HPI Savage X 4.6 GT-6 Blue 1/8 4WD Nitro Monster Truck 160585

The HPI Savage X 4.6 GT-6 Blue brings the legendary Savage nitro monster truck platform up to date with a powerful F4.6 V2 big-block engine, strengthened drivetrain, aggressive GT-6 body and heavy-duty running gear built for serious RC bashing. Designed for drivers who want the sound, tuning and mechanical experience of nitro power, the Savage combines huge torque with the rugged construction that made the platform famous.

Power comes from HPI's Nitro Star F4.6 V2 pull-start engine, producing nearly 3 horsepower and capable of pushing the Savage X 4.6 beyond 45mph / 73km/h in suitable conditions. A fully adjustable 2-speed transmission helps deliver strong acceleration and high-speed performance, while 0.9mm clutch springs provide higher-RPM engagement for increased acceleration and reduced clutch wear.

The GT-6 specification adds the Super HD drivetrain shared with the Savage Flux, Bulletproof 29/9T differentials, standardised 17mm aluminium hex hubs and large TREDZ HD Terrahex 3.8" tyres on Havok wheels. Four XL big-bore oil-filled shocks, independent double-wishbone suspension and the 2.5mm aluminium Twin Vertical Plate chassis provide the strength and suspension control required for jumps, rough terrain and hard bashing.

How fast is the Savage X 4.6? HPI states that the F4.6 V2 engine produces nearly 3 horsepower and can propel the Savage X 4.6 to speeds exceeding 45mph / 73km/h in suitable conditions.

Does the Savage X 4.6 have reverse? No reverse system is listed as part of the standard 160585 GT-6 specification.

Does it have a 2-speed transmission? Yes. The Savage X 4.6 GT-6 uses an adjustable 2-speed transmission that automatically shifts into the higher gear while driving. The shift point can be adjusted to change how early or late the transmission changes gear.

What engine is included? The truck comes with HPI's Nitro Star F4.6 V2 4.6cc big-block engine with a pull-start system.

Does it use a pull starter? Yes. The F4.6 V2 engine includes a pull-start system, so an external starter box is not required for normal starting.

What fuel does the Savage X 4.6 use? HPI specifies 16–25% nitro RC car fuel. Fuel is not included and must be purchased separately.

Is a glow igniter included? No. A suitable glow igniter and fuel bottle are required separately. HPI recommends its Nitro Starter Pack 160077 as one compatible option.

Are the shocks oil filled? Yes. Four large oil-filled adjustable coil-over shocks provide suspension damping and control over rough terrain and jumps.

What are Bulletproof differentials? The Savage X 4.6 GT-6 uses HPI's heavy-duty 29/9T differential design, developed to withstand the substantial torque and impact loads generated during monster truck bashing.

Is a nitro truck suitable for a beginner? The Savage is supplied with a steering-wheel radio system and is straightforward to drive, but nitro ownership requires additional setup and maintenance compared with an electric RC vehicle. Users need to understand engine starting, carburettor tuning, glow plugs, fuel handling, air-filter maintenance and after-run care.
