The excellent RTR Nitro RS4 3 Evo+ has been one of HPI's stand-out car kits, introducing many RC fans to the joys of Nitro RC driving. With the 2.2hp T3.0 engine you get an easy-to-use yet extremely powerful engine that's perfect for speed runs with your friends or racing at your local track! With the adjustable 2-speed transmission fitted, the car is perfectly suited for quick acceleration out of the corners as well as pure top-end speed! The full-time 4WD also gives you great acceleration, easy handling characteristics and traction on any type of paved surface. The HPI Nitro RS4 line of cars has historically been aimed directly at the beginner- to intermediate-level RC hobbyist, the driver who wants a fast car with great handling that's ready-made to go out and thrash the pavement - and that's exactly what the Nitro 3 Evo+ delivers! We aim to improve the kits whenever we can, and the RTR Nitro RS4 3 Evo+ is now fitted our latest radio gear, featuring 2.4GHz technology and waterproof servos!

All of the latest HPI kits are now fitted with a comfortable and feature-packed HPI 2.4GHz radio system for supreme control and confidence! The radio features a pistol-grip design with drop-down steering wheel, 3 channel functionality, easy carry handle, fold-down aerial, end point adjustments, servo reversing and steering dual rate. It's also extremely lightweight due to it requiring only four AA batteries. You won't have to worry about radio crystals or what channel other RC racers are using with our 2.4GHz technology - the radio does all that work for you! The radio prevents frequency conflicts automatically and changes channels if there is any interference. Finally, if you ever lose radio signal or battery power, an electronic failsafe will bring it to a safe and controlled stop. You'll have professional-level control in one easy RTR package!

FULLY ASSEMBLED AND PREPARED CHASSIS
We make things extra easy for you to get driving quick. The car is completely assembled by professionals and ready to go right out of the box, so all you have to do is add fuel and batteries to get running!
TWO SPEED TRANSMISSION
The standard two-speed transmission gives you a killer combination of fast acceleration and massive top speed! It's also easily adjustable so you can tune it for maximum speed attacks or for short, twisty circuits.
ALUMINIUM TUNED PIPE
To give the engine as much power as possible, a tuned exhaust system is installed to give the car as much low-end torque as possible, while allowing it to breathe as much as it needs to to get maximum revs for huge top speed!
SUPER TOUGH SHAFT DRIVE
The Nitro RS4 3's reliable shaft drive powers the wheels through a system of ball-bearing supported shafts and axles, so you get the maximum power available from the T3.0 engine. You won't have to worry about fragile belt drive systems getting stuck with rocks or pebbles!
STRONG DISC BRAKE
A powerful disc brake system gives the car efficient and strong braking power for quick turns and avoiding danger. It's easily adjustable to make the braking more or less intense, so you can dial in the braking force for the traction conditions you're racing in.
REMOVEABLE SEALED RADIO BOX
The easily removeable radio tray contains all the electronics for simple cleaning of the chassis, and keeps fuel and dirt away from the electronics. Body clips hold the tray securel in place and there's plenty of room in the main compartment for the standard 4 AA battery holder or the optional #101936 rechargeable 5-cell 'hump' battery pack.
INDEPENDENT DUAL WISHBONE SUSPENSION
Just like a real racing car, the Nitro RS4 3 features dual wishbones to provide all the suspension action, with a large lower A-arm and solid upper camber links. Oil-filled shocks with racing progressive springs control the movement of the arms, and are easily tunable - just like a full-size racer!
