Planned Features

Future features and enhancements for ArduDeck.

Rate Profile Switching (In-Flight)

Priority: P1 Complexity: Medium Target: Modes Wizard + Rates Tab

The Problem

Pilots often want different stick sensitivity for different situations:

  • Learning: Slow, forgiving response
  • Freestyle: Balanced, controlled but responsive
  • Racing: Fast, snappy response
  • Cinematic: Ultra-smooth for filming

Currently, rates are a single profile. Changing them requires landing and connecting to configurator.

Proposed Solution

Allow users to configure 2-3 rate profiles and switch between them in-flight using an AUX switch.

User Experience (Beginner-Focused)

Step 1: Choose Your Profiles

Which flying styles do you use?

[Smooth]          [Normal]           [Fast]
Turtle icon       Gauge icon         Rocket icon
"Slow & steady"   "Balanced feel"    "Snappy response"
Perfect for       Good for most      For experienced
filming           flying             pilots

Step 2: Assign a Switch

Which switch should change your rates?

[Switch A]  [Switch B]  [Switch C]  [Switch D]
   AUX1        AUX2        AUX3        AUX4

Tip: Use a 3-position switch for 3 profiles,
     or a 2-position switch for 2 profiles.

Step 3: Test It

Flip your switch to see which profile activates:

[====|====|====]  <- Switch position indicator
 LOW   MID  HIGH

Current: [SMOOTH] - Slow, cinematic movements
         Rate curve visualization showing gentle curve

Technical Implementation

MSP Commands

iNav:

  • rateprofile <0-2> via CLI to select active profile
  • MSP2 0x2007/0x2008 for read/write rates
  • Adjustment function for in-flight switching (needs research)

Betaflight:

  • MSP_SET_ADJUSTMENT_RANGE for AUX-based profile switching
  • Adjustment ID for rate profile selection
  • Multiple rate profiles supported natively

Store Structure

interface RateProfileState {
  // Profile data
  profiles: RateProfile[];        // 2-3 profiles
  activeProfileIndex: number;     // Currently selected

  // Switch assignment
  auxChannel: number;             // Which AUX controls switching
  switchPositions: number[];      // PWM ranges for each profile

  // Live preview
  rcChannels: number[];           // For showing active profile

  // Presets
  presets: RatePreset[];          // Smooth, Normal, Fast, etc.
}

interface RateProfile {
  id: string;
  name: string;                   // "Smooth", "Normal", "Fast"
  icon: LucideIcon;
  description: string;
  rates: RatesConfig;
}

UI Components

  1. RateProfileWizard - Step-by-step setup (in Modes Wizard or standalone)
  2. RateProfileSelector - Quick switcher in Rates Tab header
  3. RateProfileCard - Visual card showing profile with rate curve
  4. RateCurvePreview - Live visualization of rate response

Beginner-Friendly Presets

Preset Roll/Pitch Rate Expo Feel
Smooth 200 40 Slow, cinematic, very forgiving
Normal 400 25 Balanced, good for most flying
Freestyle 600 15 Responsive, good for tricks
Racing 800 5 Fast, linear, snappy

Copy/Text Guidelines

  • "Smooth" not "Low rates with high expo"
  • "How fast your drone spins" not "Angular velocity"
  • "Flip your switch" not "Change AUX channel PWM value"
  • Show the feel, not the numbers

Files to Modify

File Changes
stores/rate-profile-store.ts New store for profile state
MspConfigView.tsx Add profile selector to RatesTab
msp-handlers.ts Add profile switching MSP calls
modes-wizard-store.ts Optional: integrate with modes wizard
rate-presets.ts New file for beginner presets

Open Questions

  1. Does iNav support adjustment functions for rate profile switching?
  2. Should this be part of Modes Wizard or a separate Rates Wizard?
  3. How many profiles to support? (2 vs 3)
  4. Should we show rate curves or simplified "feel" indicators?
