I've been flying my fpv quad for the past few months and want to add a servo to the build. I saw another thread saying you could use a tx pad to send a signal to a servo so I've been trying to do that. I've remapped it in the CLI to be a servo, I've checked "SERVO_TILT " in the config tab, and have also set up a signal on my aux 4 which betaflight shows is working. It's still not working so I'm sure I'm missing a step. Thanks for any help you can provide!
