  • ✅ 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

  1. No Altitude Hold

    • Mobula8 + Betaflight does not have barometer/alt-hold.
    • Throttle is fully manual: up = climb, down = descend.
  2. Throttle Center

    • Hover point is usually not at 50%.
    • For Mobula8 (2S), hover is often around 30–40% throttle.
  3. Tiny Quad Sensitivity

    • Small quads react fast to throttle changes.
    • Even small stick movement = big altitude change.

🛠️ How to Make Hovering Easier

  1. 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.

  1. 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.

  1. Set Proper Motor Idle

Betaflight → Configuration Tab.

Motor Idle Throttle Value: ~5% (default too low/high can cause jumps).

  1. 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
