Thanks for your input, BUT if you read the DX4S manual which I HAVE. It states how the Telemetry is displayed and the different types of sensors that can be monitored on the remote nothing about connection and in the SRS4210 manual which I have READ it states no information about the data port in the receiver. If the receiver is not a telemetry receiver as you state then what is the data port for? MY LHS told me i could plug in the temp sensor and it would work. The "dying" tradition is not dead but the "tradition of someone helping on a forum seems to be dying" enlighten me someone please
