HPI Large Scale Fans, wir haben Euch gehört! Der ORIGINAL, AUTHENTIC, HPI Baja 5B ist ZURÜCK und bereit für Sie von Grund auf zu bauen! Die HPI SBK Kollektion von Self Build Kits wächst mit der Hinzufügung von nicht nur einem, sondern ZWEI HPI Kits im Maßstab 1:5! Fans von großen Off-Road RC-Modellen werden begeistert sein, ihren eigenen GAS- oder FLUX-betriebenen Baja 5B mit diesen neuen Self Build Kits zu bauen!

Als der HPI Baja 5B Buggy zum ersten Mal vorgestellt wurde, war Large Scale RC sehr teuer und für den durchschnittlichen RC-Hobbyisten nur schwer zu erleben. Durch die Verwendung von sehr haltbaren Teilen und innovativen Designmerkmalen brachte HPI den Off-Road-Großraumbuggy zu neuen Enthusiasten und läutete eine neue, GRÖSSERE Ära des RC ein! 

 Der HPI Baja 5B und der 5B FLUX sind beide mit extra großen und super robusten Fahrwerksteilen ausgestattet, die eine unglaubliche HPI Haltbarkeit aufweisen! Mit seiner fachmännisch konstruierten Verbundstoffaufhängung und den extra langen, einstellbaren HD-Dämpfern sowie den massiven, 3-teiligen Beadlock-Rädern aus hochschlagfestem Nylon ist der Baja 5B bereit für Vollgas-Rennen auf jeder Offroad-Strecke!



HPI large scale fans, we have heard you! The one and only original HPI Baja 5B is BACK and ready for you to build from the ground up! The HPI SBK collection of Self Build Kits grows with the addition of not just one, but TWO 1/5th scale HPI kits! Fans of large scale off-road RC will be super excited to build their own gas-powered 1/5th scale Buggy with the HPI Baja 5B Self Build Kit!

When the HPI Baja 5B buggy was first introduced, large scale RC was very expensive and quite difficult for the average RC hobbyist to experience. Using highly durable parts and innovative design features, HPI brought large scale off-road to new enthusiasts and ushered in a new, BIGGER era of RC!

Now, YOU can build and own the legend! Experience the thrill and excitement of building a car which ends up being over 80cm (nearly 32 inches) long and weighing nearly 10kg (over 21 lb)! Just install your own engine and electronics as you build the HPI Baja 5B and you'll be ready for any adventure that comes your way!

With extra-tough drivetrain parts like the viscous torque differential, super-durable composite spur gear with internal damping and all-metal drivetrain, the HPI Baja 5B is ready for your 23-32cc 2-stroke engine so you can experience the joy of gas-powered RC and up to 30-minute runtimes!

The HPI Baja 5B is also equipped with extra-big and super-tough suspension parts, featuring awesome HPI durability! With its expertly designed molded composite suspension plus extra-long adjustable HD shocks, and massive high impact nylon 3-piece beadlock wheels, the Baja 5B is ready for full-speed racing on any off-road circuit!

The 4mm thick 6061 aluminum monocoque chassis gives the HPI Baja 5B the classic desert racing buggy look. Precisely bent into shape for maximum strength, the chassis provides the mounting points for the engine and suspension, forming the backbone of the car. Precise steering is provided by a dual-bellcrank rack and cam-type servo saver. Aluminum parts are anodized in cool gunmetal and the classic Baja desert racer clear polycarbonate body is included in the SBK kit, ready for your custom racing scheme!

The Baja 5B SBK is a great addition to your HPI collection, as well as a fabulous introduction to large scale buggies!

FLUXversion also available


The narrow channel chassis made from rigid 4mm 6061 aircraft aluminum and gives the HPI Baja 5B a classic desert racing buggy look and extreme stiffness and durability. The U-shaped chassis is protected at the rear with a thick plastic skid plate for extra protection to the motor and drivetrain.

