ARC’s all-new A11 1/10th scale Electric Touring Car is coming.

The design of the all-new ARC A11 1/10 electric touring car focuses on the following main themes: a simple design that makes setup and maintenance easier, a lower and more concentrated center of gravity that optimizes handling and performance, and lightweight components that maintain the necessary strength. With these key elements in mind, the A11 was born.

The all-new carbon fiber lower arms are available in two materials: a standard stiffness version included with the vehicle, and a stiffer version for high-grip or challenging tracks. The A11 lower arm shape ensures even stress distribution and effectively transfers the car’s weight to the tires, maximizing overall mechanical grip.

The new lower arm ball joint uses an O-ring for fixing, which makes assembly and maintenance easier. All 4.9mm ball heads are made of titanium to ensure maximum strength and optimal lightweight.

The A11 X-Low 2 shock absorber is 1mm shorter than its predecessor, the A10-25 X-Low shock absorber, and its overall mounting height is reduced by 3mm. Therefore, the A11 can only use 17mm springs. The black body of the X-Low 2 features a hardened coating, and an X-ring is used at the bottom of the oil seal to ensure smooth and good operation.

Both the front and rear shock absorbers on the A11 have been moved away from the extremities of the car to a more centralized location. This reduces moment of inertia to deliver a better handling car with superior corner-speed.

The new motor mount has bearings at the front, rear, and middle to adjust the belt tension, making the entire transmission system smoother. Another new feature is that the motor height can be adjusted using the third slot. When the top screw slot is used, the motor height is raised by 0.5mm, which can prevent the motor from scrubbing against the track in certain cases.

The A11’s new transmission shafts all use smaller bearings instead of the previous C-caps, and both the front spool and the rear differential cup are made of S2 high-hardness steel, ensuring the highest level of smoothness and durability.

Like the A10, the front and rear shock absorber brackets have two screws to adjust the stiffness. When fully locked in the default position, the shock absorber brackets are at their stiffest, providing the most direct response.

The A11’s all-new drive-train uses a completely new gear ratio: 40T for both the front spool and the rear differential, 21T for the lay-shaft pulley resulting in a final drive ratio of 1.904. The larger pulleys result in lower belt curvature and smoother transmission.

Compared to the A10, the new A11’s motor position has been moved towards the center-line of the car by 2mm to further centralize the weight of the motor.

The all-new front spool and rear differential have adopted a smaller 6×10 bearing and undergone comprehensive weight reduction. The rear differential also features a new bevel gear and design, using 5×8 small bearings internally to achieve optimal smoothness. Compared to aluminum alloy differential bodies, the all-plastic body is not only lighter but also prevents overheating, maintaining consistent performance throughout a 5-minute run.

The A11 anti-roll bars are positioned significantly lower on the chassis compared to the A10, further lowering the overall center of gravity. The anti-roll bars pass under the lower arm and connects to the outermost part, allowing them to operate precisely.

The A11 uprights are made of 7075-T6 aluminum alloy, which is high-strength and precise. The front and rear wheel hubs are identical for easy spare parts preparation.
The new design allows the front to maintain a fixed angle when aligned with the drive shaft. The rear drive shaft is also made of 7075-T6 aluminum alloy, which is lightweight and high-strength.

The new steering plate distance has been changed from 8.5mm to 8.0mm. This subtle change makes the A11’s steering more responsive, especially in tight spaces, allowing for faster lap times. The new steering plate limits the maximum steering angle to 26 degrees, ensuring a suitable angle for various grip conditions.

The new battery mount makes adjusting the battery tightness easier. Battery tightness plays an important role in the handling of the touring car. The appropriate position can be set with just a few screws and shims in the battery mount. The all-plastic battery mount further reduces the weight on the right side of the car to facilitate the use of large-capacity lipo batteries.

The A11’s design integrates the latest up stop limit function on the bulkhead. This function can adjust the body roll and lateral grip by limiting the upper travel of the suspension arms. On tracks with high grip, reducing the front upper travel can increase front-end response and prevent over-steer. Reducing the rear upper travel can reduce rear grip and increase the response when switching sides. This is an optional accessory and can be purchased separately.
