Kyosho – Inferno ST-RR – More Detail


Kyosho Japan have more detail on their new Inferno ST-RR

Translation :

The fact that further strength is given to Inferno ST-R where DNA of the champion of the world machine breathes, is, “Inferno ST-RR”. Running the whole distance power of the stadium track/truck and racing efficiency of the buggy were made to unite in “[toragi]” race, the efficiency which can aim for apex was learned. It does long wheel based conversion and the standard equipment etc of the big bore damper at ST-R ratio, furthermore brushing up the various parts. Not only simply fast, efficiency and the preeminent durability which can maintain the speed over long haul are actualized. That the running the whole distance power which is superior not only the circuit, even with the familiar rough road capability showing. The uncultivated land the happiness of which runs dynamically and comes out is extraordinary. Please enjoy the highest [toragi] efficiency by all means.


The main chassis which the wheel base to 25mm long is converted adopting the long torque rod at ST-R ratio. To optimize also balance station, preeminent handling efficiency.

The shock absorptivity which is stabilized under severe condition and the big bore damper which maintains attenuation power. It contributes to also the quantization of setting. Protecting the sliding section with the bellows type dust boots.


Approximately adopting the lightweight universal swing shaft for 6 left and right and center front and back. Approximately just with light weight conversion of ST-R ratio 28g. Actualizing high maneuverability.


Holding down total height, it decreases the front reflecting surface substantially, designing the low height body which decreases aerodynamic drag. Generating powerful down fourth in the aerodynamic design which is superior.


The long wing stay which promises a more certain down fourth to around the rear axle. Coupled with the private body, showing the preeminent aerodynamic effect.


The wide wheel hub and secure tire fixing and the maintenance characteristic which tread 18mm are expanded adopting the nylon resin one somatotype wheel nut which is compatible at ST-R ratio.

  • The shaft drive 4WD machine which designates [inhuano] MP777 as the parent.
  • Light weight conversion high rigidity, actualizing high intensity with complicated milling and hard alumite processing.
  • The final gear & the diff. pinion gear of spiral gear adoption to modify the material, durability furthermore improvement.
  • It starts shaving, the suspension plate & the steering wheel plate.
  • Polycarbonate make clear body.

Kit Include :

  • 2ch2 servo for [puropo]/each company car
  • Rear exhaust 21~28 class for engine/each company car (P type)
  • Manifold [chiyundomahura]
  • Tire & inner sponge
  • Fuel, starting equipment
  • Paint for body paint
  • [puropo] designated electric battery
  • No96176 HG oil
