Control at your fingertips!

Castle Link™ ESC tuning is an essential component for customizing vehicle performance for many Castle Creations’ customers. While the controllers are plug and play, optimizing 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 and now Android devices!
