Following 2-years of on-track development, Infinity has finalised their first 1:10 200mm nitro on-road kit – the IF15. Extensively tested by the 1:8 Onroad World Champion’s team drivers, the new kit has already shown winning form. In the 2018 Euro Nitro Series, Jilles Groskamp took the car to victory at the opening round and secured the TQ at Round 2. The concept for the design of the IF15 was to have the lowest possible centre of gravity and, like its big brother the IF18, create a car that facilitates easy maintenance. As a result of its low centre of gravity, the IF15 provides excellent steering feeling. The easy access bulkheads make exchanging of differentials and belts easy and reduces the time needed to find the best set-up. This is a feature of the car that is particularly beneficial when time is limited. The kit comes supplied with suspension bushes with various roll centre positions, and three kinds of front & four kinds of rear anti-roll bars meaning the IF15 can easily be tuned to any track.
The 3mm-thick 7075 duralumin main chassis boasts great rigidity and flexibility in perfect balance. Steering characteristics can be adjusted by changing the position of the chassis weight (option part). You can adjust the rigidity of the rear suspension arm by attaching the carbon plate (option part).
2-speed transmission contains highly-efficient 0.8 module gear. The newly-designed clutch is included. The clutch bell coated with special materials is durable and offers perfect clutch-meet.
Rear suspension geometry designed to provide excellent mechanical grip. Maintenance is easy and replacing the rear differential and rear belt can be done quickly. Four kinds of rear anti-roll bars are included in the kit as standard.
The rear body mount securely takes the body shell’s downforce and provides support when refuelling. The rear differential comes with a Kevlar-contained resin case and metal bevel gear. They contribute to smooth and stable operation and great traction.
The big aero front bumper has guidelines so that you can easily cut it according to the body shell to be used. This part provides extra stability to the front of the body shell and will improve consistency. The bumper also offers a position for a screw-in weight (option part) allowing you to adjust the steering characteristics quickly and easily.
The front differential comes with a Kevlar-contained resin case and resin bevel gears. The lightweight differential unit reduces understeering. Three kinds of front anti-roll bars are included in the kit as standard. The carbon bumper upper plate (option part) increases rigidity of the bumper and the body post and adjust the steering characteristics.
The steering and throttle positions are specifically designed for the low-profile-type servo to make the radio plate as low as possible, which allows for a low centre of gravity.
The front upper suspension mount is made from high-precision and rigid machined aluminium. The front drive train uses Kevlar-contained resin pulleys and a rubber belt making it extremely light weight and efficient.
Ackerman can be adjusted in three positions by replacing different inserts in the servo saver. The upper arm is adjustable with nine locations available to tune for any condition.
A rubber belt and Kevlar-contained resin pulley are also used for the rear drive system for high durability and smooth rotation.
A rigid machined aluminium break lever is included in the kit as standard. The brake has a highly-controllable feeling due to carefully-selected brake pad materials and the steel break disk.
The rear upper “I” arm is included in the kit as standard. It can be replaced with an “A” arm setup (option part) to accommodate a wide variety of track situations and driving styles.
Three kinds of fuel tank cap tips are included for various body shells and fuelling styles.
The receiver box protects the receiver from fuel and tire dust, reducing the chance of trouble during a race. It also makes the wiring simple.
The shock absorber is the same as the one included on the IF18 1/8th GP racing car. The single O-ring makes the operation smooth and stable. The shock piston has two 1.1mm holes each at the front and the rear.
