Rate Presets — 733 / 633 / 533 in Betaflight & Actual
533, 633, 733 are community shorthand for three popular freestyle rate profiles, and the number is the maximum rotation rate in °/s — 733 tops out around 730 °/s, 533 around 530 °/s. They're all built the same way in the legacy Betaflight system: a fixed Super Rate 0.70 with the RC Rate stepped up. This snippet gives each in both rate systems (legacy Betaflight and Actual) with copy-paste CLI and the real curve. For the formulas behind the systems see Rate Modes; for the center/mid/edge zones see the Rates Deep Dive.
Why the number is the max rate
In the legacy Betaflight system the ceiling at full stick is:
1maxRate = 200 × RC Rate / (1 − Super Rate)
With Super Rate fixed at 0.70, the denominator is 0.30, so maxRate = 666.7 × RC Rate:
| Profile | RC Rate | Super Rate | 200 × RC ÷ (1 − SR) | Max rate |
|---|---|---|---|---|
| 533 | 0.80 | 0.70 | 200 × 0.80 ÷ 0.30 | 533 °/s |
| 633 | 0.95 | 0.70 | 200 × 0.95 ÷ 0.30 | 633 °/s |
| 733 | 1.10 | 0.70 | 200 × 1.10 ÷ 0.30 | 733 °/s |
Raising RC Rate lifts the whole curve (and the ceiling); the shared Super Rate 0.70 gives them the same "soft-ish center, hard edge" shape. Expo is not part of the shorthand — it's a personal add-on (commonly 0.10–0.20) that softens the center without changing the max.
These are honest freestyle rates. For reference: racing tends to run flatter ~550–650 °/s, general freestyle ~650–900 °/s, and aggressive/pro freestyle 900–1200 °/s.
533is the mellow end,733is solidly punchy.
At a glance
| Profile | Feel | Legacy BF (RC · SR · Expo) | Actual (center / max / expo) | Max rate | Use case |
|---|---|---|---|---|---|
| 733 | Punchy, fast flips | 1.10 · 0.70 · 0 | 220 / 730 / 55 | ~733 °/s | Confident freestyle, snappy tricks |
| 633 | Balanced all-rounder | 0.95 · 0.70 · 0 | 190 / 630 / 55 | ~633 °/s | General freestyle / cruising |
| 533 | Mellow, smooth, linear | 0.80 · 0.70 · 0 | 160 / 530 / 54 | ~533 °/s | Learning acro, racing lines, cine |
The Actual columns reproduce the same curves to within ~0.5 % (verified against Betaflight's applyBetaflightRates / applyActualRates).
The three curves
Same shape, three heights. Super Rate 0.70 keeps the first ~60 % of stick relatively tame, then the curve ramps hard toward full deflection — that's where the "snap" for flips and rolls lives. Higher RC Rate raises both the center liveliness and the ceiling.
733 — punchy
Center sensitivity ~220 °/s and a ceiling of ~733 °/s. Full-stick flips and rolls come around fast, while the Super-Rate curve keeps mid-stick manageable for line work. A common "I can actually freestyle now" profile. Aggressive pilots push RC Rate higher still (833/933+).

633 — balanced
Center sensitivity ~190 °/s, max ~633 °/s. The middle-ground freestyle profile — responsive enough for tricks, calm enough for long cruising lines. A great default while you decide whether you want more (733) or less (533).

533 — mellow
Center sensitivity ~160 °/s, max ~533 °/s. The gentlest of the three: slower rotations and a calmer center make it forgiving for learning acro, and its flatter feel suits racing-style lines and smooth cinematic flying. Still a real freestyle rate, just relaxed.

Legacy and Actual describe the same curve
Both rate systems store into the same CLI fields (rc_rate, srate, expo) — rates_type just changes how those numbers are interpreted:
| Field | Legacy Betaflight | Actual |
|---|---|---|
rc_rate | RC Rate × 100 (a multiplier) | Center sensitivity ÷ 10 (°/s) |
srate | Super Rate × 100 | Max rate ÷ 10 (°/s) |
expo | Expo × 100 | Expo × 100 (shifts the kink) |
Because the underlying math differs, the expo numbers are not the same between systems even for an identical curve — that's why 733's expo=0 in legacy becomes expo=55 in Actual (the Actual expo recreates the shape that Super Rate produces in the legacy model). The curves themselves overlap:
Notes
- Expo is not part of the shorthand. Add
expo(0.10–0.20 legacy, ~30–50 in Actual) to soften the center for finer hover/line control — it does not change the max rate. - Yaw is shown equal to roll/pitch for clean copy-paste. Many pilots drop yaw slightly for cleaner spins — lower the
yaw_*values to taste. - After pasting, open the Rates tab in Betaflight Configurator and confirm the live curve and the max-rate readout match the table above before flying.
- Switching
rates_typedoes not erase the other system's values — Betaflight keeps them per profile, so you can flip between BETAFLIGHT and ACTUAL to compare.
