Frame wheelbase: 85 mm (motor-to-motor diagonal)
- Typical prop size: 2 inches
-
Reason:
- 65 mm whoops → ~31 mm props (≈1.2 inch)
- 75 mm whoops → ~40 mm props (≈1.6 inch)
- 85 mm whoops → ~48 mm props (≈2 inch)
- 65 mm whoops → ~31 mm props (≈1.2 inch)

- ✅ 2S (7.4V LiPo / 8.7V LiHV) → Official recommended setup
- ⚠️ 3S (11.1V LiPo / 13.05V LiHV)
- Technically possible but NOT recommended with 11000KV motors
- Motors will run hot, risk of burning out
- Frame is very light → too much power, hard to control indoors
- ❌ 4S (14.8V LiPo / 17.4V LiHV)
- Not supported
- Will instantly overheat or fry ESC/motors
problems
🚁 Why Throttle Feels Jumpy on Mobula8
-
No Altitude Hold
- Mobula8 + Betaflight does not have barometer/alt-hold.
- Throttle is fully manual: up = climb, down = descend.
-
Throttle Center
- Hover point is usually not at 50%.
- For Mobula8 (2S), hover is often around 30–40% throttle.
-
Tiny Quad Sensitivity
- Small quads react fast to throttle changes.
- Even small stick movement = big altitude change.
🛠️ How to Make Hovering Easier
- Enable Angle Mode
Betaflight Configurator → Modes Tab.
Add ANGLE mode to a switch on your Radiomaster Pocket.
Angle mode keeps the quad level so you only need to manage throttle.
- Adjust Throttle Curve / Expo
On Radiomaster Pocket (EdgeTX):
Go to Model Setup → Inputs → Throttle.
Add Expo (20–30%) or a custom curve.
This makes mid-throttle less sensitive, easier to hover.
- Set Proper Motor Idle
Betaflight → Configuration Tab.
Motor Idle Throttle Value: ~5% (default too low/high can cause jumps).
- Practice Hover
Hover indoors at waist height.
Slowly adjust throttle until you find the "sweet spot".
Remember: FPV drones require constant micro-adjustments.
Best Preset Build for Mobula8 — Tuning Overview
1. Base Tune (Factory Defaults)
- Stick with the factory PID and rates unless you fly aggressively past stock performance.
- Many experienced pilots, including reviewers, report that “the default PIDs and rates felt dialed” for smooth flight :contentReference[oaicite:0]{index=0}.
2. Recommended Flight Modes
-
Angle Mode for stable, slow, and cinematic flight.
- Optional: Motor Beacon (helps find your quad when disarmed) :contentReference[oaicite:1]{index=1}.
3. Essential Configuration Settings
-
Configuration →
- Arming Angle: Set to 180 to allow arming from uneven ground
- Thrust Linearization: Useful for smooth low-throttle response; a small boost (~20%) helps
4. PID Adjustments (Optional, For Smoother Flight)
If you want even smoother, gentle flight:
- On Mobula6 users reported:
- Roll / Pitch P: ~18–20
- I: 30
- Feedforward / Damping tweaks apply similarly well to Mobula8
5. Rate Settings for Smooth Control
- Custom builds often use higher rates (e.g. roll & pitch ~850, yaw ~700) with expo to mellow control lines :contentReference[oaicite:5]{index=5}.
- Adjust RC Expo to around 0.5 for soft response at stick center (common for smooth flight profiles).
6. Filtering and RPM Output
- Many users dial down gyro/D-term filter multipliers (e.g., from 0.9 → 0.8 → 0.7) to reduce vibration and jello :contentReference[oaicite:6]{index=6}.
- Stick with DSHOT300 or 600, add some RPM filtering if your ESC supports it :contentReference[oaicite:7]{index=7}.
7. Preset Summary (In One Table)
| Feature | Recommendation |
|---|---|
| PID | Stock factory (default) |
| Flight Modes | Angle mode + Motor Beacon |
| Arming Angle | Max: 180° |
| Thrust Linear | ~20% boost for smooth low throttle |
| Optional PID tweak | P ≈ 18–20, I = 30 for gentle flight |
| Rates | Roll/Pitch ~850, Yaw ~700, Expo ~0.5 |
| Filtering | Gyro/D-term filter ~0.8 multiplier |
