Arrma Firearm 6S BLX 1: 7 4WD RTR white

Hand brake

The specialty of this model is the handbrake, which is remotely controlled via a transmitter. The parking brake module includes an S650 servo and a disc brake that brakes the rear axle like a real car. This way you can learn to go through curves like a true professional.

SPEKTRUM® S652 digital servo

• Servo SPEKTRUM® S652 with metal gears

• Torque 19.08 kg-cm at 7.4 V.
• 32% higher torque and 5% faster than the ADS-15M servo

AC regulator SPEKTRUM ™ COMPANY ™ 150A SMART 3S-6S

The model is controlled by a modern SPEKTRUM-COMPANY-150A SMART controller with a 32-bit ARM Cortex M4 microcontroller, which is able to read complete telemetry and transmit it to the receiver using an integrated wire in the new IC5 connector. Data is transmitted via the SRXL2 protocol. The controller reads information about the type, temperature and voltage of the battery cells directly from the Smart battery. Current, temperature, total battery voltage, battery cell voltage, battery temperature, remaining capacity and motor speed are available in real time.

The electronics are completely encapsulated in a special potting compound, which prevents the entry of moisture * or dirt into the electronics. The controller is switched on and set with the buttons under the rubber cover.

The steering wheel is covered with a foam rim for a firm grip. The layout of the controls is practical and intuitive - all controls are positioned so that they are quickly accessible when needed. A secure loop is available for fastening to the strap.

• 3-channel steering wheel RC set Spektrum SLT for reliable control
• Proven design for comfortable grip without fatigue
• Possibilities of limiting the maximum deviations of the control channel and gas
• Double steering channel deflections and 50%, 75% and 100% engine power limiter
• You can use the third channel for additional devices, e.g. ro sound modules.

SMART Spectrum Technology

Spektrum Smart technology offers more information about the model, telemetry transmission, easier operation and battery care. All SMART components, including batteries, are able to communicate and transmit telemetry. To display complete telemetry, it is necessary to have a compatible Spektrum transmitter with a display. The telemetry display depends on the radio type of the specific model.

You can find more information about Smart technology in our blog . An overview of compatible transmitters here.

Recommended batteries

It is best to use one LiPo drive battery with 4 or 6 cells (14.8, 22.2 V). In this case, you short-circuit the second input of the Y-cable with the enclosed jumper IC5, which is already part of the RC car package.

It is also possible to operate the model on a pair of two-cell (7.4 V) or three-cell (11.1 V) LiPo batteries connected in series. In this case, connect both batteries to the Y-cable with which the controller is fitted at the factory. The disadvantage of this solution is that both batteries must be completely identical and equally charged. Therefore, it is better to use one 4 or 6 cell battery, see above.

• For normal riding LiPo battery Spectrum 14.8 V 5000 mAh with Smart technology or Spectrum G2 14.8 V 5000 mAh with Smart G2 technology. Thanks to its lower speed, this solution is suitable for children.
• For normal riding with a longer operating time LiPo battery Black Magic 14.8 V 6500 mAh. Due to the limited speed, this solution is suitable for children.
• For the maximum possible speed, we recommend one Black Magic 22.2 V 4200 mAh battery
• For the maximum possible speed, we recommend a pair of three-cell batteries Spektrum 11.1 V 5000 mAh with Smart technology, or Spektrum G2 11.1 V 5000 mAh with Smart G2 technology.

Spektrum batteries with Smart technology are currently the most modern and safest way to maintain and charge batteries. You can find the advantages of Spektrum Smart technology here.

Smart G2 batteries are even simpler and safer, thanks to the absence of a balance connector. In addition, G2 batteries have up to 3x faster automatic discharge into storage mode. Smart G2 batteries can only be charged on Spektrum Smart and Smart G2 chargers.

Recommended chargers for conventional and Smart batteries

Spektrum Smart chargers can charge both Smart and Smart G2 batteries as well as conventional batteries. Previously sold Smart chargers, after the upgrade, also support Smart G2.

• Mains charger Spektrum Smart S1100 with one output 1x 100W.
• Mains charger Spektrum Smart S2100 with two outputs 2x 100W.

To connect the battery to the above-mentioned chargers, you need an IC5 / IC3 charging adapter.

• High-performance mains charger Spektrum Smart G2 charger S1400 1x400W AC with one 400W output.
• High-performance mains charger Spektrum Smart G2 charger S2200 2x200W AC with two 2x200W outputs.

Accessories for normal operation

For normal RC car operation, you need tire glue, bolt glue, a tool kit and silicone shock absorber oil. From our range we recommend an affordable set of tools for RC cars.

The tire glue adheres the tires to the rim of the disc. It is always necessary that the tire is firmly glued to the wheel rim around the entire circumference! If the tire is not stuck around the entire circumference, it may rupture. The tire adhesive has a special composition that is able to bond materials such as rubber or nylon, and at the same time the adhesive is flexible after hardening. We recommend Robitronic Tire Glue from our offer - see recommended accessories.

Sometimes it is necessary to add silicone oil to the model's shock absorbers and change the oil in the differentials. During normal operation, there is only a slight leakage of silicone oil along the shock absorber piston rods. If the damper piston rod surface or seal condition is in poor condition, the oil leak 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.

Screw glue is required for routine maintenance. Screws screwed into the metal material (eg screws in the motor, set screw in the pinion) must be secured against loosening with this adhesive.

Protective covers for batteries

Protective covers are designed to reduce the risk associated with transporting and charging batteries. LiPo batteries can, while maintaining small dimensions and low weight, provide high discharge currents and have a large capacity for long travel times. On the contrary, the LiPo battery is particularly susceptible to mechanical damage.
