Traxxas 4-Tec 2.0 1:10 BL-2s RTR

4-Tec 2.0 chassis

The chassis of the Traxxas 4-Tec 2.0 is made up of a three-dimensional composite molding (nylon filled with glass fibers) that is light and stiff at the same time. Everything was subordinated to obtain the lowest possible center of gravity position. The axle drive is no longer solved by problematic belts, but by means of a central shaft - similar to the Slash 4x4 models.

To simplify maintenance, the chassis is of modular construction. The front, center and back of the model can easily be separated.

4x4 drive

The excellent driving characteristics of the model are made possible by the all-wheel drive. The torque is transmitted from the engine through the central drive shaft, differentials and half-axles to the wheels. All shafts are mounted in bearings for maximum efficiency.

Oil dampers

The 4-Tec 2.0 chassis effectively overcomes bumps with oil shock absorbers with exclusive X-rings that seal perfectly. The shock absorbers are adjustable - the preload of the springs can be changed using washers, you can adjust the stiffness by changing the viscosity of the oil in the shock absorber.

Adjustable body mounts

Traxxas remembered that each body has specific shapes and therefore different places for optimal mounting. That's why adjustable body mounts are used on the Traxxas 4-Tec 2.0 chassis, so you can fix your body in the most convenient place.

The placement of on-road bodies, for example from Killerbody, will not be a problem!

The possibility of increasing the turning angle of the front wheels, limiting the vertical movement of the arms

Traxxas remembered those who like to drift. For drifting, it is important that the turning range of the front wheels is as large as possible. That is why the suspension of the front wheels of the 4-Tec 2.0 chassis is designed in such a way that you can increase the turning angle with a simple adjustment.

Furthermore, the suspension includes limitable vertical movement of the arms. Using the M4 set screw, you can limit the vertical movement of the arm. This allows you to go through corners faster and improves handling when drifting.

Easy battery replacement

You use NiMH batteries with a height of 23 mm and LiPo batteries with a height of 25 mm. For TRX chassis - no problem. A simple rotation of the holder ensures a firm fixation of the battery with a height of 23 mm and 25 mm. In addition, the battery holder is not fastened with a clip, but with a plastic clip from the side, which is significantly easier and faster.

Tight tooth clearance

Precise adjustment of the gap between the teeth is now a piece of cake. The motor bed includes mounting holes for precise adjustment.

Front and rear differential

Ideal power distribution is ensured by front and rear differentials. The clutch of the differential can be changed by changing the oil with a different viscosity (thicker or thinner).

Model wheels with disc brakes

The model's authenticity is enhanced by the detailed brakes, which include imitation discs with calipers. The 5-spoke wheels, with 12 mm lugs, are shod with on-road high-grip tires.

Servo steering

Digital Traxxas servo 2075 high-torque waterproof with DC motor and nylon gears has a torque of 9.0 kg.cm and a speed of 0.17 s/60°@ 6.0 V. For water resistance*, the servo box and the output 1000 edges are fitted with seals. Two ball bearings provide very smooth operation.

TQ receiver

The Traxxas TQ 2.4 GHz three-channel receiver ensures safe driving without interruptions. Easy pairing with one button. Status indication by LED diode.

Traxxas TQ RC Kit

The model is controlled by a two-channel proportional steering wheel RC radio Traxxas TQ, working in the 2.4 GHz band - operation without interference. The transmitter is powered by only 4 AA cells.

There is a rotary knob on the transmitter that trims the steering (so that the model goes straight if the steering wheel is in the center position). The status of the batteries in the transmitter is indicated by an LED. Reverse can be set on the transmitter on the throttle and steering channels.

Recommended LiPo batteries:

With modern LiPo batteries, the model will have maximum acceleration. The model can be operated on a 2-cell (7.4 V) LiPo battery.

Work mat 91x51cm, for service of RC models and other modeling work. Prevents damage to the workbench, resistant to chemicals. Practical compartments for organizing parts and tools.

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. So-called repair kits are supplied for these cases. 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.
