Horizon Hobby has a $39.oo sensor that plugs into the JetCat GSU Interface port. Then the interface plugs into a TM1000. This give me all the JC data on the Txer screen. The Txer then can be set up with alarms for things like ECU Battery Voltage, High Temp, Flame Out, excessive RPM, etc. Works great for monitoring the JC functions and it is only $39.
