Rates are the single most personal setting on your quad. Two pilots with identical hardware, identical PIDs, and identical batteries can have completely different experiences because they fly different rates. Yet most pilots copy a YouTuber’s rates, fly them for a year, and never question whether they actually match their flying style. This guide breaks down every rate parameter, shows you what each one actually does to your quad’s rotational behavior, and gives you a methodical way to find rates that feel like an extension of your thumbs — not a compromise.
RC Rate, Super Rate, and Expo: What Each Parameter Does
Betaflight’s rate system uses three interacting parameters per axis (roll, pitch, yaw). Understanding them individually is essential before you can combine them effectively.
RC Rate
RC Rate is the base sensitivity. It determines the maximum rotational speed (in degrees per second) at full stick deflection — before Super Rate is applied. Think of it as the linear component: center stick through mid-stick, the quad rotates at an almost constant rate proportional to your stick position multiplied by RC Rate. A higher RC Rate makes the entire stick range feel more responsive at all deflection points.
Super Rate
Super Rate is nonlinear sensitivity that only kicks in at higher stick deflections. It is the “exponential on the top end” — at 50% stick, Super Rate has almost no effect. At 80% stick, it adds significant rotation speed. At 100% stick, it produces the maximum deg/s value that Betaflight reports as your “Max Rate.” Super Rate controls how much extra rotation speed you get when you push the stick to the corners, without making center-stick feel twitchy.
Expo
RC Expo flattens the response curve around center stick while compensating by steepening it near the edges. High expo (0.60–0.80) gives you a wide “dead-feeling” zone around center for precision, then accelerates rapidly past 60% deflection. Low expo (0.10–0.30) makes the stick response nearly linear — every millimeter of stick movement produces a proportional change in rotation speed.
| Parameter | Affects Center | Affects Max Rate | Typical Range |
|---|---|---|---|
| RC Rate | Moderate | Moderate | 0.80–1.80 |
| Super Rate | Minimal | High | 0.65–0.90 |
| RC Expo | High | Minimal | 0.10–0.75 |
Rate Types: Actual, Betaflight, Quick, Raceflight
Betaflight offers four math models for how the three parameters combine. Each produces a different stick-to-rotation curve:
- Actual Rates: Uses a single number — Center Sensitivity and Max Rate — with expo on a continuous curve. Entry: you set values of 20–200 (center) and 200–1200 (max). Most intuitive for new tuners.
- Betaflight Rates: The classic three-parameter system (RC Rate, Super Rate, Expo). Gives you the most granular control. Preferred by experienced tuners who want independent control over center feel and top-end speed.
- Quick Rates: Simplified Actual Rates with less configuration. Good for quick setup but limited fine-tuning.
- Raceflight Rates: Legacy system from Raceflight firmware. Seldom used in 2026; exists for backward compatibility.
For 90% of pilots, Actual Rates is the right choice — it is simpler to reason about and produces smooth, predictable curves. If you are chasing a very specific center-stick feel that Actual Rates cannot deliver, switch to Betaflight Rates.
Center Sensitivity vs Maximum Rotational Speed
The core tradeoff in rate tuning: center sensitivity (how much the quad rotates for a small stick input) versus maximum rotational speed (how fast it flips at full stick). A quad with 900 deg/s max rate and high center sensitivity will feel twitchy and hard to fly smoothly. The same 900 deg/s with low center sensitivity and high super rate will feel locked-in at center but explosive at the corners — ideal for freestyle.
In Actual Rates, center sensitivity values translate roughly to:
- 10–30: Extremely soft center — cinematic and beginner-friendly
- 40–70: Balanced center — good for all-around flying
- 80–150: Aggressive center — racing and quick-reaction freestyle
- 150+: Unstable for most pilots — requires extremely precise stick control
Recommended Starting Rates by Flying Style
| Style | Roll Rate | Pitch Rate | Yaw Rate | Center Sensitivity | Expo |
|---|---|---|---|---|---|
| Racing | 550–700 | 500–650 | 550–700 | 80–120 | 0.15–0.30 |
| Freestyle | 750–900 | 700–850 | 650–800 | 50–80 | 0.30–0.50 |
| Cinematic | 300–500 | 250–450 | 300–500 | 15–40 | 0.40–0.70 |
| Beginner | 400–600 | 350–550 | 400–600 | 30–50 | 0.50–0.70 |
These are starting points — not final values. Use them to get airborne, then tune.
