ERS RC01 Gas Engine Tachometer
The ERS RC01 is a CDI gas engine tachometer, and it’s honestly pretty freaking cool that RadioMaster included the gas crowd too. It lets you monitor real-time RPM on gasoline engines so you can see how the engine is performing during different maneuvers. I don’t personally fly gas much, but for big 3D gas planes, this is a solid telemetry upgrade.
