrier is 12mm.

Servo steering

The control of the model is ensured by the digital servo Traxxas 2075X high-torque, with a moment of 9 kg.cm. The servo is equipped with two ball bearings on the milled shaft and metal gears for maximum durability. Waterproof* construction.

Gearbox and differential servos

The model is equipped with a total of three waterproof* micro servos 2065 with a torque of 2.5 kg.cm. Two servos independently control the front and rear differential locks. The third servo then ensures the shifting of the two-speed gearbox.

Titan 21T engine

The model is powered by a Titan 21T 550 DC motor. The motor provides smooth operation from low revs. For better cooling, a propeller is integrated in the motor, blowing air to the rotor.

DC regulator

The heart of the Traxxas model is the XL-5 HV DC electronic controller. The regulator is designed for powering a 2-cell or 3-cell LiPo battery. The model can also be powered by 6-7 cell NiMH batteries. Simple choice of driving modes and other settings, using the EZ-SET button. Indication of the status of the controller by an LED diode. LVD protection against undercharging of the LiPo battery. Thermal protection. Water-resistant* construction.

The Traxxas XL-5 HV controller supports 5 driving modes:

1. 
   
2. Sport : Drive forward, brake and reverse
   
3. Race : Drive forward and brake. Reverse is not available
   
4. Training : Forward driving limited to 50% power, braking 100% and reverse limited to 50%. this mode is suitable for children
   
5. Trail : Drive forward, brake, reverse. Handling near neutral is very subtle
   
6. Crawl : Driving forward, brake in neutral and straight back.

Lighting - constant

For a breathtaking appearance during evening trips for adventure, we recommend that the model be equipped with the original Traxxas LED lighting complete set for TRX-4 Chevrolet 1979. The lighting not only looks great, but also illuminates the road perfectly. All the LED lights of this lighting are always on. The kit can later be upgraded to Pro Scale.

Pro Scale lighting - multifunctional

By installing the Pro Scale lighting, you get all the realistic functions of a real car (functional brake and reverse lights, functional indicators and warning lights, adjustable headlight intensity). The possibility of remote lighting control using a phone via a Bluetooth module. Installing lights on a Bronco model requires a Pro Scale module, an installation kit, and a lighting kit.

Both types of lighting can be supplemented with a light roof ramp and fender lighting.

Winch

The winch is an integral part of every expedition model that will pull you out of any terrain. The original Traxxas winch is accurately, to scale, designed for TRX models. The winch is controlled by a remote control and develops a pulling force of up to 4.5 kg. To install the winch, it is necessary to add a tuning bumper - (more in the description of the item).

Transport bag

Transport the RC model comfortably and safely in the Robitronic transport bag. The bag is waterproof and has an elasticated edge that can be adjusted to the model. Thanks to the Velcro strap, the model is easy to carry. The synthetic material can be easily cleaned with water or soap suds if necessary.

Traxx tracks for every terrain

The new Traxxas crawler chassis Traxx will give your TRX-4 an extraordinary, dramatic look and you can drive it through any terrain. The easy installation of this belt tuning kit delivers a virtually unstoppable power and traction upgrade.

Accessories for normal operation

For normal operation of the Traxxas RC car, you need bolt glue, good quality tire glue, silicone shock oil and a set of screwdrivers. We recommend an affordable set of tools for cars from our range.

The thread or head of the screw is dripped with screw glue, which fixes it and the vibrations caused by driving prevent the screw joint from loosening. The screw adhesive has a special composition that allows the screw connection to be easily loosened with an adequate torque without damaging the screw head. Never use ordinary instant glue, it might be impossible to loosen a screw stuck like this!

Tire glue is used to glue the tires to the disc rim. It is always necessary that the tire is firmly stuck to the wheel rim all the way around! If the tire is not glued all the way around, it may tear. Tire glue has a special composition that is able to glue materials such as rubber or nylon, and at the same time, after hardening, the glue is flexible. Never use ordinary instant glue - it is not flexible after hardening and cracks would gradually form in the tire around the rims!

Sometimes it is necessary to add silicone oil to the dampers of the model. During normal operation, there are only slight leaks of silicone oil on the piston rods of the shock absorber. In the event that the surface of the damper pistons or the condition of the seals is in poor condition, the oil leakage may be large. For these cases, so-called repair kits are supplied. In the range of tuning parts, piston rods with an extremely hard TiN (titanium nitride) coating are delivered to all shock absorbers. Piston rods with a TiN surface are easily recognized by their golden-green color.