How to Find Your Personal Rates
The “copy a pro” method does not work because that pro has spent hundreds of hours adapting their muscle memory to those specific rates. Instead, use a gradual testing process:
- Set all three axes to a known-safe baseline (e.g., Actual Rates: Roll 600/60, Pitch 550/55, Yaw 600/60). Fly 3–4 packs.
- Change one axis by 50–70 deg/s. Fly 3 more packs. Ask yourself: did flips feel too slow? Did rolls overshoot? Is yaw predictable?
- Adjust center sensitivity independently from max rate. If full-stick flips feel right but center-stick precision is lacking, change only center sensitivity.
- Repeat for each axis over multiple sessions. Write down the numbers you tried and one sentence about how each felt. After 10–15 packs across 3–4 sessions, you will have converged on your personal rates.
- Save your final rates as a Rateprofile. Create a second Rateprofile with slightly lower rates for tight courses or new locations.
Throttle Curves, Throttle Expo, and Throttle Mid
Rates control rotation — throttle controls altitude. The two interact: you cannot fly smoothly if your throttle response is fighting your rate response.
Throttle Mid
Throttle mid (default 0.50) sets the stick position at which the quad hovers. Raise it (0.60–0.75) if your quad feels like it “jumps” off the ground at 25% throttle. Lower it (0.25–0.40) for high-power builds where 30% throttle is already climbing fast. The correct throttle mid makes the hover point sit naturally at 50% stick — this is the foundation of good throttle control.
Throttle Expo
Throttle expo (0.00–1.00) flattens the throttle curve around the hover point. At 0.50 expo, the throttle response around mid-stick is noticeably softer, giving you finer altitude control. At 0.00, throttle is perfectly linear. Freestyle pilots typically run 0.30–0.50 expo for smooth altitude transitions during tricks. Racers often run 0.00–0.20 for instant throttle response.
Throttle Limit
Throttle limit scales the maximum output — useful for limiting a 6S quad to 4S-equivalent power, or protecting fragile cinewhoop ducts from melting at full throttle. Set as a percentage (e.g., 85% throttle limit means the FC never outputs more than 85% to the ESCs). Combine with a throttle cut type of “Scale” (default) for consistent feel across the range.
Yaw Rates: The Overlooked Axis
Yaw is physically different from roll and pitch. Your quad yaws by varying motor torque differential, not by tilting the thrust vector. This makes yaw inherently slower and less precise than roll/pitch. Many pilots set yaw rates too high (matching roll), then fight yaw overshoot on every sharp turn.
A good rule: set yaw max rate 50–100 deg/s lower than roll. If your roll is 800 deg/s, try yaw at 700–750 deg/s. Additionally, yaw benefits from slightly lower center sensitivity than roll — yaw oscillations are harder to damp out with PID tuning alone.
How Rates Interact with PID Tuning
Rates and PIDs are coupled: higher rates demand faster PID response because the quad changes attitude more rapidly. If you increase your roll rate from 600 to 900 deg/s, your PIDs that worked perfectly at 600 may produce overshoot or bounce-back at 900. After a significant rate change, fly a few aggressive snap rolls and check for bounce on the stop. If you see bounce, increase D gain on that axis by 3–5 points. This is not a PID problem — it is a rate change exposing a PID that was tuned for slower rotation speeds.
Stick Time and Transition Sharpness
Stick time (or “transition” in the rate settings) controls how quickly the quad accelerates toward the commanded rotation rate. Lower stick time (0.05–0.10) makes the quad snap into flips instantly — preferred by racers. Higher stick time (0.15–0.30) smooths the transition, making flips look more cinematic. This is separate from feedforward — stick time affects the setpoint, feedforward affects how hard the PID loop chases it.
Final advice: stop changing your rates every week. Find something that works, fly it for a month, and let your muscle memory build. The best rates are the ones you do not think about in the air.
