HotWire 3.0 Bluetooth interface and the HotWire 3.0 Bluetooth ESC programmer are wireless tuning tools for Tekin speed controls. They connect Tekin ESCs to Windows PCs, Android devices, and Apple iOS devices via Bluetooth, with USB connectivity on Windows for direct programming. They unlock data logging, adjustable high-voltage BEC settings, and other in-depth tuning options, so performance can be fine-tuned and firmware can be kept current. Designed for RC cars and trucks, these tools let you tune throttle response, braking, and other parameters from the pit or workshop. They also enable sharing track- and condition-specific profiles with teammates and accessing team driver setups. A HotWire adapter is required to connect to Tekin servos and the ESC receiver during programming.
