3.5 NITRO POWER,
TROPHY TOUGH!
The Trophy Buggy 3.5 is the perfect way to get into nitro 1/8 buggies! Rallycross buggies are one of the biggest racing classes around the world, and it's still growing fast! The RTR Trophy Buggy kit has got everything you need for anything you want to do, whether it's racing wheel-to-wheel on the track with your friends or going to the park for all-day bashing like top speed runs and big-air stunts!

No matter what you want to do with the Trophy Buggy 3.5, it's ready for action. It's equipped with a durable aluminum chassis, braces and shock towers, long-travel shocks and grippy racing tires for top performance on and off the track. The Trophy Buggy 3.5 is equipped with a powerful and race-legal Nitro Star F3.5 (.21 cubic inch) HPI engine, HB Proto design racing tires, oil-filled shocks, turnbuckles and plenty of tuning adjustment possibilities that can take you to the top of the podium.

In addition to being race-bred and ready for track action, the Trophy Buggy 3.5 looks great, too! The sleek aerodynamic racing body features a bright paint design that's easy to spot on the track (or really high in air!), and the HB Proto tires are wrapped around cool black chrome Edge 7-spoke wheels. The rear wing isn't just for looks, either - it gives the buggy loads of downforce and precise control over the jumps as the car is in the air. To top everything off, the shock caps, wheel nuts and chassis features are anodized a bright HPI orange!

The Trophy Buggy 3.5 is completely painted and fully assembled right out of the box, so all you have to do is break in the engine and install the included AA batteries. With the HPI 2.4GHz radio system, Nitro Star F3.5 engine and all other electronics already installed, all you need to provide is the nitro car fuel, fuel bottle and glow plug igniter to get started.

All HPI vehicles are equipped with a comfortable and feature-packed HPI 2.4GHz radio system for supreme control and confidence! The radio features a pistol-grip design with steering wheel for ease of use and realistic control, compact size, servo reversing and a light weight 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, an electronic failsafe will bring it to a safe and controlled stop.

The Nitro Star F3.5 V2 engine provides the grunt needed to get the Buggy 3.5 up to wild speeds - it's loud, it's powerful and it's strong, so you'll be able to rip off huge stunts like record-setting long jumps, backflips, tall jumps, even double backflips! The F3.5 V2 engine is lighter and more energy-efficient than the V1 engine used in the first Trophy buggy, so you'll get even BETTER acceleration and HIGHER top speeds!

The engine is started by a simple pullstarter system and is protected by a unique water splash cover and 2-stage air filter for extra protection, and the two-needle carburetor allows you to fine-tune the performance for any kind of weather or fuel. One added benefit of the Nitro Star F3.5 is that it's a race-legal .21-sizeengine, which means you can drop down to your local track or club and enter in a race as soon as you open the box!

CHASSIS
The chassis of the Trophy Buggy 3.5 is made from 6061 aluminum for an excellent combination of strength and light weight. The low weight allows for faster acceleration, and the durability means you can have the confidence to pull off insane stunts and jumps!

To increase the chassis stiffness, it's fitted with metal rod braces front and rear - this allows the suspension to do all the work it's designed to do for improved driving feel and control without chassis twist or bending getting in the way.

DRIVETRAIN
The drivetrain used in the Trophy 3.5 buggy is a full-time four-wheel drive shaft-type drivetrain. The shaft drivetrain is the best option for a kit that's expected drive through mud, water, dirt, grass, snow or gravel! The entire drivetrain is supported by high quality ball bearings for extra efficiency, so you get the the maximum speed and acceleration possible, and the most out of every tank of fuel! A steel spur gear takes the power from the engine and transmits it through a central differential, which transfers power to the front and rear diffs by long central driveshafts. The front and rear bevel differentials use 4 internal gears for excellent durability over standard 2-gear diffs. The diff outdrives turn tough steel outdrives and axles, and 17mm orange anodized aluminum hex adapters spin the 7-spoke wheels, which are wrapped with Team HB Proto design rubber racing tires. To bring the Trophy to a safe and controlled stop, dual drilled steel disc brakes with fiber brake pads are used. The brake pads use material from full-size truck brakes, bringing the Trophy to a quick yet controllable stop. All the brake linkage is fully adjustable for extra tuning power on the track.

SUSPENSION AND STEERING
The Trophy Buggy 3.5 is fully equipped with a real racing suspension to give you the driving feel and responsiveness of the pros! Long suspension arms at each corner are made from thick, impact-resistant plastic and webbed for extra strength. The shocks feature aluminum bodies and caps for extra durability and are oil-filled with rubber bladders and protective boots over the thick shock shafts. For pro-level race tuning, you have complete control over the suspension geometry of the Trophy buggy. The shocks can be moved at the top and bottom to get the perfect positioning to help you set fast laps race after race. The camber links front and rear also have extra holes to adjust roll center and gain valuable seconds out on the track, and the links themselves are strong steel turnbuckles so you can easily adjust the angle of the tires.

If you don't want to make any changes and just get out and drive, that's fine too! Absolutely everything is factory-fitted right out of the box, so you don't have to change a thing if you want to just start up the Trophy Buggy 3.5 and have some fun.

PERFORMANCE STRAIGHT FROM THE BOX
HPI makes it as easy as possible to get into RC racing action. The RTR Trophy Buggy 3.5 is completely pre-built and ready to go right out of the box! Everything is assembled and tuned for you by professionals - diffs, shocks, suspension and more are perfect before you even open the package. You don't have to do a thing to get going fast! HPI Ready-To-Run vehicles bring you the same high performance and quality that you'd expect from a high-end RC kit but with the added convenience of being factory pre-assembled to the highest standards - giving you a high performance RC car straight from the box!

FULL ASSEMBLY INSTRUCTIONS
Just like all HPI cars and trucks, you get a full, in-depth instruction manual with step-by-step instructions that allow you to easily disassemble and reassemble your car for maintenance and easy servicing.
