INAV settings and using Launch Mode

1， Launch Mode Configuration

1.1 Setting up Automatic Launch Mode

Go to the Modes page, according to your habits, assign a channel to the NAV LAUNCH mode, and save.

1.2 Configure in CLI

set nav_fw_launch_accel =1600      Detect the acceleration value for takeoff

set nav_fw_launch_detect_time=40      Detect the takeoff delay, and apply throttle 40ms after the throw.

set nav_fw_launch_thr=1850      Takeoff Throttle

set nav_fw_launch_motor_delay=160      Takeoff Motor Delay

set nav_fw_launch_timeout=7000      Automatically cancel launch mode if not taken off after 70 seconds

set nav_fw_launch_climb_angle=25      Takeoff Angle

1.3 Or configure in the ADVANCED TUNING section in INAV

2， Launch Mode Operational Sequence

1. After the aircraft passes the self-check, unlock and check if the motor is functioning properly, then lock it again if everything is normal.

2. Select the flight mode you want to use after the launch is complete and switch the lever to this mode.

3. Flip the launch mode switch, unlock, and push the throttle lever to 70% (the percentage of throttle can be judged based on the performance of the aircraft, at least ensure it's at the minimum cruise throttle + 10%).

4. Observe whether the motor is spinning and whether there is a 'beep' sound from the USB board buzzer when applying throttle (check if the buzzer switch on the USB board is turned on), and if the control surfaces are raised. If the motor does not spin and the control surfaces are raised, it has entered launch mode.

5. Shake the aircraft back and forth by hand to give it an acceleration. Wait for the motor to start spinning before throwing the aircraft (if the settings are appropriate, you can also throw it without waiting for the motor to start spinning, but this is not recommended for beginners

6. After the aircraft has taken off and reached the safe height you desire or the maximum height set for the launch, you can turn off launch mode and take control of the aircraft.
