Battery Telemetry
Voltage range 3.0V-4.2V. 3.7V = 50%. Below 3.5V = land soon. Real-time voltage and percentage display.
Signal Strength
RSSI shows Wi-Fi quality. -50dBm = excellent, -70dBm = good, -80dBm = poor.
Flight Data
Altitude, vertical speed, attitude angles, accelerations.
Using Telemetry
Monitor during flight, identify issues early, log data for analysis.
