betaflight-rateprofile-dat

  • Controls stick sensitivity and how fast the quad responds
  • Lower values = slower, smoother indoor control
  • Higher values = faster, more aggressive control

Lower RC Rate → overall slower stick response.

  • Roll: RC Rate 1.0 | Super Rate 0.65 | Expo 0.25
  • Pitch: RC Rate 1.0 | Super Rate 0.65 | Expo 0.25
  • Yaw: RC Rate 0.8 | Super Rate 0.70 | Expo 0.30
  • Throttle Mid: 0.30
  • Throttle Expo: 0.25

Rates Type == Actual

  • Center Sensitivity → how responsive the quad is around stick center.
  • Max Rate (deg/s) → maximum rotation speed at full stick deflection.
  • Expo → how much the curve softens near center stick.

1. Center Sensitivity

  • Controls responsiveness near stick center.
  • Indoor flying → set lower than outdoor to avoid twitchiness.
  • Example: Center Sensitivity = 120 (instead of 200+ for outdoors).

2. Max Rate

  • Sets the maximum rotation speed (°/s).
  • Indoor = keep rotation slower to avoid overshooting in tight spaces.
  • Example: Max Rate = 400–500°/s (outdoor freestyle often 700–1000°/s+).

3. Expo

  • Smooths stick center further while keeping full rate at stick ends.
  • Indoor = a bit more expo to help small corrections.
  • Example: Expo = 0.3–0.4.

  • Roll: Center Sensitivity = 120 | Max Rate = 450 | Expo = 0.35

  • Pitch: Center Sensitivity = 120 | Max Rate = 450 | Expo = 0.35
  • Yaw: Center Sensitivity = 100 | Max Rate = 400 | Expo = 0.30

RC Rate == Center Sensitivity

Rate RC == Max Rate == how many degree per second

Expo (Exponential) adjusts the sensitivity of your stick inputs around the center position.

  • Expo = 0: Stick response is linear—movements are directly proportional.
  • Higher Expo: Makes the center of the stick less sensitive (smoother, easier for small corrections), while the ends remain more responsive.

This helps pilots make precise, gentle movements without sacrificing full stick authority for fast maneuvers.

Throttle Limit Throttle Limit % Throttle MID Throttle EXPO
OFF 80 0.20 0.70

  1. Enable Throttle Expo:
    • Set Throttle Expo = 0.2–0.4.
    • Reduces sensitivity around mid-throttle.
  2. Adjust Throttle Mid:
    • If hover is at ~30% stick, set Throttle Mid = 0.3.
    • Matches your hover point with expo curve.

optimized version 2 for indoor flying

Throttle Limit Throttle Limit % Throttle MID Throttle EXPO
SCALE 55 0.5 0.5

Throttle Limit

  • Scale: reduces power evenly across whole range.
  • Clip: cuts off only top-end throttle.

TPA / TPA Breakpoint

  • TPA = smooths high-throttle behavior
  • Breakpoint = throttle point where TPA starts
  • Indoor: minimal effect, focus more on PID, Rates, and Throttle MID

hover == throttle mid

Throttle MID controls how stick input translates to motor power

  • Lower = more sensitive at low throttle
  • Higher = more stable at low throttle

Test Flight

  • Arm the quad, hover at mid-throttle
  • If drone rises too fast → increase Throttle MID slightly
  • If drone feels sluggish → decrease Throttle MID slightly
