Overview
Building on the success of the COBRA 10 and COBRA 8, we are excited to announce the release of the all-new COBRA 5, engineered for 1/7th and 1/5th scale high-performance RC applications! The COBRA 5 is designed to deliver precision, durability, and unmatched power-handling capabilities.
New tuning parameters include adjustable braking curves and independent reverse settings to reduce the risk of broken gears, snapped driveshafts, and blown differentials, all while experiencing smoother transitions. Users will feel a more realistic and predictable driving experience while saving their drivetrain from unnecessary stress.
Whether tweaking the suspension or altering tire pressure, data-driven decisions lead to optimal performance in an R/C vehicle, and the COBRA SERIES enhanced data logging includes double the maximum sample frequency of older generations, providing more granular data for analyzing performance. Gone are the days of clearing data logs-users will experience increased logging time and enjoy the new looping feature that prevents interruptions in recording. New data points for ESC electrical motor timing and acceleration via the onboard accelerometer provide insight into needed adjustments to detect tire slippage or fine-tune motor efficiency.
The COBRA 5 is packed with a potent combination of hardware and software advancements, making it an indispensable ally in high-performance power systems. Users will benefit from the same footprint as its predecessor, the Mamba XLX2, while an upgraded current-sensing and thermal protection system actively mitigates the risk of failure in aggressive or high-load setups. The COBRA 5 is available to purchase as an ESC-only option or packaged with three Castle 4-POLE 12-SLOT motor options to overpower a wide range of 1/7th and 1/5th scale vehicles

- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. 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.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. 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.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
