HPI 107012 TROPHY BUGGY 3.5 1/8 4WD NITRO BUGGY
Fully Featured Rallycross Buggy, now Waterproof with 2.4GHz Tech!
The HPI Trophy range of off-road racers has been updated with the latest in 2.4GHz radio technology, waterproof servos and a waterproof receiver & battery compartment! That's right: one of our most popular nitro kits ever now has been upgraded to make it a performer just about anywhere! The Trophy 3.5 buggy 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! This kit has got everything you need for anything you want to do. For bashing fun and big-air stunts, it has a durable aluminium chassis, braces and shock towers, and for race track performance and tuning the Trophy is equipped with a powerful race-legal Nitro Star F3.5 (.21 cubic inch) HPI engine, HB Proto design racing tyres, oil-filled shocks, turnbuckles and plenty of tuning adjustment possibilities. In addition to being race-bred and ready for track action, the updated Trophy 3.5 looks great, too. The sleek aerodynamic racing bodyshell features a brand new paint design, and the HB Proto tyres are wrapped around cool black chrome Edge 7-spoke wheels. The rear wing isn't just for looks, either - it gives the Trophy loads of downforce and control in the air. To top everything off, we've updated the anodizing of the shock caps, wheel nuts and more to HPI-spec bright orange!
Want to tackle that muddy bug? How about that stream crossing? A bit of rain about to fall? That's all fine for the Trophy! The Trophy 3.5 now features a cool waterproof electronics compartment for the receiver and receiver batteries and a pair of HPI SF-10W waterproof servos and finally a water-resistant air filter cover that allows you to keep running the Trophy 3.5 in truly extreme conditions! Please note: This HPI vehicle is designed to provide water protection so it can be driven in wet conditions (e.g. rain, snow, puddles). Not for submersion. Nitro engines are splash protected and require extra care when running in wet conditions. See manual for details.
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, an electronic failsafe will bring it to a safe and controlled stop. You'll have professional-level control in one easy RTR package!
The Nitro Star F3.5 V2 engine provides the grunt needed to get the Trophy 3.5 buggy 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 carburretor 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!

To get you going quickly, the F3.5 uses a pullstarter system, and a large opening on the underside of the chassis allows you to utilise a starter box for even faster engine starting. If you want to upgrade to simple engine starting, just install the #87130 HPI Roto Start 2 engine starting system for push-button engine starting!
Chassis
The chassis of the Trophy 3.5 buggy is made from 6061 aluminium 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 improveed 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 byhigh 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 aluminium hex adapters spin the 7-spoke wheels, which are wrapped with Team HB Proto design rubber racing tyres. To bring the Trophy to a safe and controlled stop, dual drilled steel disc brakes with fibre brake padsare 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 3.5 buggy 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 aluminium 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 centre 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 tyres.
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 3.5 and have some fun.
HPI makes it as easy as possible to get into RC racing action. The RTR Trophy 3.5 buggy 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!
