ONDAS Tuning Guide
The practical companion to ONDAS Theory — how to tune each parameter by feel.
Tuning Order
ONDAS parameters are interdependent. Tune them in this sequence:
1. Cadence → timing
2. Ferocity D → primary stabilization
3. Ferocity P → response crispness
4. Balance → upstroke/downstroke bias
5. Warp → modulation width
6. Anchor → dry/wet mix
7. Resonance → cycle-to-cycle memory
8. Phase 2 → advanced (prescience, espelho, saudade, SSFF)
Step by Step
1. Cadence — Find Your Phase Window
Goal: Place modulation where your wing has the most bite.
Method: - Start at 50 - Increase to 70 — does roll response get weaker? - Decrease to 30 — does roll response get stronger? - The “strongest” point is where your wing’s power stroke peaks
Signs of too high: Mushy response, craft feels “delayed” Signs of too low: Jerky response, overshoot on roll
2. Ferocity D — Steady the Craft
Goal: Primary stabilization without oscillation.
Method: - Start at 20 - Hover or steady forward flight - Increase until you feel the craft “stiffen” - Back off 5 points from where you first notice oscillation
Signs of too high: Fine vibration, motor-like buzz in servos Signs of too low: Craft drifts, feels loose
3. Ferocity P — Crispness
Goal: Responsive but not twitchy.
Method: - Start at 15 - Bump the roll stick — does the craft immediately bite? - Increase until stick response is crisp - Back off if you see overshoot
Signs of too high: Ringing after stick input, bounce-back Signs of too low: Mushy, delayed response
4. Balance — Asymmetry Tuning
Goal: Equal authority in both directions.
Method: - Fly straight and level - Roll left, note response speed - Roll right, note response speed - Adjust balance to equalize them
5–7. Warp, Anchor, Resonance
Fine-tuning parameters. Only adjust after 1-4 are solid.
| Param | Start | Adjust When |
|---|---|---|
| Warp | 50 | Modulation feels too spread out or too peaky |
| Anchor | 70 | Want more/less raw PID mixed in |
| Resonance | 30 | Hovering unstable, or forward flight feels ringy |
8. Phase 2 — Advanced
| Param | Effect |
|---|---|
| Prescience | Timing advance — higher = modulation leads phase more |
| Espelho | Differential coupling — tighter roll, may reduce efficiency |
| Saudade | Stroke memory — smoother but less responsive |
| SSFF | Direct gyro→wave injection — start at 10 |
The goal is a craft that flies like it wants to be in the air. If you’re fighting it, back off and retune from Cadence up.