The tube roll cage is made of high impact nylon and topped with a real aluminum roof to carry on the classic looks. The roll cage is fully functional and protects the motor and internals from crash damage. The roll cage, radio box, body panels, wing, undertray and gear case are all mounted with fast access clips for easy maintenance.


Building an HPI SBK (Self Build Kit) not only gives you the joy of assembling your own custom vehicle - you'll also be able to install an engine and your own electronics package as you go! Whether you buy all-new components or use an engine or  electronics that you already have on hand, the HPI Baja 5B is ready and waiting for you to go wild!


Specially constructed high-impact nylon 3-piece bead lock wheels are included, featuring NEW inset heavy-duty metal hex hub inserts for massively increased wheel durability. The contrasting beadlock ring is bolted onto the wheel with 20 screws to securely hold the tire in place. No glue is used to mount the tires, which makes changing the tires quick and easy and the wheels can be used again with brand new tires.

To allow the HPI Baja 5B buggies to go anywhere, Dirt Buster off-road tires are included that are ideally suited for off-road conditions. The Dirt Buster S Compound rear tires use a versatile square pin design that sheds mud and gives amazing grip for massive top speed runs, while the Dirt Buster rib tires provide the direction and steering necessary for pinpoint accuracy on the track. The rear tires use a special high-density racing style closed-cell inner foam which are firmer and longer-lasting than standard open-cell foam inserts. The closed cell Insert allows the tires to keep their shape and offer greater grip levels in tougher conditions.



The legendary HPI Baja 5B Viscous Torque Control differential delivers the power to the rear wheels with smoothness and precision, starting with the unique composite spur gear with internal damping. The differential can be easily tuned by using differential oils of various viscosities. The metal alloy diff case is finned for extra heat dissipation and to keep the internal gears firmly in place. The HD diff outdrives or cups are machined from hardened metal for reliable performance in all conditions. The internal gears are also made from hardened metal to handle huge power, big-air jumps and huge top speeds!





The 9mm thick Super Heavy Duty Drive Shafts and matching HD drivetrain parts add a serious amount of toughness to the drivetrain, and the rubber boots keep mud and grass from the outdrives and bearings.


The one-piece Rear Hub Carriers are easier to adjust, more durable, and are a lighter weight than the original multi-piece hub carriers. They also allow toe-in adjustments of 0, 1, 2, 3, and 4 degrees to help match the Baja’s performance to track conditions.


Replacing the original C-clip front hex hub, the HD Front Hex Hub adds a serious amount of strength to the front suspension and dramatically improves the durability of the HPI Baja 5B.


Along with their obvious HUGE size, large scale RC kits are known for their extra-long runtimes - and the HPI Baja 5B is no different! The massive 700cc fuel tank is big enough to allow a 23-26cc size engine to run for up to 30 minutes at top speeds (larger engines will have a shorter runtime)! With the tank located centrally in the chassis, there is no change in handling as the fuel is used up. All required fuel and expansion lines are included in the HPI Baja 5B SBK. Note: the fuel tank should NOT be refilled while the engine is running. Make sure to shut down the engine completely before removing the fuel tank cap.


The size, speed and durability of the Baja 5B make it the ultimate bashing buggy! Any field or vacant lot can become a race track when you've got a car nearly a metre (or yard) long! Ruts, roots, puddles and jumps that would stall or stop smaller RC vehicles are no match to the size of a large scale buggy like the Baja 5B! The wide and long-stroke suspension combined with the Super Heavy Duty drivetrain will keep you driving for hours!


The HPI Baja 5B SBK features long-stroke off-road suspension with huge coilover shocks featuring Heavy Duty construction. The HPI Baja 5B's HD shocks deliver improved handling over rough terrain and feature extra-large 6mm diameter shock shafts for ultimate durability. The rear shocks feature dual-rate springs for optimal traction on rough terrain. Threaded shock bodies are used for easy adjustment of ride height and pre-load, and each Baja Big Bore shock features extra-long springs, rubber shaft seals and all-metal body construction for consistently perfect control on all types of off-road terrain.
