Angle — the stick sets the tilt angle (up to 55°); release it and the drone levels itself. Horizon — like Angle near the stick centre, like Acro at full deflection: flips and rolls are possible. Acro — the stick sets the rotation rate; the drone never levels itself.
Throttle is absolute in every mode: about 40 % hovers when level (see the Drone tab).
On a gamepad the throttle stick centre is 0 % and full up is 100 % — release the stick and the drone falls.
W
Throttle rises while held (+100 % per second); released — 0 %, the drone falls. Tap it to hover.

Betaflight "Actual" rates: Center Sensitivity — °/s slope around the stick centre (fine control),
Max Rate — °/s at full stick, Expo — how long the curve stays flat before rising to the max.
Rates drive Acro, and Horizon near full stick; Angle uses the 55° angle limit instead (yaw always uses rates).
Dots on the graph show the current stick positions.
The flight model uses these numbers: thrust grows with throttle² and with the battery voltage²,
the current comes from the motor efficiency, and the pack voltage sags with the current and falls as it empties.

Thrust and efficiency are the manufacturer's claims. Editing comes later.
