About this Gig
Did your drone crash, flip on takeoff, drift, toilet-bowl or throw EKF and vibration warnings? Send me the flight log and I'll tell you exactly what went wrong and how to fix it.
I read ArduPilot .bin/.tlog and PX4 .ulg logs every week, from 5-inch quads to 43-inch heavy-lift multirotors and VTOL planes. Recent work includes flight-control support for a DARPA Lift Challenge team.
WHAT I CHECK
- Vibration levels, clipping and FFT (notch filter needs)
- EKF, GPS, compass and barometer health
- Motor outputs, saturation and thrust margin
- Battery voltage sag and power issues
- PID tuning quality: desired vs actual rates
- Failsafes, mode changes and the exact crash sequence
YOU RECEIVE
A clear report in plain words: what happened, the root cause, and the exact parameter or hardware changes to fix it. Higher packages include the fixes applied to your param file and a review of your next flight log.

FAQ
Where do I find my flight log?
ArduPilot: Mission Planner > DataFlash Logs > Download (.bin files). PX4: QGroundControl > Analyze Tools > Log Download (.ulg). Not sure? Message me and I'll guide you step by step.
Which package should I choose?
Quick Log Check if you just want to know what went wrong. Diagnosis + Fix if you want the exact parameter changes applied. Full Fix + Tuning if the drone also needs PID and filter tuning plus a call.
My drone crashed and the log is short or corrupted. Can you still help?
Usually yes. Even a few seconds of data plus your parameter file, a video and a photo of the build often show the cause. If the log can't explain it, I'll tell you before you pay for more work.
