What Does HSP Stand for in RC Car?

Radio-controlled (RC) cars are incredibly popular hobby vehicles that have been around since the 1960s. One of the most important components of an RC car is its drivetrain, which is responsible for propelling the car forward and controlling its speed.

The drivetrain can be powered by electric motors, nitro engines, or gas engines. A popular type of drivetrain used in electric-powered RC cars is a High Speed Pinion (HSP) system.

An HSP system utilizes a small pinion gear attached to the motor shaft that meshes with a larger spur gear located on the axle of the car. As the motor spins, it turns this smaller pinion gear which in turn rotates the larger spur gear. The larger spur gear has teeth that are wider than those on the pinion gear, so as it rotates it delivers more torque and power to the axle, allowing for higher speeds than other types of drivetrains.

In addition to providing greater speeds than other drivetrain systems, HSP systems are also lightweight and compact so they don’t add significant weight or bulk to an RC car. This makes them popular for experienced racers looking to get more performance out of their cars without compromising on weight or size.

Another advantage of HSP systems is that they are relatively easy to maintain and repair as compared to some other types of drivetrains. This makes them ideal for both beginner and advanced RC car users alike who want a reliable and low-maintenance system.

In conclusion, HSP stands for High Speed Pinion and is a type of drivetrain commonly used in electric-powered RC cars. It utilizes a small pinion gear attached to the motor shaft which meshes with a larger spur gear located on the axle of the car resulting in increased torque and power output. In addition, these systems are lightweight and compact as well as easy to maintain making them popular among both novice and experienced racers alike.
