# Vehicle (Frame) Selection
After installing firmware you need to select the vehicle type and specific frame configuration that best matches your vehicle frame. This applies appropriate default parameter values for the selected frame, such as the vehicle type, number of motors, relative motor position, and so on.
注解
Choose the frame that matches your vehicle brand and model if one exists, and otherwise select the closest "Generic" frame option matching your vehicle.
# Set the Frame
To set the airframe:
Start QGroundControl and connect the vehicle.
Select "Q" icon > Vehicle Setup > Airframe (sidebar) to open Airframe Setup.
先选择你的机架符合的大致分类，然后在下拉菜单中选择最匹配的机架类型。
The example above shows Generic Hexarotor X geometry selected from the Hexarotor X group.
Click Apply and Restart. Click Apply in the following prompt to save the settings and restart the vehicle.
