HPI 1/8 Savage X 4.6 Big Block RTR Monster Truck

The RTR Savage X 4.6 is the fastest and strongest ready-to-run Savage… EVER! That's right, we've raised the bar by adding a massive F4.6 engine and beefed up the chassis and drivetrain to handle the power. The result is a truck that has enough Big Block power to do wheelies on command with a scorching top speed of more than 45 MPH. A huge list of performance and durability upgrades come standard in the RTR Savage X 4.6, so you know that you've got a truck that can handle extreme off-road driving.

New Option Parts Included As Standard!
Included with the Savage X 4.6 are two of the latest option parts: Alloy Diff Cases and new stronger brake disks! The Alloy Diff Cases prevent damage to the internal diff gears, even with the power of a Big Block engine. The result is more driving and less maintenance! New dual disk brakes provide more stopping power and are more fade-resistant than ever!

Savage X 4.6 Durability
Eight long coil-over shocks absorb any type of rough terrain you can throw at the RTR Savage X 4.6, and beefy suspension arms and uprights can take the punishment of big-air drops and top speed runs over bumpy terrain. Keeping everything protected is the reinforced "X" TVP chassis, which features a custom 'X' graphic. Structural webbing and extra screws have been added to the central gearbox to improve durability, and add stiffness. Extra material was added to the skid plates and bumper to help the Savage X 4.6 survive huge jumps and crashes. The engine mount and engine plate are now thicker to give you more durability and endurance, especially when you're landing massive jumps!

Savage X 4.6 Speed
The new F4.6 powerplant is designed for one thing and one thing only - huge amounts of horsepower! Nearly 3hp, in fact! Enough horsepower to get the Savage X 4.6 up to 45mph (73kph)! And Big Block TORQUE is always on tap, just pull the throttle and you'll know you're not driving a small block. You want speed? You want torque? You've got it!

The F4.6 engine is a new HPI high-power unit with the proven HPI Nitro Star reliability, featuring 2.9hp from its .28 cubic inch displacement! A purple anodized machined aluminum cooling head keeps the engine cool. Rough off-road terrain and extreme stunts are not a problem with this engine! The F4.6 features true ABC construction (Aluminum piston, Chrome-plated Brass sleeve), 8 port tuning, a 7.5mm composite carburetor, heavy duty triple shoe clutch, plus an updated Roto Start 2 electronic starting system for easy starting. A dual-stage air filter protects the F4.6 from dust and dirt kicked up by the 4WD action!

The F4.6 engine is so fast, in fact, that HPI designers made significant improvements to the chassis, gear cases and other parts of the truck to beef it up so it could handle the extra power! The F4.6 engine pumps out nearly 3 horsepower and sits on an improved engine mount and thicker engine plate to give you more durability and endurance, especially when you're landing massive jumps!

Drivetrain
Our designers wanted to make sure the Savage X 4.6 drivetrain could handle the extra power of the Nitro Star F4.6. The Savage drivetrain features a permanent 4WD system and spins on rubber-sealed ball bearings, plus it features an adjustable 2 speed transmission. To add extra strength, aluminum alloy diff cases are now standard on the front and rear differentials, pre-installed and shimmed to extend the maintenance interval of the HPI 4-gear differential. The 17T clutch bell has been modified so it engages the spur gear with extra consistency. A steel spacer is used on the clutch bell, which provides more durability than the brass spacer. The adjustable slipper clutch features a slipper pad made from a more durable material, so there's less maintenance and more driving! Finally, to make sure you can stop this beast as quickly, the Savage X 4.6 is equipped with a new twin vented disk brake made from heat-resistant fiber material to give you more stopping power!

Easy Starting
The RTR Savage X 4.6 includes a Roto Start 2 starting system to get you up and running with minimal effort! To start your engine simply insert the Roto Start into the engine's back plate, press the trigger and away you go!

The Roto Start 2 features an engine save mechanism that protects the engine. The protection mechanism acts like a fuse. If an overload is caused by a flooded engine the fuse button will pop out and stop the Roto Start. After clearing out the flooded engine (as shown in the instruction manual) you simply push the fuse button back in and start the engine as normal.

RTR - Performance straight from the box!
HPI makes it as easy as possible for beginners to get into Nitro RC cars. The RTR Savage X 4.6 it is completely pre-built and ready to go right out of the box! Everything is assembled and tuned for you by professionals - diffs, slipper clutch, shocks and more are perfect before you even open the kit and with all the top Savage X options already installed, you don't have to do a thing to get going fast!
