 +==== Control Grouping ====
 +
 +VSPAERO allows for trimming of the vehicle’s control surface deflections by defining control surface groups in the the VSPAERO setup file. This is facilitated by the Control Grouping tab of the VSPAERO GUI. The middle browser labeled “Available Control Surfaces” lists all rectangle and control surface sub-surfaces that can be added to a control surface group. They are named using the following convention: “GeomName_SurfaceName_Sub-SurfaceName”. If no control surface groups have been created, the middle browser will be empty. A control surface group is created by clicking the “Add” button under the left-most browser labeled “User Groups”. The group can then be renamed using the “Group Name” input. The desired control surfaces can be added to the group using the “Add Selected” or “Add All” buttons under the middle browser, moving them over to the right-most browser labeled “Grouped Control Surfaces”. A control surface can only be added to a group once, but a control surface can be added to multiple groups. When selected within a particular group, available control surfaces will be highlighted in red and those already added to the group will be highlighted in green. In addition, the button labeled “Auto Group Remaining Control Surfaces” will define control surface groups for all symmetric control surfaces still available. ​
 +
 +When a control group is selected, each control surface in the group will appear under the “Deflection Gains per Surface” divider. Here, the gains can be adjusted to allow for mixing of control surfaces within a group. For example, asymmetric aileron deflection or symmetric flap deflection. Note, the default value for all gains is 1, which will cause an asymmetric load distribution for a symmetric control surface group. On the Overview tab of the GUI, all control groups will be listed under the “Control Group Angles” divider. Each control group will have a toggle next to its name that determines if the group should be included in the VSPAERO run. If the toggle is selected, the deflection angle for the entire control group can be specified. ​
