108
+### 🚁 Why Throttle Feels Jumpy on Mobula8
109
+
110
+1. **No Altitude Hold**
111
+ - Mobula8 + Betaflight does not have barometer/alt-hold.
112
+ - Throttle is fully manual: up = climb, down = descend.
113
+
114
+2. **Throttle Center**
115
+ - Hover point is usually not at 50%.
116
+ - For Mobula8 (2S), hover is often around **30–40% throttle**.
117
+
118
+3. **Tiny Quad Sensitivity**
119
+ - Small quads react fast to throttle changes.
120
+ - Even small stick movement = big altitude change.
121
+
122
+
123
+### 🛠️ How to Make Hovering Easier
124
+
125
+1. Enable Angle Mode
126
+
127
+Betaflight Configurator → Modes Tab.
128
+
129
+Add ANGLE mode to a switch on your Radiomaster Pocket.
130
+
131
+Angle mode keeps the quad level so you only need to manage throttle.
132
+
133
+2. Adjust Throttle Curve / Expo
134
+
135
+On Radiomaster Pocket (EdgeTX):
136
+
137
+Go to Model Setup → Inputs → Throttle.
138
+
139
+Add Expo (20–30%) or a custom curve.
140
+
141
+This makes mid-throttle less sensitive, easier to hover.
142
+
143
+3. Set Proper Motor Idle
144
+
145
+Betaflight → Configuration Tab.
146
+
147
+Motor Idle Throttle Value: ~5% (default too low/high can cause jumps).
148
+
149
+4. Practice Hover
150
+
151
+Hover indoors at waist height.
152
+
153
+Slowly adjust throttle until you find the "sweet spot".
154
+
155
+Remember: FPV drones require constant micro-adjustments.

158
+## Best Preset Build for Mobula8 — Tuning Overview
159
+
160
+### 1. Base Tune (Factory Defaults)
161
+- Stick with the **factory PID and rates** unless you fly aggressively past stock performance.
162
+ - Many experienced pilots, including reviewers, report that “the default PIDs and rates felt dialed” for smooth flight :contentReference[oaicite:0]{index=0}.
163
+
164
+---
165
+
166
+### 2. Recommended Flight Modes
167
+- **Angle Mode** for stable, slow, and cinematic flight.
168
+- Optional: **Motor Beacon** (helps find your quad when disarmed) :contentReference[oaicite:1]{index=1}.
169
+
170
+---
171
+
172
+### 3. Essential Configuration Settings
173
+- **Configuration →**
174
+ - **Arming Angle**: Set to **180** to allow arming from uneven ground
175
+ - **Thrust Linearization**: Useful for smooth low-throttle response; a small boost (~20%) helps
176
+
177
+---
178
+
179
+### 4. PID Adjustments (Optional, For Smoother Flight)
180
+If you want even smoother, gentle flight:
181
+- On Mobula6 users reported:
182
+ - **Roll / Pitch** P: ~18–20
183
+ - **I**: 30
184
+ - **Feedforward / Damping tweaks** apply similarly well to Mobula8
185
+
186
+---
187
+
188
+### 5. Rate Settings for Smooth Control
189
+- Custom builds often use **higher rates** (e.g. roll & pitch ~850, yaw ~700) with expo to mellow control lines :contentReference[oaicite:5]{index=5}.
190
+- Adjust RC Expo to around **0.5** for soft response at stick center (common for smooth flight profiles).
191
+
192
+---
193
+
194
+### 6. Filtering and RPM Output
195
+- 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}.
196
+- Stick with **DSHOT300 or 600**, add some **RPM filtering** if your ESC supports it :contentReference[oaicite:7]{index=7}.
197
+

208
+| Optional PID tweak | P ≈ 18–20, I = 30 for gentle flight |
