By Off-Road Master in HPI Racing, RC Cars

The Bullet ST 3.0 is just one member of a family of HPI vehicles which are based around a durable 4WD shaft drivetrain, 2 shocks per wheel and double-deck aluminium chassis. The Bullet off-road trucks feature either Nitro Star 3.0 engines or silent Flux brushless motor systems, and are available in different off-road truck varieties. In short, you can get the precise flavour of off-road performance you want with the HPI Bullet!

The Bullet trucks use a 3mm aluminium plate-style chassis as the backbone, providing an extremely tough foundation for the suspension and drivetrain. The aluminium used in the chassis is the very strong 7075-T6 alloy, which is the best aluminium available in radio-controlled vehicles and military aircraft, making it the ideal material for something like the Bullet! For extra stiffness, the sides of the chassis are upturned and the aluminium radio plate also acts as an extra stiffening support.

Nitro Star G3.0 Engine

The ‘3.0′ in the Bullet ST 3.0 name stands for the powerful Nitro Star G3.0 engine, HPI’s latest .15-size nitro-breathing powerplant. It’s equipped with the latest modern features taken directly from much more expensive racing engines, yet it’s easy to tune and adjust so hobbyists of all skill levels can jump right in and have fun! You get the minimum of hassle with the maximum of wheel-spinning fun!

The Nitro Star G3.0 uses a sophisticated, heat-resistant composite slide carburettor for consistent settings at all temperatures and quick response in any conditions. With 2 adjustment needles, it’s simple to tune and simple to maintain. An accordion style rubber boot protects the internal mechanism from dust and mud. To protect the engine from power-robbing dirt, a dual foam air filter is fitted to the carb.

Protecting the engine from excess heat build-up is the large heatsink head and extra cooling fins on the engine case. Both are made from aluminium, which dissipates heat quickly and effectively. The black coating on the case and the dark silver head look great together, showing the Nitro Star G3.0 has a bit of style to go with all that power!
