ARC A10 competition EP touring car
The A10 is ARC’s latest generation 1/10 electric touring car and it’s ready to hit the track. Built on a completely new platform, the A10 was developed with some key goals in mind – a lower centre of gravity, increased mechanical grip, easy maintenance & setup and full adjustability. The car features a new one-piece upper deck, helping the A10 to be super easy to drive out-of-the-box and suiting a wide range of track conditions. An optional two-piece design is available to independently tune the front and rear flex for racers looking to get the most out of their A10. The new one-piece motor bulkhead caters for both upper deck designs, allowing different flex options via both the chassis and top decks. The bottom of the motor bulkhead now also features a 3mm centre alignment pin to better locate the chassis when less chassis screws are used. This allows extra chassis flex to be dialled in with less likelihood of tweaking. The brand-new lower arms of the A10 are made from 3mm thick, high-quality carbon fibre plate and are stronger and lighter than traditional composite arms. The design of the new lower arms allows the arms to be moved further inboard for an even longer arm than the R12. Back-to-back testing has confirmed this new design to be even easier to drive while achieving greater corner speed.
The upper arms are now fully adjustable on the A10. This means both camber and caster are fully adjustable. This means that dive and squat settings on the lower arms can now be set without interfering with caster settings – something that was not possible on the R12. The upper arm now also incorporates mounting points for adjustable body stops. This allows the simple of use of a screw to act as a body stop. Using this allows the height of the body to be lowered while preventing the front tires from touching the wheel arches during cornering. All ball joints on the A10 are now using ARC’s low friction ball ends. These provide smoother operation with less wear and slop between the ball joints and balls.
The A10’s rear suspension system now features an integrated Active Toe System (ATS). This system allows the rear toe angle to vary during suspension travel, for further ease of tuning. By varying the angle of the ATS linkage, the amount of rear tow gain or loss can be varied to suit your driving style and track conditions. The optional horizontal body post helps to lower the rear centre gravity, while the extended rear body tower can also reduce the body deflection bend during impact. ARC’s bespoke caster gauge is included with every A10 kit. The caster gauge can be adjusted to suit most setup stations that are available on the market today.
The spur adaptor on the A10 is mounted on one side of the motor bulkhead, allowing easy access to the spur and belts. This allows for simple maintenance and spur replacement without removing upper deck and motor bulkhead. The included carbon fibre battery holder suits both standard and shorty LiPo batteries, with two corresponding sets of holes on the chassis for both types of batteries. Racers can either fasten the battery with tape or use the included adjustable battery retaining tab. The R12 SRS servo is also compatible on the new A10. Featuring a super high response speed, the SRS servo features direct chassis mounting. This brings the servo 8mm closer to centre of the chassis compared to using other low profile servos.
