Important Notes

F3 Removal

STM32 F3 flight controllers like Omnibus F3 or SP Racing F3 are no longer supported in INAV. If you are still using F3 boards, please migrate to F4 or F7.

The supporting code will be retained for a few more releases, but will not be maintained and is not guarantee to build or work properly in future.

Upgrading from 2.6, 2.6.1

  1. Download and install the new configurator
  2. Save to a file the current diff all from the CLI.
  3. Upgrade to INAV 3.0 using the Full Erase option in the configurator.
  4. Upload your OSD font of choice from the OSD tab.
  5. Go the CLI again and paste the contents on the file you previously create and write save , press ENTER and done!
  6. You should be ready, explore new 3.0 features and enjoy!

Upgrading from 2.5 or older version

Please follow the instructions on this page.

New targets:

  • Diatone MambaF405US_I2C
  • Mamba F722_I2C
  • FLYWOOF411_V2

CLI:

New commands

None (TBC).

Changed Settings

Setting Description
receiver_type Default: target
blackbox_device Default: target
platform_type Default: MULTIROTOR
log_level Default: ERROR
rssi_source Default: AUTO
nav_overrides_motor_stop When set to OFF the navigation system will not take over the control of the motor if the throttle is low (motor will stop). When set to OFF_ALWAYS the navigation system will not take over the control of the motor if the throttle was low even when failsafe is triggered. When set to AUTO_ONLY the navigation system will only take over the control of the throttle in autonomous navigation modes (NAV WP and NAV RTH). When set to ALL_NAV (default) the navigation system will take over the control of the motor completely and never allow the motor to stop even when the throttle is low. This setting only has an effect on NAV modes which take control of the throttle when combined with MOTOR_STOP and is likely to cause a stall if fw_min_throttle_down_pitch isn't set correctly or the pitch estimation is wrong for fixed wing models when not set to ALL_NAV
nav_rth_climb_first New: ON_FW_SPIRAL

New Settings

Setting Description
gyro_anti_aliasing_lpf_hz Gyro processing anti-aliasing filter cutoff frequency. In normal operation this filter setting should never be changed. In Hz Values: 0 - 255 Default: 250

imu2_use_for_osd_heading If set to ON, Secondary IMU data will be used for Analog OSD heading Default: FALSE
imu2_use_for_osd_ahi If set to ON, Secondary IMU data will be used for Analog OSD Artificial Horizon Default: FALSE
imu2_use_for_stabilized If set to ON, Secondary IMU data will be used for Angle, Horizon and all other modes that control attitude (PosHold, WP, RTH) Default: FALSE

