3D flight replay
Load a Blackbox log and watch the flight again in 3D: how the drone rotated, what the sticks and each motor were doing, with the goggles video synced alongside.

GPS track
How it works
Attitude, from the gyro
The log doesn’t store the drone’s angle, only how fast it’s rotating at each instant. The tool integrates that rotation rate thousands of times per second and, if the log includes the accelerometer, uses it to keep the horizon in place.
It rotates, but doesn’t move
Without GPS there’s no way to know where the drone was, only how it was oriented: you see it rotate in place, which is what you need to understand a trick, a bounce or a wobble. If the log includes GPS, you’ll see the track on a map below the flight and can download it as GPX.
Sticks and motors
In the corner you can see what your thumbs were doing and how hard each motor was working. If one motor always runs higher than the others, it’s a first hint of unbalanced weight, a damaged prop or a tired motor.
If the log doesn’t include the accelerometer (common on acro drones), the horizon may drift a little on long flights. Rotations and tricks look just as good. To analyse noise and tuning, use the FPV Assistant’s Blackbox tool.
