FPVtune

What is FPVtune?

FPVtune is an innovative AI-powered online tool designed specifically for FPV drone pilots. It automates the complex process of Betaflight PID tuning by using a neural network to analyze blackbox logs. Instead of spending hours on manual adjustments and test flights, users can upload a .BBL or .BFL file from Betaflight 4.5 and receive optimized PID values, filter settings, and feedforward gains in under 30 seconds. The tool provides ready-to-paste CLI commands, gyro noise spectral analysis, motor thermal predictions, and supports various drone configurations from tiny whoops to X-class builds. It aims to make professional-grade tuning accessible to pilots of all skill levels, eliminating guesswork and reducing the risk of damaging motors.

Main Features

- Neural network analysis of gyro noise and resonance frequencies.

- One-click CLI export for direct use in Betaflight Configurator.

- Motor thermal prediction to prevent overheating from aggressive tuning.

- Dynamic filter tuning for gyro lowpass, D-term lowpass, and notch filters.

- Prop wash elimination optimization through D_min, D_max, and feedforward adjustments.

- Support for multiple ESC protocols (DShot150 to DShot600, bidirectional) and gyro chips.

- Flying style presets for freestyle, racing, cinematic, and long-range.

- Hangar feature to save hardware profiles and reuse them across tuning sessions.

- AI tuning memory that improves recommendations over time.

- Downloadable PDF reports (Pro and Plus plans).

- Priority processing with under 5-second queue (Pro and Plus plans).

- Tune history timeline (Pro and Plus plans).

- Crash Analyzer, Motor Health Check, and Flight Time Calculator tools included free.

Use Cases

- Rapid PID tuning for racing drones to achieve crisp, responsive handling.

- Optimizing freestyle quads to eliminate prop wash and improve stability during tricks.

- Tuning long-range and cinematic builds for smooth, efficient flight.

- Diagnosing and fixing oscillation issues, hot motors, or sluggish response.

- Checking motor health and identifying worn bearings or damaged props before failure.

- Estimating flight time based on battery capacity and current draw.

- Analyzing crash logs to determine cause (desync, power loss, failsafe, etc.).

Supported Languages

- English

- Chinese (Simplified)

Pricing Plans

- Quick Tune: $9.90 per tune, one-time payment. Includes full BBL analysis, CLI commands, instant results, and hangar profile storage. No PDF report, priority processing, or tune history.

- Pro: $27.92 per month (billed yearly at $335, saving 30%). Includes 15 tunes per month ($1.86 per tune effective). Adds PDF reports, priority processing (under 5s queue), and tune history.

- Plus: $48.83 per month (billed yearly at $586, saving 30%). Includes 40 tunes per month ($1.22 per tune effective). Same features as Pro with higher quota.

- Refund policy: 7-day full refund if no tunes consumed. Once a tune is used, no refund but subscription can be canceled to stop renewal.

Frequently Asked Questions

- Why should I subscribe instead of paying $9.90 each time?

If you tune more than 2 times in a month, Pro pays itself back at $39.90 for 15 tunes (about $2.66 per tune, 73% off). Subscribers also get PDF reports, priority processing, and tune history.

- What's the refund policy?

You can get a full refund within 7 days of subscribing if you haven't used any tunes. Once you use a tune, the subscription is locked but you can cancel to stop future renewals.

- What happens when my monthly quota runs out?

You can purchase additional tunes at the per-tune rate or wait until the next billing cycle for your quota to reset.

- Can I cancel anytime?

Yes, you can cancel your subscription at any time. Cancellation stops future renewals, but you keep access until the end of the current billing period.

- What's the difference between Pro and Plus?

Pro offers 15 tunes per month, while Plus offers 40 tunes per month. Both include PDF reports, priority processing, and tune history. Plus is better for squads or heavy users.
