HSP Unlimited 110 Metal Tram Motor Gear Set 64T with Multiple Pinion Options

This metal tram motor gear set is a replacement part for HSP Unlimited 110 RC car drivetrains. It is supplied as a gear set with a 64T gear and a choice of pinion: 17T, 21T, 23T, 26T or 29T. The set is listed for teenagers aged 7-14 years and for unlimited applicable people, making it a practical option for RC hobbyists who maintain their own models. When an original gear becomes worn or damaged, replacing it with the correct specification helps keep the drivetrain running. The metal construction gives the gear a solid feel suited to repeated use in a motor gear position. Because the source data provides tooth counts rather than physical dimensions, use the tooth counts and your model requirements to select the right option. This is a straightforward replacement part rather than a complete upgrade kit, so check your existing setup before ordering.

Features and Construction

The gear set is built around a metal construction and a simple specification system. Each option pairs a 64T gear with one pinion tooth count, giving five choices for different drivetrain setups. The product is a single gear set, not a bulk pack, so it suits a targeted replacement.

Material and Build

The gears are made from metal, which is the only material stated in the source data. Metal is commonly used for RC car gears because it provides a firm, solid part that can handle drive transfer in a motor gear position. This set is intended as a tram motor gear for HSP Unlimited 110 models. No hardness ratings, coating details or wear-life figures are provided, so the practical expectation should be based on normal RC use and regular inspection. If teeth become worn or damaged, replacing the gear set is the appropriate action.

Size and Practical Fit

The available specifications are 64T 17T, 64T 21T, 64T 23T, 64T 26T and 64T 29T. In each case, the first number is the 64T gear and the second is the pinion tooth count. No diameter, pitch or shaft size measurements are given in the source text. To choose correctly, compare your existing gear tooth counts with the options listed. The 64T gear is common to every option, so the pinion tooth count is the main variable. Selecting the wrong pinion count may result in poor mesh or incorrect drive behaviour.

Uses and Placement

This gear set is intended for HSP Unlimited 110 RC car use and for general replacement of a tram motor gear. It can be fitted by users who are comfortable working on small mechanical parts. The age guidance is teenager 7-14 years, with unlimited applicable people also listed.

Event or Professional Use

For RC hobbyists, club runners or anyone preparing a car for a session, having the correct spare gear set can reduce downtime. The five pinion options allow a car to be kept close to its intended specification if the original tooth count is known. The metal construction is suited to the mechanical demands of a motor gear position. No performance gains, speed increases or competition certifications are claimed in the source data, so the set should be treated as a replacement part rather than a performance upgrade.

Everyday Home Use

At home, this set supports routine maintenance and repair of an HSP Unlimited 110 model. A parent or older teenager can keep the gear set on hand for when a gear strips or wears. The single-set format means there is no excess packaging or unused bulk. Because only tooth counts are provided, it is worth checking the model manual or counting the teeth on the existing gear before ordering. Fitting should be done carefully, with the gear mesh checked before the car is run.

Benefits and Buying Value

The main value of this product is as a targeted replacement for a specific RC car gear position. It offers a choice of five pinion tooth counts while keeping the same 64T gear, which simplifies selection once the required pinion size is known.

Reuse and Low Maintenance

Metal gears can be inspected and cleaned as part of normal RC car maintenance. This set does not include a maintenance schedule or care instructions, so use low-risk practices: keep the gears free from grit, check for worn teeth, and replace them if damage is found. Replacing only the worn gear set can be more practical than changing unrelated parts. No lifespan or service-interval claims are made in the source data.

Why Choose This Product

Choose this set if you need a metal tram motor gear for an HSP Unlimited 110 and you know which pinion tooth count your model uses. The five options cover 17T, 21T, 23T, 26T and 29T pinions paired with a 64T gear. The part is listed for teenagers aged 7-14 and unlimited applicable people. It is a focused, factual replacement product with clear tooth-count specifications and no unsupported claims about speed, durability or performance.
