DriftART4 Factory Assembled Chassis + CNC Alloy Steering Knuckle & Rear Hub

99140+98205 DriftART4 Factory Assembled Chassis + CNC Alloy Steering Knuckle & Rear Hub
We are very happy to introduce to you the new generation mini RWD drift chassis, DriftART4.
(99140 is factory assembled chassis, no motor , servo, ESC and tires)

The previous generation DA3S has been verified by a lot of competitions and has achieved good results in various events. Based on the many original designs of the previous generation, DA4 has been further evolved, improved many details, and further added a lot of original designs to give full play to its excellent performance and original design.

1. Playability:
There are a lot of optional parts to choose from. The chassis can be equipped in the direction of competition or in the direction of fun. DA4 is a drift chassis that can be matched with different driving styles.
Equipped with a large number of high-quality metal parts, rich adjustability, high assembly precision, even if it is not OP, you can enjoy an excellent and rich drift experience.

2. Compatibility:
The chassis supports both 1:28 and 1:24 scale bodies when open the box.
Without purchasing additional parts, it can support very narrow car bodies, such as 1:28 AE86, and can install car tongue and L mount parts.
Both the front and rear swing arms can be extended, and with the factory-provided long ball cups, they can be matched with a wider 1:24 car body.
By purchasing extensions, extremely wide car bodies can be supported.

3. Ease of use.
Compared with the previous generation of DriftART chassis, the difficulty of assembly is further reduced, and the installation is more reliable and stable.
Two versions are available: 1 Factory assembed version: no assembly is required after receiving it, only the electronic equipments and wheels and chassis need to be installed;
2, Kit version, the parts are packaged according to the installation steps, and the user installs the car according to the order of the parts package, which is easy and clear!

Product features:
Equipped with dual rate suspension:
- The suspension system is composed of CNC-made aluminum alloy and stainless steel, and gold-plated brass parts.
- Two sections of springs with different coefficients can be combined to produce various degrees of softness and hardness.
- Increase the operating travel of the suspension, provide dual-stage support strength, absorb more vibration and stabilize the chassis.
- The shock absorber position can be adjusted steplessly, and the adjustment is quick and easy.
- Equipped with anti-slip rubber rings, it will not loosen with vibration.
- Comes with 5 sets of springs, and 7 sets of additional springs are available. (Need to be purchased separately, number 97402)

Equipped with 3D steering system:
-1, equipped with an adapter ring, not only suitable for metal servos, but also for plastic servos.
-2, Adopts V-track bite, and the two sides are completely symmetrical after installation.
-3, The locking angle of the screws is optimized, and the screws are anti-loosening and can be easily installed to the middle angle.
-4, The appearance is more coordinated, more natural, and more imposing.
(DVF (Dual Vactor Foil) This is the core feature of DriftART's original creation, which makes the front steering geometry remain harmonious and consistent in the case of large Camber and large Caster. It is reflected in the operation of the shock absorber, and the caster angle and toe angle are more stable.)

Equipped with the Offset Master front wheel axle:
-1, The offset of the wheel cup is adjustable, not picky about the wheel hub, and can adapt to any degree of wheel hub.
-2, While maintaining a large steering angle, it can achieve low offset. The trade-off between steering angle and offset.
-4, steering cup optimized geometry, Ackerman angle is more balanced.
(The wheels of micro cars have different "degrees", that is, offset, offset value.
In the early 1/28 system, players can only adjust the width of the car by replacing wheels of different degrees. Players need to repeatedly purchase wheels of different degrees.
Most new-era mosquito cars can adjust the length of the swing arm. Even so, there are still many restrictions. For example, the pursuit of low offset frames cannot use low-degree wheels. And the pursuit of large steering cars, the offset is too large, the wheels rub against the car body and there is a phenomenon of wheel shrinkage.
The new offset master of Wushuang 3S, the degree of [wheel cup] is adjustable (offset is adjustable), which not only adapts to any degree of wheel, but also can reduce the offset and maintain the simulation characteristics of the wheel.)

Equipped with DriftART telescopic dog bone (stainless steel)
-The dog bone is made of stainless steel CNC, which is highly wear-resistant, smooth, strong and anti-fracture.
-The telescopic dog bone can be stepless extended by 3m. With the additional extension piece, item No. 97513, it can be extended by 6mm.
-The brass pin with a thickened 2mm diameter can be replaced. The straight shaft uses 7075 aluminum alloy. The brass pin is self-lubricating and softer than 7075. If it is worn, the pin can be quickly replaced.

Equipped with 7075 aluminum alloy rear straight shaft
-The rear straight shaft uses 7075 aluminum alloy, which is wear-resistant and durable.
-The mortise and tenon structure, stable and accurate installation, high concentricity.
-Adopts hollow and lightweight design.
(In the past, in order to adapt to different car widths, players could only adjust the degree of the rear wheel hub, so they needed to buy a lot of wheels with different degrees. Now, the length of the rear swing arm of most frames is not adjustable. DA4 provides a high-quality solution.)

Equipped with a full toothed belt drive
-Aluminum alloy expandable drive shaft, high concentricity, equipped with a toothed belt, enhanced explosive power.
-Silent, quiet operation, playing at home can minimize interference to others.
-The new geared motor gear can be installed with a follow-up cooling fan to achieve the effect of active cooling. (Fan optional parts need to be purchased separately)

Equipped with a Wheelbase Master full metal chassis
- Aluminum alloy base plate made by CNC.
- The wheelbase is steplessly adjustable from 90-123mm, suitable for most 1/28-1/24 car shells.
- The wheelbase and servo position can be accurately displayed.
- The lightweight and narrow body design makes the body more concise and slender, and with the reinforced rib structure, it provides excellent rigid support.
- Strengthen the support at the rear of the chassis to make the installation of the gearbox easier and more stable.

It has a rich frame layout and structural changes.
-1, tie rod installation method, bringing a rich experience:
T-type high-mounted (wide/narrow array), T-type inverted (wide/narrow array), V-type (wide/narrow array).
The triangle is V-shaped, easy to install and higher strength. T-type, small offset, easy to adjust parameters.
-2. The battery rack has modular characteristics and can adapt to batteries of various sizes. It can carry out a rich structural layout. Through the battery layout, the center of gravity of the frame can be changed. The DA4 battery rack is not only light, but also very easy to use!
-3. The motor layout is changeable, and the motor layout can achieve a total of 120 degrees of infinite angle adjustment.
-4. The gearbox can be flipped, the motor layout position is doubled, and the change of 120 degrees x2 = 240 degrees can also achieve rear motor or rear battery.

Equipped with Aluminum Alloy Rear Toe Master,the rear swing arm seat
- CNC-made aluminum alloy rear swing arm seat.
-Combined into an integrated swing arm system, adjusting the toe angle will not affect the inclination angle, which is convenient for quick adjustment and easy to disassemble and install.
-The rear toe angle can be infinitely adjusted from 0 to 4°, and no accessories need to be removed, which can be adjusted quickly.

car kit
- CNC-made motor mount.
-Can support full-angle motor installation positions up to 180 degrees.
-High strength will not bend, and fast heat conduction is conducive to motor heat dissipation.
-You can install the expansion equipment board, install the ESC near the motor, move the center of gravity further back, and enhance the combat effectiveness.
