Castle Link™ ESC tuning is an essential component of customization for many of our customers. While our controllers are plug and play, the benefits of fine tuning your Castle ESC through the Castle Link Programming Suite have only reinforced the sophistication and value of the Castle brand. Not only do you get the ability to adjust many variables to enhance your experience, you have the assurance that firmware updates for future features and improvements for your controller are provided at no cost to you. Discover just how easily and quickly you can reign in tuning with the release of the Castle B•LINK™ BLUETOOTH® ADAPTER, which will allow most Castle Link compatible products to be programmed via Bluetooth enabled mobile devices using our free application, with firmware updating to be added soon.

The initial release is supported on Apple iOS platforms only; for Android users, a version of the app will be released at a future date, and the B-LINK adapter will be compatible. All current Castle Creations ESCs, many older units and the BEC 2.0 and BEC Pro are supported,
