If you want to know the difference between the HPI Bullet ST and the MT. And, which one is the best then keep reading. Also, learn how fast the ST is and if the MT is waterproof.
HPI Bullet ST vs MT: Which One Is Better?
If You’re into track racing, love speed, and primarily operate on smoother surfaces, then the ST is for you. On the other hand, if you prefer off-road adventures, challenging terrains, and rugged landscapes then go for the MT.
The ST & MT Overview:
HPI Bullet ST (Stadium Truck):
The ST variant is designed for those who love speed and agility. The stadium truck design features a slightly lower profile with sleeker body lines, making it ideal for track racing and high-speed runs.
HPI Bullet MT (Monster Truck):
The MT, on the other hand, is a beast meant for tackling rough terrains with its larger tires and heightened suspension. It’s designed for those who seek adventure beyond the paved paths, perhaps in the backyard or on off-road trails.
- Speed: Generally faster due to its aerodynamic design.
- Handling: Better on smoother surfaces, such as tracks or paved roads.
- Suspension: Tailored for jumps and landings on relatively even terrains.
- Speed: Slightly slower compared to ST but packs a punch in torque.
- Handling: Superior on rough terrains and uneven landscapes.
- Suspension: Robust enough to absorb shocks from rocks, bumps, and other obstacles.
The ST’s design is more streamlined, which means there are fewer parts exposed to potential damage during crashes or tumbles. However, its lower ground clearance can make it more susceptible to scrapes on uneven surfaces.
Thanks to its robust build and larger tires, the MT can take on more challenging terrains without sustaining significant damage. The higher ground clearance means fewer scrapes, but its larger profile can mean more parts are exposed during accidents.
Both the ST and MT variants of the HPI Bullet series offer ample opportunities for customization. However, the choice boils down to what you aim to achieve:
- ST: If you’re looking to boost speed, aerodynamics, or track performance, the ST provides a better base.
- MT: For those aiming to tackle harsher terrains or enhance off-road capabilities, the MT serves as a superior starting point.
Prices may vary depending on the region and retailer, but generally, the MT, with its robust features, may come with a slightly higher price tag than the ST.
How Fast Is the HPI Bullet ST?
The speed of the HPI Bullet ST largely depends on its power source:
Nitro Version: The nitro-powered version of the Bullet ST can reach speeds of up to 35-40 mph (56-64 km/h) under ideal conditions. These figures can vary based on the nitro fuel percentage, tuning, and engine condition.
Electric Version: The electric version, on the other hand, is equipped with a powerful brushless motor and can achieve speeds in the ballpark of 30-35 mph (48-56 km/h) when paired with the recommended battery setup. Note that the speed can be influenced by battery voltage, capacity, and specific gearing.
Factors Influencing Speed
Several factors can influence the speed of the HPI Bullet ST:
- Tuning: Especially for the nitro version, how well the engine is tuned plays a critical role. Ensuring the right air-fuel mixture and maintaining the engine can help you achieve peak performance.
- Terrain: The Bullet ST can run on multiple terrains. However, smoother surfaces like tarmac or compacted dirt will generally allow for higher speeds compared to rough or loose terrains.
- Tires: The type of tire and its tread pattern can also play a role in the overall speed. Slick tires for smooth surfaces and more aggressive treads for off-road conditions can make a difference in the vehicle’s top speed and traction.
- Battery: For the electric version, the type of battery (LiPo or NiMH), its voltage, and capacity can influence the speed. A higher voltage battery can deliver more power to the motor, potentially increasing top speeds.
Is The HPI Bullet MT Waterproof?
Electronics: HPI has equipped the Bullet MT with water-resistant electronic components. The servos, electronic speed control (ESC), and receiver are encased in protective covers or boxes that shield them from moisture, making them able to endure wet conditions to a certain extent.
The chassis is designed to prevent water ingress. It features raised edges and sealed compartments that are intended to keep water away from vital components.
Limitations and Cautions
Though the HPI Bullet MT has features that protect it from moisture:
- Not for Submersion: It is crucial to note that the truck isn’t designed to be fully submerged in water. Doing so can damage the electronic components and affect its performance.
- Post-Exposure Care: If you’ve run your Bullet MT in damp conditions, it’s essential to clean and dry it thoroughly afterward. This will help prolong the life of the components and prevent potential damage from residual moisture.
- Warranty Considerations: While the Bullet MT is designed to handle moisture better than some RC vehicles, exposing it to water may void the warranty, depending on the terms provided by HPI Racing or the retailer. It’s always advisable to check the warranty details before putting your truck through wet conditions.
