4. Use OSD to adjust VTX which displays information like battery voltage and mAh consumed while you fly. In addition, the beta flight OSD can be used to configure the quadcopter, making in-field adjustments and tuning more convenient

The graphics above show the stick command to bring up the OSD menu. The stick commands throttle centered, yaw left, pitch forward. The exact stick command, therefore, depends on which mode your transmitter sticks are in. In the OSD menu, use pitch up/down to move the cursor between menu items. When a menu option has a > symbol to the right of it, this indicates that it contains a sub-menu. Roll-right will enter the sub-menu. For example, in the screen to the right, moving the cursor to “Features” and then moving the roll stick to the right will enter the “Features” sub-menu.

To adjust PIDs, rates, and other tuning-related parameters, enter the “Profile” sub-menu. In the “Scr Layout” sub-menu, you can move the OSD elements (like battery voltage, mAh, and so forth) around on the screen.

The “Alarms” sub-menu lets you control when the OSD will try to alert you that battery voltage is too low or mAh consumed is too high. When a parameter can be modified, the parameter’s current value will be shown on the right-hand side of the screen. In this case, roll left/right will adjust the parameter up and down. The screen to the right shows the current vTX settings. From here, you can change the frequency band, channel, and power level of the video transmitter. After making the changes, move the cursor to “Set” and press roll-right to confirm the settings.
