Setting up camera tilt adjustment during flight requires connecting your camera tilt servo to an available motor output on your flight controller and configuring it through your FC's software. Most modern flight controllers running Betaflight, INAV, or similar firmware have multiple output pads that can serve dual purposes.
First, physically connect your servo signal wire to an unused motor output pad on your flight controller. Most racing quads use motors 1 through 4, leaving outputs 5 through 8 available. A typical camera tilt servo draws minimal current, so you can power it directly from your flight controller's 5V BEC pad. Connect the servo's positive wire to a 5V pad, ground to a GND pad, and signal wire to something like motor output 5.
Now comes the configuration part. Open Betaflight Configurator and navigate to the Servos tab. You'll see a list of servo outputs corresponding to your motor outputs. Enable the servo channel you've connected to, typically S5 if you used motor output 5. Set the minimum value to around 1000 and maximum to 2000 as starting points. These values represent microseconds of PWM signal, and you may need to adjust them based on your servo's range to avoid binding.
Next, head to the Modes tab or Configuration tab depending on your firmware version. You need to link this servo output to a channel from your receiver. Most pilots use a three-position switch or a potentiometer knob on their transmitter. In your radio transmitter settings, assign an unused AUX channel to your preferred switch. For example, if you're using AUX3, configure your transmitter so that switch SA controls AUX3 with different values for each position.
Back in Betaflight, you'll map this AUX channel to the servo output. In the CLI, you can use the command "servo 4 1004 2006 1500 100 -1" where the numbers represent your connected channel. The rate value controls how much the servo moves relative to stick input.
Test everything on the bench first. Move your transmitter switch and watch the servo respond. You should see smooth transitions between your preset camera angles. Fine-tune the minimum and maximum values until you achieve your desired tilt range without the servo buzzing at its limits. Most FPV pilots set up three positions: looking down for racing, level for cruising, and tilted up for high-speed flying.
