Swashplate Mixing - Spektrum DX7 Instruction Manual

Swashplate Mixing

The Swashplate Mix screen is only displayed when a CCPM swashplate mix is activated. (See page 80 for
Swashplate Type to enable Swashplate Mix.) Swashplate Mix adjusts the amount and direction of travel, for
the aileron, elevator and pitch functions. For example, if more aileron travel is desired, increasing the aileron
swashplate mix value will increase the overall travel of the servos necessary to achieve greater aileron throw.
Note: Negative values are available which will reverse the direction of that function.

Note: Selecting a negative value will reverse the direction of the function.
Note: A swashplate Exponential function is available that compensates for the non-linear output
caused by the rotation of the cyclic servos. This EXP function eliminates swashplate interactions
at the extremes of travel. It is recommended that the EXP function be activated at all times.

Throttle Hold
The Throttle Hold function is used to practice autorotation and is often used as a safety switch for electric
helicopters, holding the throttle in the off position. When the throttle hold switch is activated, the throttle hold
function holds the throttle servo/ ESC in a specific position (normally low or off throttle) while all other servos
function normally. The throttle hold switch is also selectable. Switch selection options include rudd D/R, gear,
AUX 2, aileron D/R or elevator D/R.
