Overview

Control your Castle Creations ESC setup from the palm of your hand with the Castle B•LINK Bluetooth Adapter, an essential accessory for RC enthusiasts across the UK who demand precision tuning and wireless convenience. Whether you're running brushless RC cars, trucks, or aerial platforms, this innovative wireless adapter transforms your iPhone, iPad, or Android device into a powerful ESC programming tool. The B•LINK puts Castle Link tuning capabilities at your fingertips, enabling you to optimise performance parameters in the field without disassembly or complicated cable connections. For RC car UK enthusiasts, ready to run RC drivers, and competitive racers alike, this adapter unlocks the full potential of your Castle ESC investment.

Castle Link ESC tuning is recognised as an essential component for customising vehicle performance, and whilst Castle controllers offer plug-and-play operation, optimising them through the Castle Link Programming Suite reveals the full range of capabilities that set Castle apart from the competition. The B•LINK Bluetooth Adapter makes this tuning accessible and convenient, allowing you to adjust throttle curves, braking characteristics, drag brake settings, reverse type, and numerous other variables to enhance your RC experience. Unlike traditional PC-based programming that requires cables and desktop computers, the B•LINK lets you make critical adjustments at the track or field with nothing more than your smartphone or tablet.

This product represents a significant leap forward in RC accessory design, combining wireless convenience with a compact, weatherproof form factor that allows permanent installation in your model without adding significant weight or bulk.

Key Features

• Wireless Bluetooth Communication — The B•LINK enables seamless wireless interfacing with most Castle Link compatible ESCs and accessories, allowing you to change parameters and update firmware without any physical connections to your model, making field adjustments faster and more convenient than ever before.
• Compact and Lightweight Design — Measuring just 30.48mm x 20.55mm x 6.55mm (1.20" x 0.81" x 0.25") and weighing only 6.62g (0.23oz), this adapter is engineered to minimise weight impact on your RC vehicle or airframe, making it ideal for weight-sensitive applications where every gram counts.
• Convenient Waterproof Design — The weatherproof construction allows you to quickly adjust settings in the field without disconnecting or disassembling your model, and you can either leave it permanently installed or easily swap it between multiple models depending on your needs.
• Free App Download — The Castle Link app is readily available on both the Apple App Store for iOS devices and Google Play for Android devices, with no subscription or licensing fees required for download or use.
• Offline Functionality — Once downloaded, the Castle Link app does not require an active data connection, meaning you can programme your ESC in the most remote areas and at the track without relying on mobile signal or WiFi coverage.
• Multi-Device and Multi-Model Compatibility — The application can be used with multiple B•LINK Bluetooth Adapters simultaneously, or you can store model-specific information and use a single adapter across numerous different RC models, providing flexibility for racers and enthusiasts with multiple vehicles.
• Passcode Protection — A user-selectable 4-digit security code prevents unwanted tampering with your ESC settings, ensuring that only you can make adjustments to critical performance parameters.
• Cloud Sync Functionality — Create a free account to sync model information between multiple iOS and Android devices, allowing you to back up your configurations and restore them across different phones and tablets.

Technical Performance

The Castle B•LINK Bluetooth Adapter represents cutting-edge wireless technology applied to RC hobby electronics. This compact device communicates via Bluetooth wireless protocol with compatible Castle Creations ESCs, including current generation models, many legacy Castle ESC variants, and accessories such as the BEC 2.0 and BEC Pro units. The adapter's waterproof construction makes it suitable for permanent installation in outdoor RC vehicles and aircraft without fear of moisture ingress from rain or water splash. The extremely lightweight form factor—just 6.62 grams—ensures negligible weight penalty even on racing-focused builds where weight distribution is critical. iOS devices require iOS version 10.0 or higher, whilst Android devices require Android version 5.0 or higher to operate the Castle Link app. Firmware updates are fully supported on iOS devices through the Castle Link App, with Android firmware update support scheduled as a future app update. The engineering of this adapter demonstrates Castle Creations' commitment to wireless connectivity without compromising the reliability and robustness expected from professional-grade RC equipment.

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.

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.
