# Understanding Betaflight Rates: RC Rate, Super Rate, and Expo Explained
Your rates determine how your quad responds to stick input. Too slow and you can’t flip out of trouble. Too fast and your HD footage looks like a washing machine. Understanding the three components — RC Rate, Super Rate, and Expo — is the difference between a quad that fights you and one that reads your mind.
## The Three Rate Components
Betaflight uses a three-variable system to map your stick position to rotational speed in degrees per second:
| Component | What It Controls | Range | Effect |
|———–|—————–|——-|——–|
| RC Rate | Linear sensitivity of the entire stick range | 0.50 – 2.50 | Higher = faster rotation at every stick position |
| Super Rate | Exponential boost near stick endpoints | 0.00 – 1.00 | Higher = aggressive snap at full deflection |
| Expo | Center-stick softening | 0.00 – 1.00 | Higher = gentler response near center, more precise hovering |
**The formula in Betaflight:**
`Actual Rate = (RC Rate × Stick Input) + (Super Rate × Stick Input³)`
Expo reshapes the curve without changing max rotation speed. Super Rate adds rotation *only* near the edges of the stick. RC Rate shifts the entire curve up or down.
## Recommended Rates by Flying Style
Here are battle-tested starting points. Adjust to your personal feel:
| Style | RC Rate | Super Rate | Expo | Max Deg/s | Who Uses It |
|——-|———|————|——|———–|————-|
| Cinematic / Cruising | 1.00 | 0.65 | 0.40 | ~450°/s | Smooth footage, gentle lines |
| Freestyle (Beginner) | 1.20 | 0.70 | 0.25 | ~650°/s | Controlled flips with recovery room |
| Freestyle (Advanced) | 1.40 | 0.75 | 0.15 | ~850°/s | Fast snaps, Matty flips, tight gaps |
| Racing | 1.60 | 0.78 | 0.10 | ~1000°/s | Maximum agility, instant direction change |
| Whoop / Indoor | 1.00 | 0.70 | 0.50 | ~550°/s | Precise angle-mode control |
**The Vanover approach (pro racer):** Low RC Rate (~0.80), very high Super Rate (~0.85), zero Expo. This gives you a docile center for straight-line speed but violent snap at the corners for hairpin turns.
**The Steele approach (freestyle):** Higher RC Rate (~1.50), moderate Super Rate (~0.72), and just enough Expo (~0.15) to avoid twitchiness during slow proximity moves.
## Common Rate Mistakes and Their Symptoms
| Symptom | Likely Cause | Fix |
|———|————-|—–|
| Quad feels “drunk” or delayed | RC Rate too low | Increase RC Rate by 0.10 increments |
| Overshooting flips / bouncing back | Super Rate too high | Reduce Super Rate or increase Expo |
| Can’t hold steady hover | Expo too low | Increase Expo to 0.30-0.50 |
| Feels like a “brick” near center | Expo too high | Reduce Expo to 0.10-0.20 |
| Flips are too slow to complete | Max deg/s too low | Increase Super Rate or RC Rate |
| Shaky HD footage | Rates too aggressive | Lower all three values across Pitch/Roll |
## Setting Rates in Betaflight
1. Open Betaflight Configurator → **PID Tuning** tab.
2. Scroll to the **Rates** section.
3. You’ll see three rows: Roll, Pitch, and Yaw. Each has independent RC Rate, Super Rate, and Expo sliders.
4. The graph on the right shows your actual rate curve. The X-axis is stick position, the Y-axis is degrees/second.
5. Use the dropdown to switch between **Actual** (Betaflight 4.4+) and **Betaflight** (legacy) rate types.
### Should Roll, Pitch, and Yaw Be Different?
Most pilots use the same rates for Roll and Pitch (symmetric flips feel natural), but Yaw should be faster:
| Axis | RC Rate | Super Rate | Expo | Reason |
|——|———|————|——|——–|
| Roll | 1.30 | 0.72 | 0.20 | Matched with pitch for symmetric acro |
| Pitch | 1.30 | 0.72 | 0.20 | Same as roll for consistent feel |
| Yaw | 1.50 | 0.75 | 0.10 | Faster yaw prevents “tank turret” feeling |
## How to Find Your Personal Rates
Don’t just copy someone else’s numbers. Find what works for **you**:
1. **Start with a known profile**: Try the “Freestyle Beginner” numbers above.
2. **Fly 3 packs without changing anything**. Your brain needs time to adapt.
3. **Tune one variable at a time**: Change only RC Rate by 0.10, fly 2 packs, evaluate. Then Super Rate. Then Expo.
4. **The “two-flip test”**: Go level at medium speed, pull full back on pitch. Count the flips before you exit:
– 1.5 flips? Rates are too slow. Increase Super Rate.
– 3+ flips? Rates are too fast. Reduce RC Rate or Super Rate.
– 2 clean flips with a smooth exit? Just right.
### Rate Profile Switching
Betaflight supports up to 6 rate profiles. Set up 3 profiles with different rates and switch between them using stick commands or a radio switch:
1. In the PID Tuning tab, select `Rateprofile 1`, set your main rates.
2. Switch to `Rateprofile 2`, set a faster profile for racing.
3. Switch to `Rateprofile 3`, set a cinematic profile for smooth footage.
4. In the Adjustments tab, assign a switch to change rate profiles mid-flight.
5. Toggle between profiles in the air to instantly compare feels.
## Rates for Specific Maneuvers
| Maneuver | Rate Tip |
|———-|———-|
| Matty Flip | High pitch rate (800+ deg/s) for quick inversion. Yaw can be lower. |
| Power Loop | Moderate pitch, higher yaw for corkscrew exits. |
| Juicy Flick | Maximum roll rate (900+ deg/s) with low Expo for instant direction reversal. |
| Rubik’s Cube | High yaw rate (800+ deg/s). This trick lives and dies on yaw speed. |
| Trippy Spin | High roll rate with moderate pitch. Smooth yaw prevents dizziness. |
| Long Range Cruising | Low rates all around. Batt voltage matters more than flip speed. |
## The Most Important Rule
**The best rates are the ones you never think about.** If you’re conscious of your rates during a flight — fighting over-correction or waiting for flips to complete — they’re wrong. When your rates are dialled in, stick movement translates to quad movement transparently, and you can focus entirely on line choice and trick execution.
