The Inferno Neo ST Race Spec 2.0 ReadySet (RTR) is a factory-assembled, nitro-powered racing truck thatís got World and National Championship origins, built on a foundation that benefits from more than a decade of development and refinement.

The channeled aluminum chassis is made from stronger, more durable alloy. Itís supported at the front and rear bulkheads by molded chassis braces, which are allowed to flex more than rigid aluminum braces. For years this has been a performance secret of many Kyosho racing vehicles, because a more compliant chassis brace has been the key to superior traction and handing.

The bulkheads and suspension arms are taken right from the ST-RR Evo racing kit, and the three-differential drivetrain is so effective that its one of the most copied components in the history of RC racing. Front, center and rear differentials transfer power to the wheels via a strong shaft drive system with ultra-smooth front universal driveshafts. A double disc brake system provides ample stopping power, and itís adjustable to your liking if you decide to experiment.

Molded composite big-bore shocks are fitted with distinctive bronze anodized shock caps and threaded spring pre-load adjusters. The aluminum shock towers are fitted with steel upper shock mounts, and the lower ends of the shocks mount directly to the suspension. The shocks are fully adjustable of course, and they fit a wide range of optional performance racing springs developed for the ST-RR Evo truck. Front and rear anti-roll bars are also standard, as are turnbuckle tie-rods and upper suspension links for quick and precise adjustment.

The truck is powered by a Kyosho KE25 engine, which is in its second generation. Itís refined to include a stronger conrod for increased longevity, and the internals of the pull-starter have been tweaked for more reliable and easy starting. The pull-starter is unique in that it doesnít have a one-way bearing that can wear out. Once the engine is started, the pull-starter is completely disengaged. That means that no power is being lost and thereís no hardware needlessly spinning along with the essential engine components.

A polished aluminum header and tuned pipe mounted directly to the industry-standard rear exhaust port. The header and pipe are not only much lighter, but they help the engine to product much more horsepower. The engine is fed by a racing-truck-legal 150cc flip top fuel tank, which facilitates quick on-the-fly refueling.

The radio gear is updated to the NEO ST 2.0, featuring the KT-331P 2.4GHz radio with an LCD display and full range of menu driven adjustments. Metal gear KS-5031-09MW water-proof servos are fitted for throttle and steering. The layout of the radio gear in the NEO ST 2.0 is also significantly different, using the IGW051 ďBattery Forward Conversion Set,Ē the receiver battery and radio gear is moved as far forward as possible for more forward weight bias to enhance steering response.

Last but not least, the NEO ST 2.0 sports a livery featuring the Unique Energy Drink logos on a striking silver, black and bright red paint scheme.

excellent truggy, very fast . I'm new to rc nitro cars and this one really impressed me, the built quality is superb. You will pay a lot for this one but you won't regret it. The engine is easier to tune compare to my traxxas stampede small block engine and it runs much more cooler. Spend a little more and your fun levels will go up 50%.

I'm really impressed. Like with all Kyosho products, you get what you pay for. What can I say? Great truggy, easy enough to get up and running, needles are preset for break in. Develops tons of power and can throw itself clear over just about anything and still maintain control of itself.

I've never driven a truggy before, but with similar geometry to the MP9 (which I do have) it was a pleasure to drive. Even my wife can get it around without too much crashing.

All around great truggy, good radio.

Only down side was the tires were a little flattened from sitting in the box for too long, but from what I read this is common and if you really don't like it, tell kyosho about it, they are generally good about making sure you are happy.

Awesome quality and great motor the wife has more drive time than I do at this point after the break in and tune. Very controllable and has a great radio with plenty of adjustments the screen is great for knowing exactly how much trim. On a side note a 2į rear Anti sqat is a must for saving front tires.
