ExpressLRS 4.1 and EdgeTX 2.12.2 are the useful current RC baselines
ExpressLRS 4.1.0 is the current 4.x release and adds refinements including less aggressive telemetry-loss callouts, bind-phrase management from the handset, voltage-sensor calibration and telemetry changes. EdgeTX 2.12.2 is the current maintenance release in its 2.12 line.

RC reliability depends on the whole chain: transmitter firmware, RF module, receiver firmware, telemetry and flight-controller integration.
Keep ExpressLRS major versions compatible across TX and RX, back up EdgeTX models before updates, and bench-test controls, telemetry and failsafe behavior before flight.