turtle_mode_power_factor Turtle mode power factor Values: 0 - 100 Default: 55
servo_autotrim_rotation_limit Servo midpoints are only updated when total aircraft rotation is less than this threshold [deg/s]. Only applies when using feature FW_AUTOTRIM. Values: 1 - 60 Default: 15
prearm_timeout Duration (ms) for which Prearm being activated is valid. after this, Prearm needs to be reset. 0 means Prearm does not timeout. Values: 0 - 10000 Default: 10000
airmode_type Defines the Airmode state handling type. Default STICK_CENTER is the classical approach in which Airmode is always active if enabled, but when the throttle is low and ROLL/PITCH/YAW sticks are centered, Iterms is not allowed to grow (ANTI_WINDUP). THROTTLE_THRESHOLD is the Airmode behavior known from Betaflight. In this mode, Airmode is active as soon THROTTLE position is above airmode_throttle_threshold and stays active until disarm. ANTI_WINDUP is never triggered. For small Multirotors (up to 7-inch propellers) it is suggested to switch to THROTTLE_THRESHOLD since it keeps full stabilization no matter what pilot does with the sticks. Fixed Wings always use STICK_CENTER_ONCE or STICK_CENTER modes. Default: STICK_CENTER
airmode_throttle_threshold Defines airmode THROTTLE activation threshold when airmode_type THROTTLE_THRESHOLD is used Values: 1000 - 2000 Default: 1300
fw_d_pitch Fixed wing rate stabilisation D-gain for PITCH Default: 0
fw_d_roll Fixed wing rate stabilisation D-gain for ROLL Default: 0
fw_d_yaw Fixed wing rate stabilisation D-gain for YAW Default: 0
fw_yaw_iterm_freeze_bank_angle Yaw Iterm is frozen when bank angle is above this threshold [degrees]. This solves the problem of the rudder counteracting turns by partially disabling yaw stabilization when making banked turns. Setting to 0 (the default) disables this feature. Only applies when autopilot is not active and TURN ASSIST is disabled. Values: 0 - 90 Default: 0
fw_level_pitch_trim Pitch trim for self-leveling flight modes. In degrees. +5 means airplane nose should be raised 5 deg from level Values: -10 - 10 Default: 0
smith_predictor_strength The strength factor of a Smith Predictor of PID measurement. In percents Values: 0 - 1 Default: 0.5
smith_predictor_delay Expected delay of the gyro signal. In milliseconds Values: 0 - 8 Default: 0
smith_predictor_lpf_hz Cutoff frequency for the Smith Predictor Low Pass Filter Values: 1 - 500 Default: 50
nav_land_minalt_vspd Vertical descent velocity under nav_land_slowdown_minalt during the RTH landing phase. [cm/s] Values: 50 - 500 Default: 50
nav_land_maxalt_vspd Vertical descent velocity above nav_land_slowdown_maxalt during the RTH landing phase. [cm/s] Values: 100 - 2000 Default: 200
nav_rth_alt_control_override If set to ON RTH altitude and CLIMB FIRST settings can be overridden during the RTH climb phase using full pitch or roll stick held for > 1 second. RTH altitude is reset to the current altitude using pitch down stick. RTH CLIMB FIRST is overridden using right roll stick so craft turns and heads directly to home (CLIMB FIRST override only works for fixed wing) Default: FALSE
nav_max_altitude Max allowed altitude (above Home Point) that applies to all NAV modes (including Altitude Hold). 0 means limit is disabled Values: 0 - 65000 Default: 0
safehome_max_distance In order for a safehome to be used, it must be less than this distance (in cm) from the arming point. Values: 0 - 65000 Default: 20000
safehome_usage_mode Used to control when safehomes will be used. Possible values are OFF, RTH and RTH_FS. See Safehome documentation for more information. Default: RTH
nav_mc_wp_slowdown When ON, NAV engine will slow down when switching to the next waypoint. This prioritizes turning over forward movement. When OFF, NAV engine will continue to the next waypoint and turn as it goes. Default: TRUE
mavlink_version Version of MAVLink to use Values: 1 - 2 Default: 2
osd_telemetry To enable OSD telemetry for antenna tracker. Possible values are OFF, ON and TEST Default: OFF
osd_stats_min_voltage_unit Display minimum voltage of the BATTERY or the average per CELL in the OSD stats. Default: BATTERY. Options BATTERY, CELL
osd_ahi_reverse_roll Default: FALSE
osd_ahi_max_pitch Max pitch, in degrees, for OSD artificial horizon Values: 10 - 90 Default: 20
osd_plus_code_short Number of leading digits removed from plus code. Removing 2, 4 and 6 digits requires a reference location within, respectively, ~800km, ~40 km and ~2km to recover the original coordinates. Default: 0
osd_sidebar_height Height of sidebars in rows. 0 leaves only the level indicator arrows (Not for pixel OSD) Values: 0 - 5 Default: 3
osd_pan_servo_index Index of the pan servo to adjust osd home heading direction based on camera pan. Note that this feature does not work with continiously rotating servos. Values: 0 - 10 Default: 0
osd_pan_servo_pwm2centideg Centidegrees of pan servo rotation us PWM signal. A servo with 180 degrees of rotation from 1000 to 2000 us PWM typically needs 18 for this setting. Change sign to inverse direction. Values: -36 - 36 Default: 0
vtx_smartaudio_early_akk_workaround Enable workaround for early AKK SAudio-enabled VTX bug. Default: TRUE
dji_speed_source Sets the speed type displayed by the DJI OSD: GROUND, 3D, AIR Default: GROUND

New features

Turtle mode (@kernel-machine)

WP mission sealevel altitude datum (@breadoven)

Prior to inav 3.0, mission waypoint altitudes are relative the arming location. It is now possible to define waypoints with absolute (AMSL) altitude, making the mission independent of the arming location. See the inav wiki for details (WP paramater3)

WP Mission Landing Elevation Setting (@breadoven)

The relative / absolute ground altitude of a LAND waypoint may be set as WP paramater3 (m). See the inav wiki for details.
