Castle Link™ ESC tuning is an essential component for customising vehicle performance for many Castle Creations’ customers. While the controllers are plug and play, optimising a Castle ESC through the Castle Link Programming Suite unlocks the full range of capabilities that set Castle apart from the competition. Users enjoy the ability to adjust many variables to enhance their experience including throttle, braking curve, drag brake, reverse type and more. The Castle B•LINK™ Bluetooth™ Adapter enables users to wirelessly program settings on current Castle Creations ESCs, many older models and the BEC 2.0/BEC Pro on Apple iOS devices. A complete listing of compatible ESCs and accessories can be found here. The free Castle Link app for iOS is available on the Apple App Store for use with iPhones and iPads, and once downloaded, it does not require a data connection and can be used anywhere, including remote areas. For Android users, a version of the app will be released at a future date, and the B-LINK adapter will be compatible.
