FPV Drones Hub
Everything around my Flywoo Flylens 75 HD O4 2S — from ESC firmware through radio link and latency to complete PID/filter tuning, based on real blackbox flight data.
30-Day Flight Guide Learn to fly
Pure flying skills — from your first hover in the simulator to rolls, flips and power loops. With a difficulty level and directly playable training videos for each day.
To the 30-day guide →60-Day Flight Guide Advanced
Building on the 30-day guide — Split-S, matty flip, juicy, lines and real freestyle flows. With safety and technique notes for phase 2.

Step by step from start to finish: flash the ESC → configure Betaflight → set up the radio link → minimise latency → enable race mode → tune PID/filters → test flight → optimisation.
To the guide →ESC & Bluejay
Why Bluejay instead of stock BLHeli_S, the best PWM frequency, startup power and demag compensation for the GOKU F405 BGA 12A 4-in-1 ESC.
To the ESC guide →Betaflight PID & Filters v9.0
The complete tuning story: from the first estimate through correction with real factory data to the final configuration, verified against real flight data.
To the tuning history →Blackbox & Telemetry
How a specific gyro noise peak was found from real blackbox logs and CSV exports using FFT analysis — including a transparently retracted misjudgement.
To the data analysis →Radio Link & Latency
Setting up TBS Crossfire with the Jumper T15, choosing the right packet rate, and why the DJI Goggles 3 race mode is the biggest lever against latency.
To the radio link →Analysis Comparison Safety-relevant
Own blackbox analysis vs. an independent external analysis — clearly compared. Reveals safety-critical points (failsafe delay, crash recovery, motor imbalance).
