From KAVAN RC Wiki

The KAVAN Smart PRO version 2.01 and later is compatible with Spektrum single-cable operation (Smart Throttle). To enable this function, just plug the red telemetry cable into receiver channel No.1 and keep the other (black) cable unplugged. You will be able to control throttle as well as receive telemetry. This approach is compatible with the AR10400T receiver family as well.
