Troubleshooting Symptom Index

Problem-first directory: connect active flight problems to technical terms

Flight Fault ReportPID / Mechanical Noise

"My motors are extremely hot after short flights"

Likely Cause:Heavy frame vibrations, loose arm screws, or over-tuned D-term gains in the PID control loops.

Corrective Action:Check frame tightness, tighten motor screws, lower your D-term multiplier, or turn on Betaflight RPM filtering.

[ISOLATE FAULT TERMINOLOGY]

Flight Fault ReportVTX / RF Penetration

"My video feed keeps getting lines and static"

Likely Cause:Antenna polarization mismatch, loose coaxial U.FL connection, or flying behind thick concrete walls.

Corrective Action:Verify VTX antenna match (LHCP/RHCP), check U.FL lock, increase VTX power setting (mW), or switch channels.

[ISOLATE FAULT TERMINOLOGY]

Flight Fault ReportESC / Motor Desync

"My quad randomly rolls upside down and falls (Desync)"

Likely Cause:ESC losing sensorless tracking alignment with motor stators during sudden throttle spikes.

Corrective Action:Raise ESC startup power to 0.50, raise motor timing to 22-25 degrees, or verify motor windings for copper burns.

[ISOLATE FAULT TERMINOLOGY]

Flight Fault ReportLQ & RSSI Loss

"My transmitter outputs "Telemetry Critical" warning alerts"

Likely Cause:Low transmitter power, bad receiver antenna placement, or excessive physical blocking between sticks and drone.

Corrective Action:Upgrade to ExpressLRS 500Hz, check receiver antenna placement, or increase transmit packet power (mW).

[ISOLATE FAULT TERMINOLOGY]

Flight Fault ReportGPS / EMI Interference

"My GPS Rescue cannot arm / does not lock satellites"

Likely Cause:GPS module mounted too close to high-noise digital video transmitters or action camera hardware.

Corrective Action:Isolate the GPS module far back on the tail plate, shield wiring with copper tape, and wait for 8+ satellites.

[ISOLATE FAULT TERMINOLOGY]

Flight Fault ReportLiPo / Internal Resistance

"My battery sag drops voltage rapidly on punchouts"

Likely Cause:High internal cell resistance due to aging batteries, cold conditions, or excessive current draw.

Corrective Action:Pre-warm batteries in cold weather, retirement of high-resistance packs, or fly high-C rated packs.
