60
-- General setting that shifts the "zero level" of the accelerometer.

67
-- Adjusts the accelerometer’s idea of "level" on the **Roll axis** (left ↔ right).

69
- - Drone drifts **right** in Angle Mode → add **positive Roll Trim**.

-### What is Air Mode?
249
-- Air Mode is a **Betaflight flight feature** that keeps the motors active and responsive even at **zero throttle**.
250
-- Without Air Mode:
251
- - When you cut throttle, motors almost stop spinning.
252
- - The quad loses control authority and can "fall" or tumble.
253
-- With Air Mode ON:
254
- - Motors always maintain some thrust (idle speed).
255
- - You can still control pitch, roll, and yaw when throttle stick is at minimum.
256
-
257
-### Why Use Air Mode on Whoops?
258
-- ✅ Smoother hovering and stable control, even at low throttle.
259
-- ✅ Prevents sudden drop when you release throttle indoors.
260
-- ✅ Essential for flips, rolls, or freestyle tricks.
261
-- ⚠️ For very small **brushed whoops**, it can make them bounce indoors (too sensitive).

+#### 1. Accelerometer Trim
60
+- General setting that shifts the "zero level" of the accelerometer.
61
+- Used if your quad drifts in Angle/Horizon mode even after calibration.
62
+- Instead of recalibrating, you can apply a small trim value here.
63
+
64
+---
65
+
66
+#### 2. Accelerometer Roll Trim
67
+- Adjusts the accelerometer’s idea of "level" on the **Roll axis** (left ↔ right).
68
+- Example:
69
+ - Drone drifts **right** in Angle Mode → add **positive Roll Trim**.
70
+ - Drone drifts **left** → add **negative Roll Trim**.
71
+
72
+---
73
+
74
+#### 3. Accelerometer Pitch Trim
75
+- Adjusts the accelerometer’s "level" on the **Pitch axis** (forward ↔ backward).
76
+- Example:
77
+ - Drone drifts **forward** in Angle Mode → add **positive Pitch Trim**.
78
+ - Drone drifts **backward** → add **negative Pitch Trim**.
