HPI Racing is proud to announce our latest Ready To Run Nitro car: the RTR Nitro RS4 3 Evo! Aimed directly at the beginner-to-intermediate Nitro touring car market, this is an updated version of our Nitro RS4 3, packed with features designed to get new owners on the street or track faster and more conveniently than ever! With a more powerful engine, Roto Start System, 2-speed transmission, prepainted body and more, this is the RTR touring car of choice for any discerning new buyer!

The RTR Nitro RS4 3 Evo uses the same chassis and major components of the Nitro 3 series. Preassembled on a 2.5mm thick purple anodized 6061 aluminum chassis, the RTR 3 Evo uses a durable shaft drivetrain with a removable radio tray. An HPI TX-2 radio, receiver and servos provide for a reliable and trustworthy electronics package.

The heart of the new and improved RTR Nitro RS4 3 Evo is the brand new T-15 engine, providing more mid-range power and top end speed! A tall cast aluminum heatsink head on the T-15 keeps it cool and running smoothly, and the 2-needle carb allows owners to tune the engine precisely for their conditions. The included HPI Roto Start System lets the engine start up with push-button convenience! No more fumbling for a starter cord - just attach the glow plug igniter and Roto Start, hit the button and go! The T-15 breathes through a large pre-oiled air filter and our aluminum header/composite tuned pipe combo - a great way to get tons of power to the ground!

And we didn't stop with the new engine. Also installed on the car right from the factory is our 2 Speed Transmission! In addition to boosting top speed, our 2 Speed Transmission features an adjustable shift point and changeable gear ratios for extra tuning convenience. Now RTR Nitro car owners can experience the thrill of hearing and seeing their car shift from first to second gear!

Putting the power to the ground is a ball bearing-equipped durable shaft drive system featuring strong steel dogbones and sealed gear diffs. Oil-filled coilover shocks provide the suspension action and provide an extra bit of realism for full-size sports car fans.

Here are the major features of the RTR Nitro RS4 3 Evo:

• A shaft drivetrain prevents damage from pebbles and stones
• Full-time 4WD provides great handling on any paved surface
• Our brand new T-15 engine features a large heatsink head, 2 needle adjustments and ABC construction
• A limited-slip front diff makes driving easy and predictable
• The removable radio tray makes cleanup simple and quick
• 2.5mm countersunk chassis for a solid platform
• Dual chamber tuned pipe and tube header
• A complete set of rubber-sealed ball bearings
• The proven Airtronics radio system keeps things under control
• Pre-cut foam bumper keeps everything protected
• D-Compound X-Pattern tires grip just about everywhere
• Adjustable body posts let you fit a variety of HPI bodies

We wanted to make sure the car looks great, too, so topping off each RTR Nitro RS4 3 Evo is a prepainted, trimmed and decaled body, ready to go right out of the box. Choose from the high performance BMW M3 GT or the popular Dodge Viper GTS-R! HPI D Compound X-Pattern tires are preglued onto flashy chrome plated Split 6 wheels for awesome looks and performance!

The RTR Nitro RS4 3 Evo is a terrific way to get introduced to Nitro R/C! Because it is completely assembled, getting started is just a matter of about an hour's worth of work, and you're off and running!

Cleanup couldn't be easier, either - with a covered receiver case, fully enclosed battery compartment and removable radio tray, it's just a matter of spraying off the chassis with our #9062 Nitro Car Cleaner to get rid of road dirt.

Easy to Upgrade!
In addition to any of our 200mm touring car bodies, the RTR Nitro RS4 3 Evo can also accept any of our touring car wheels, treaded or slick tires, shocks, springs... it's all available and waiting to fit your car! In the HPI tradition of parts compatibility, many of the drivetrain hop-up parts from our popular Nitro RS4 MT will bolt right on. Of course, there are several hop-ups available just for the RTR 3 Evo, including a stronger chassis, graphite upper deck and many more to come. We even have HPI brand Power Fuel, Nitro Start-Up sets, fuel bottles, and Nitro Car Cleaner available so you can get rolling as quickly and easily as possible. See our Option Parts page for all the items you will need!

Terrific value!
Our new RTR Nitro RS4 3 Evo is the successor to the hugely popular RTR Nitro RS4 3, and is currently available from your favorite retailer.

Great radio!
The HPI TX-2 radio system included with HPI RTR kits is packed with features! The super narrowband AM transmitter and receiver work together to let you precisely control your car. Six different crystal choices let you race with your friends!

The radio transmitter is comfortable to hold and features a battery strength indicater, letting you know when the batteries need to be replaced or charged. The transmitter also features a retractable antenna, steering and throttle trim dials (for fine adjustments to center the servos), plus a dual rate adjustment for the steering! Dual rate is very important because it lets you adjust how far the steering servo turns the front wheels left and right.

Two strong servos are also installed in each HPI RTR Nitro kit, already plugged into the standard size super narrowband AM receiver. A convenient on/off switch is also included!

If a warranty issue is ever encountered, Airtronics handles all USA returns and repairs. Upgrades are also available from your local hobby shop!

Four AA batteries are needed to fit in the car battery holder, with 8 AA batteries needed for the transmitter.
