Greetings - I am using the R920X Orange receiver with my DX9 transmitter and so far everything is fine. I want to add the external telemetry sensor for main battery temp and 6s voltage. The telemetry sensor plugs into the "balancing" plug to detect voltage. Can this be left plugged in even when not in use and not cause a draw on the battery? I'd like to avoid removing the canopy after each flight if possible.. Thanks for your advice.
