Camber System; Sail Mixing; Differential - Spectrum DX8 Instruction Manual

Camber System

Camber System is only available when 2 aileron wing type is selected in Wing Type. The Camber System allows in-flight camber
adjustment and is also used as the braking system, often referred to as Crow or Butterfly. The Camber System enables you to
assign the Camber System to the Spoiler Stick, right or left trimers or the Right Knob for each flight mode.

SAIL Mixing

For each of these mixes, you can program each flight mode with different mix values or at 0% if no mix is desired for that specific flight mode.
Programming values include independent control of the direction and the amount a slave surface moves in relationship to the master surface.
Aileron to Rudder
The Aileron to Rudder mix is a commonly used for coordinated turns. When active, as aileron is applied the rudder moves in the same
direction as the turn (right aileron input results in right rudder output).
Aileron to Flap
The Aileron to Flap mix allows the entire trailing edge of the wing (aileron
as ailerons. When active, as aileron is applied the flaps also move.
flaps to move in the same direction as the turn (so that right aileron is
moving as right ailerons).
Elevator to Flap
Elevator to Flap mix creates more lift, allowing a tighter turn by applying
elevator. An offset is provided which is typically used for Snap Flaps.
Elevator to Flap mix occurs until the offset value is reached. Typically
up elevator so that beyond 70% the down flap mix comes in, providing
more aggressive turning (for tight thermals or racing turns).
Flap to Elevator
Flap to Elevator mix prevents pitch up tendency that occurs when brakes
are applied. This mix is typically used only with the brake system (See
This mix operates as a curve, so that the elevator typically moves down
20% of flap deployment, decreases over the next 40% then remains the
100% of flap travel.

Differential

The Differential function decreases the amount an aileron moves down
without affecting the amount the other aileron moves up. This can
decrease adverse yaw (right or left movement of the aircraft nose)
tendencies during roll maneuvers. Positive (+) and negative (-)
differential is available; however, normally more up (+) aileron travel is
required than down (-). Assign a switch to enable differential values
flight or select "On" so that differential is always enabled.
