Characteristics

The unique Arrma Limitless 1:7 4WD Speed Machine Roller is optimized for 8S LiPol performance. Now you can own an RC super car that beats F1 in the quarter mile in 8.6 seconds! Choose your own drive unit with electronics and battery and beat the speed limit.

The new King of Speed Bashers!

Adapted from the original LIMITLESS™ 1:7 All-Road Speed ??Bash Roller, this new evolution of the LIMITLESS Speed Machine Roller RC car has been "designed to be even FASTER " so you can reach higher speeds than ever before! ARRMA® engineers have improved the already proven LIMITLESS platform to accommodate a larger motor and a larger controller - then just add the electronics of your choice to create your RC super car. The LIMITLESS 1:7 Speed Machine Rollerr is at the very top of the ARRMA Speed ??Bash RC car development line. He's the new King of Speed Bashers!

In a real head-to-head battle on a quarter-mile track, with the real championship winner Red Bull Racing RB7, the LIMITLESS 1:7 Speed Machine Roller RC model car won, reaching speeds of up to 240km/h and covering 400m in just 8.6 seconds !

New features of the LIMITLESS platform include a 3mm anodized aluminum chassis plate that allows the motor mount to be positioned to accommodate longer motors. An easy-to-access sliding motor mount can be used for larger diameter motors with an optional motor mounting plate, while the electronics module accommodates a larger regulator and includes a waterproof receiver box.

Important improvements have been made to increase stability and precise handling at high speeds. Also aimed at reducing drivetrain vibration, a shorter rear center drive shaft and an equally long center drive shaft. GP5 gears with a lower gear ratio reduce vibration of the central drive train. Stiffer front springs and sway bar improve handling at high speeds, and a wider rear track increases stability.

The large diameter oil-filled black anodized shocks are carried over from the original LIMITLESS, keeping the dBoots® Hoons™ all-road tires firmly planted for maximum road and oval traction. The low-drag body comes unpainted, ready for you to customize with your own unique paint job. A window mask and decals are included. Trim lines on the front and rear fenders make it easy to tune downforce and drag.

You too can enjoy the maximum experience of driving a high-speed RC car model. Install the electronics of your choice, paint the body in your signature colors and create your very own super speed RC car ARRMA LIMITLESS 1:7 Speed Machine Roller!

ARRMA® "Rattle Can Roller" Body

The low drag body comes clear so you can paint it to your liking. Includes window mask and decals. Pads on the front and rear spoiler make it easy to tune downforce and drag.

Chassis for larger motors and controllers

The variability of the arrangement on the aluminum chassis allows the use of a longer motor and a larger regulator. Gear parts are optimized for high speed when powered by 8S LiPol batteries.

Stability at high speeds

To increase stability and precise control at high speeds, changes were made to reduce drivetrain vibration, shorter rear center drive shafts and the same length center drive shafts were chosen. GP5 gears with a lower gear ratio also reduce vibration of the central drive train.

dBoots® Hoons™ speed rims and tires

The dBoots Hoons tires are firmly mounted on Speed speed discs with extra durable hubs, for maximum performance, stability and traction. Large-bore oil-filled shocks on black anodized front and rear shocks keep the dBoots® Hoons™ all-road tires planted firmly on the trail for maximum traction.

Easy engine mounting

You need to install an engine to drive the car. The motor bed is easily accessible and you can therefore quickly complete the installation, to adjust the gap between the teeth, just loosen the screws and move the motor in the aluminum rail.

How about the differential?

You don't have to disassemble the differentials laboriously and for a long time, just loosen a few screws and the differential is available in your hand.

Easy access, simple maintenance

You remove only 5 screws and you have the differential on the table ready for service.

Rear spoiler

The adjustable aerodynamic downforce rear wing and extra large spoiler in addition to the diffuser ensure maximum stability at all speeds.

Accessories for normal operation

For the normal operation of the RC car, you need tire glue, screw glue, a tool kit and silicone shock oil. We recommend an affordable tool kit for RC cars from our range.

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. We recommend Robitronic Tire Glue from our offer - see recommended accessories.

Sometimes it is necessary to add silicone oil to the shock absorbers of the model and change the oil in the differentials. 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. Repair kits or individual parts are supplied for these cases. From our range of silicone oils, we recommend TLR (Team Losi Racing) silicone oils, see recommended accessories.

For routine maintenance, screw glue is needed. Screws screwed into the metal material (e.g. screws in the motor, set screw in the pinion) must be secured against loosening with this glue.

Protective covers for accumulators

Protective packaging is intended to limit the risk associated with the transport and charging of accumulators. LiPo accumulators, while maintaining small dimensions and low weight, can provide high discharge currents and have a large capacity for a long driving time. Conversely, the LiPo battery is especially susceptible to mechanical damage.
