Compact Design The DSK-515 is capable of being placed in very small and tight builds. We eliminated un-needed angles to streamline the receiver casing and to make installation easier than ever before. The case also features added antenna support and an integrated antenna tube slot for those custom models that do not provide a route for the antenna installation. Gas Mode Failsafe Built into The DSK-515 is our newest failsafe mode for surface applications, Gas Mode Failsafe. Easyily selectable during binding, Gas Mode allows users to preset the failsafe position of all available channels. Additionally drivers can utilize SmartSafe ™ failsafe which drops throttle to the lowest point and holds the last known command on the rest of the available channels.  Supports Futaba style plugs
