Technical Performance
The brass construction of this counterweight provides the density and consistency required for precise weight management in 1:24 scale RC applications. Brass offers superior properties compared to lighter polymers or painted steel alternatives, maintaining dimensional stability across temperature variations and delivering consistent performance whether you're driving in indoor climate-controlled environments or experiencing the UK's variable outdoor conditions. The engineering behind this counterweight focuses on optimising the centre of gravity of your K5 Blazer model, which directly influences how the vehicle responds to throttle input, braking forces and cornering loads. For drivers seeking to improve lap times or achieve smoother, more controlled handling characteristics, weight distribution tuning represents one of the most cost-effective modifications available. This component integrates with the transmission and drivetrain assembly of your FMS K5 Blazer, working in harmony with the vehicle's existing suspension geometry and motor specifications to create a more balanced, responsive driving experience.

Frequently Asked Questions
- Why would I need a brass counterweight for my FMS K5 Blazer RC car? — Counterweights are tuning components that adjust the weight distribution of your RC model, improving handling balance and cornering stability. The brass construction ensures consistent weight and durability, allowing you to achieve more predictable handling characteristics during driving, whether on carpet, tarmac or outdoor surfaces. This is particularly valuable if you're experiencing understeer or oversteer issues with your standard setup.
- Is this upgrade suitable for beginners? — Whilst counterweights are tuning components typically used by enthusiasts optimising their vehicles, they are straightforward to install and do not require advanced mechanical knowledge. If you're new to RC car modifications and want to explore performance tuning, this is an excellent starting point. However, this component assumes you already own an FMS K5 Blazer 1:24 scale model.
- How does this compare to other weight tuning options? — Brass is the preferred material for RC counterweights due to its superior density and consistency compared to alternatives like aluminium or plastic. The precise engineering of this FMS component ensures it works optimally with the K5 Blazer's existing systems, delivering more reliable results than generic counterweights.
- Will this work with other RC car models? — This counterweight is engineered specifically for the FMS FCX24 12403 K5 Blazer 1:24 scale model. Whilst it may physically fit other vehicles, it has been validated and optimised only for the K5 Blazer platform, so we recommend using it only with that model to ensure proper performance.
- What is the return and warranty policy on this part? — FMS offers a comprehensive 30-day return policy for new and unused products purchased directly, covering defective items, Dead On Arrival components, shipping damage, loss or missing parts. Electronic accessories from FMS include a 90-day warranty from the date of delivery, along with access to long-term official technician support.

If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.

Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
