THE BOTTOM LINE
Kyosho’s Inferno GT delivers great performance and handling. It’s rock-solid and runs well enough to keep most of us entertained for hours.

Most of us will never get behind the wheel of a full-scale supercar; we can only imagine what it’s like. But thanks to Kyosho, we can drive the ever popular Ferrari F430 GT—but as an 1/8-scale nitro Inferno GT RTR! Hey; I’ll take what I can get!

WHAT YOU NEED TO KNOW


The Ferrari comes as a complete RTR package. The radio system is installed and the body painted and detailed, and accessories such as a fuel bottle and a cool dual-C battery glow igniter are in the box.
The Kyosho Inferno GT comes ready to run with its radio gear installed and a .28 nitro engine. All that you need to get are nitro fuel and 12 AA batteries.

The chassis layout and drivetrain are very similar to an 1/8-scale buggy’s, and the car is, in fact based on the world-renowned 1/8-scale Inferno buggy.

The very durable drivetrain transfers power to bevel-gear differentials that can be tuned by using oils of various weights (viscosities); there are strong steel dogbone axles and all-metal gears.

The Inferno GT comes with a powerful .28 engine that’s used in other Kyosho RTR vehicles. It’s fast and has well-proven performance and reliability.

The Inferno’s 2-speed transmission offers neck-breaking acceleration in first gear and jet-like speeds in second. The shift point is spot on, and that keeps the engine right where it needs to be in the powerband.

The suspension is a critical, and this car has almost every adjustment you could want, so you can match it to your driving style no matter where you drive it.

PERFORMANCE


A rigid, 3mm aluminum chassis provides consistent handling. Kyosho’s trademark blue anodizing and fully countersunk screw holes complete the Ferrari’s foundation.
I took the Inferno GT to an empty parking lot. After only a few tugs on the pull-starter, the engine fired up and began to idle. I let it come up to temperature and then took a few seconds to set the needles.

First, I made high-speed, straight-line passes to get used to the handling and speed; that detailed Ferrari F430 GT body looked great tearing across the parking lot. Second, I took a moment to appreciate just how fast it went.

NEEDED TO COMPLETE
• Nitro fuel
• 12 AA batteries for radio

WHAT WE USED
• Sidewinder 30%


The Inferno GT accelerates off the line and tears away with a quick shift into second gear. At speed, it seems to have an on-power push. The car’s speed makes the front tires fight for traction—not all that bad because it makes the car stable and easy to control. It’s so over-powered that you can break the tires loose just by stabbing the throttle. At lower speeds, it turns well and holds a tight line. Be warned: if you grab too much throttle during a corner exit, the rear will break loose and send the car into a slide. The 4WD prevents it from spinning out completely; a slight countersteer will allow you to drift through corners with surprising accuracy. The car feels as you might expect the full-size Ferrari to feel: tight handling and all the power anyone could want.


The Inferno GT is based on the Inferno buggy platform that has been refined throughout its illustrious 20-year racing career.

After running many laps around my makeshift racecourse, I noticed that the incredible stopping power had started to fade and the car took longer to come to a stop. I figured that something had come loose, but there was nothing wrong with the car itself. It seems that the single rotor does a great stopping job but can heat up when used and cause the brakes to fade. I had used the brakes much more than I would during regular driving, but I’d try doubling up on the brake discs to help dissipate the heat and keep braking strong during long runs.

Overall, the car handled really well and performed as I hoped it would.

 

THE SPECIFICS
CHASSIS

LENGTH: 18.9 in. (???mm)
WIDTH: 12.2 in. (??? mm)
WHEELBASE: 12.8 in. (???mm)
TYPE: Stamped plate
WEIGHT: Approx. 7 lb. 4oz.
MATERIAL: 3mm aluminum
WEIGHT: Approx. 7 lb. 4oz.
SPECIAL FEATURES: The rigid, 3mm-thick aluminum chassis is blue anodized and has countersunk screw holes

The chassis resembles that of a standard 1/8 buggy, so it will be very durable and will last the life of the vehicle.

SUSPENSION
TYPE: 4-wheel independent
SHOCKS: Plastic-body, oil-filled, coil-overs
WHEELS: 5-spoke wheels with 17mm hex
TIRES: Replica racing tread
MATERIAL: Molded plastic composite

The suspension is almost the same as the Inferno off-road buggy’s, but with a few minor tweaks. This means that the car is surefooted and ultra-adjustable.
DRIVETRAIN

TYPE All-wheel drive
DIFFERENTIALS (F/R) Sealed bevel-gear
TRANSMISSION 2-speed auto shifting
DIFFERENTIALS (F/R) Sealed bevel-gear
BEARINGS Metal-shielded ball bearings
BRAKES Steel discs with fiber pads
DRIVESHAFTS Steel dogbone axles

The driveline is not exactly innovative, but it is very efficient and durable. The 2-speed works flawlessly and suits the car well.

POWER PACKAGE
TYPE Kyosho .28 engine
CARB Slide-valve with high- and low-speed needle adjustments
EXHAUST Aluminum tuned pipe with
aluminum-tube header
CLUTCH 3-shoe, aluminum flywheel

The included .28 is very reliable and held its tune well. After break-in, I set the needles and ran all day without making another adjustment. Its power output is worthy of the car’s Ferrari body.


A massive foam-rubber front bumper protects the front end during collisions and provides a soft cushion for the front of the Ferrari shell.

Suspension bred to withstand grueling hour-long off-road events finds a home under the Ferrari body. The rugged, efficient drivetrain comprises durable steel dogbones and full ball bearings.

Rugged steel tie rods join the cast-aluminum steering knuckles to the aluminum steering plate. Steering Ackerman can be varied to increase or reduce response.

Kyosho’s GXR-28 engine is mated to an aluminum, tuned exhaust system that has a two-piece pipe. A patented Cam-Loc pull-start mechanism eliminates the parasitic drag that would usually affect the engine’s overall output.

The Inferno GT is based on the Inferno buggy platform that has been refined throughout its illustrious 20-year racing career.

High-traction rubber tires (93x41mm) have realistic treads and foam inserts for support, and they’re mounted on gray plastic 5-spoke wheels.

High-volume, composite, oil dampers smooth out the ride and keep the Ferrari’s chassis flat during all-out cornering. Threaded collars set the spring tension and the car’s ride height.

THE LAST WORD

The Inferno GT is a performer. Whether you’re a newbie or an experienced driver, you’ll enjoy driving it. It has the performance and handling that might keep your desire to own the real thing in check—well, at least until you earn your first million.
