Curves

The Curves tab holds two independent pools of up to 8 reusable curves each. You edit a curve here, then assign it by number wherever it's used -- a Mixer rule, or a Profiles axis -- rather than defining the shape inline there. That reuse is the point: editing curve 3 here updates every rule or axis currently assigned to curve 3, so one curve can shape several things identically at once.

Mixer Curves

X: the mixer rule's input value. Y: the value substituted in its place once weighted onto the output. Both share the rule's own -1000..1000 scale. The default is a straight diagonal -- input passes straight through unchanged -- so there's nothing to assign until you deliberately bend it: more resolution near center, a dead zone, an asymmetric response, a non-linear throttle-to-motor curve, and so on. Assign one to a rule from the Mixer tab.

Gain Curves

X: stick deflection, 0% (centered) to 100% (full throw) -- the same curve applies in both directions, it doesn't distinguish left from right. Y: a gain multiplier, 0-500%, where 100% means no change. The gain actually applied in flight is Master Gain (set per-axis on Profiles) multiplied by this curve's value at the current stick position -- so a flat line at 100% has no effect at all. Drag a point below 100 to taper gain out as the stick moves that way (a softer response out toward the ends of the stick), or above 100 to sharpen it there.

Editing a curve

• Drag a point to move it, click empty plot space to add one, or right-click a point to remove it -- or use the point table alongside the plot for exact numeric values. Mixer curves allow up to 9 points; Gain curves up to 6.
• The first and last point are pinned to the curve's domain extremes (-1000/1000 for Mixer, 0%/100% for Gain) and can't be deleted or dragged in X, only Y -- they define where the curve starts and ends, so at least two points always exist and always span the full range.
• Reset Curve returns the currently selected slot to a neutral straight line (no reshaping, no gain change).
