§Analysis Suite
Everything You Need to Perfect Your Tune
Seven specialized analysis modules give you deep insight into every aspect of your flight performance.
03
Time Trace
Classic timeline view with Gyro, Setpoint, and Motor outputs overlaid. Toggle Stick Inputs and PID Terms with adjustable smoothing.
04
Filter Performance
Analyze noise frequency distribution with Power Spectral Density plots. Automatically estimates Gyro Filter, D-term Filter, and RC Smoothing delays.
05
Freq × Time
Heatmap showing how noise frequencies change over time. Identify transient noise spikes and resonance with customizable signal sources.
06
Freq × Throttle
The ultimate tool for diagnosing frame resonance. See which frequencies vibrate at specific throttle percentages with split-view comparison.
07
PID Error
Advanced scatter plots showing PID error versus stick input, color-coded by throttle position. Includes delay estimation via cross-correlation.
08
Flight Statistics
Comprehensive report card: Max G-Force, Rotation Rates, Vibration levels, Battery stats, GPS data, and Motor saturation analysis.
