HPI Savage
From Wikipedia, the free encyclopedia
The HPI Savage is a 1/8th scale radio controlled monster truck manufactured by HPI.
The original version was the now-discontinued Savage 21 which served as the basis for the vehicles that came after. It featured a two-speed transmission, heavy-duty slipper clutch, four-wheel-drive, HPI .21ci³/3.4cm³ pull-start engine with rear exhaust and a HPI 27 MHz three-channel pistol grip radio. A "reverse module," sold separately, mounts inside the transmission and utilizes the radio's non-proportional third channel and an additional servo to add the convenience and fun of reverse when the model is first brought to a complete stop.
The Savage 21 was replaced by the updated Savage 25. This version added both a larger HPI .25in³/4.1 cm³ engine for additional power and torque as well as HPI's unique Roto-Start electric starter system. The Roto-Start kept the weight-saving advantages of the pull start with the extra added convenience of electric starting via an external electric starter. This starter, standard on most new HPI models, incorporates a gear-driven one-way bearing mounted on the engine in lieu of the pull starter. The external starter is a motor-driven gearbox which spins a steel shaft and is powered by a standard 7.2v Ni-Cd battery pack. A pinned ball joint similar to those found on "dogbone" axles mates with a socket on the rear of the engine. An limited edition version of the Savage 25 added a three-speed transmission along with updated wheels and tires. These parts can easily be retrofitted to previous versions. A mechanically identical variation of the Savage 25 replaces that model's Lexan pickup truck body with that of a Kawasaki KFX700 all-terrain vehicle with articulated rider figure designed to move with the models's steering motions.
Hpi made later new model, the 4.6 savage. the car has heavy duty dogbones and the new engine gives out 2.9 bhp and is better overall than the previous savages. the new engine has 10% more displacement than the s-25.The latest(as of 2005)model is the "Hellfire". It has a more powreful engine, with 2.95 hp, and is desinged purely for racing.
