Tamiya 18715 Copperfang FM-A Chassis Mini 4WD Kit - Tuners Edition  [18715]

Meet the Copperfang Mini 4WD

The Tamiya Copperfang on the FM-A chassis blends form and function for model racers who enjoy both styling and setup work. It is designed to give a responsive ride while offering visual appeal for display or competition.

Exterior lines and aerodynamic intent

Styled with rally and sport car cues, the Copperfang body is shaped to reduce air resistance and enhance stability at speed. Body panels are supplied in colour, so builders can leave the finish as is or customise with paints and decals.

Front midship FM-A chassis explained

With the motor positioned forward on the FM-A chassis, the Copperfang benefits from forward weight bias that smooths steering and helps when tackling rises and drops on a circuit. The chassis uses durable black ABS for repeated use.

How to upgrade and what to try

There are many upgrade routes to improve handling or speed. Typical options include:

• Motors: Fit either torque-focused or speed-oriented motors depending on course demands.
• Tires: Choose super hard low-profile tyres to lower rolling resistance and increase consistency.
• Gears: Adjust gear ratios to tune acceleration versus top speed.
• Dampers: Add dampers to control body movement on uneven sections.

Practical tuning and race formats

The FM-A layout makes routine adjustments straightforward, enabling quick swaps and checks between runs. Its characteristics suit twisty technical layouts as well as sections that reward stable airflow and steady speed.

For modders and racers who like to tune, the Tamiya Copperfang offers a dependable FM-A base and a distinctive shell. It responds well to common performance parts and provides a good platform for skill development.
