Note

Make sure to remove props and check your motor and servo outputs before powering your upgraded flight controller with a battery for the first time. The changes to enable flexible motor and servo allocation may change what outputs your configuration uses by default.

Known Issues in 9.0

  • Please read INAV Github issue reports for outstanding problems that were not resolved in time for the release.

Upgrading from a previous release

Upgrading from INAV 8.0

  1. Backup configuration with CLI diff all command or use the Diff All and Save to file buttons.
  2. Download and install the new INAV Configurator 9.0
  3. Flash INAV 9.0 WITH Full Chip Erase option enabled
  4. Load your 8.0 Diff settings in to the CLI. Then take a note or write down the incompatible settings changes marked in RED.
  5. Then copy your 8.0 Diff file and rename it 9.0. And edit the old incompatible settings.
  6. Now go to the Status Tab and press the Reset Setting button.
  7. Select Keep current settings from the defaults pop-up.
  8. Go to CLI and load your edited INAV 9.0 Diff
  9. Done

Tip

Concerning step 8.
It can be a safer option to load your Diff All settings in two parts if you are using multiple Profiles. e.g. Control, Mixer or Battery.
This can be done by copying and loading the Diff All text setting from the top, down to the bottom of the # master settings category. Then load that into the CLI and press enter. Once it has written, press the Save Settings button.
Wait until it reboots and go back to the CLI tab again, then copy and load the rest of the Diff All text file. Starting from the # Control_profile 1 settings category, down to the bottom. Press enter. Once written, it will save by itself.

Upgrading from older versions

Please follow the instructions on this page.

Highlights

Minimum ground speed flexibility

Via the Programming Framework. It allows the user to have more flexibility when flying in higher wind conditions. To ensure the airplane makes headway.
In addition, you can program it to dynamically adjust the minimum ground speed according to the Wind direction and Wind speed.
More information can be found in this link.

OSD throttle gauge

Allows the pilot to see the throttle as a vertical digital gauge.
Functional information can be found here in the PR link

Fixed wing altitude controller

Changes have been made to improve its operation on a broader range of airframes. One of two methods can be selected to better suited different climb rate conditions.

  • Altitude Velocity controller nav_fw_alt_use_position = OFF (default)
  • Altitude Position controller nav_fw_alt_use_position = ON

See here for more information. And the required PID tune settings for either control method.

Position estimator improvements

Changes to the position estimator are mainly intended to improve issues with Z velocity accuracy but also includes code clean-ups and fixes.
There has also been setting changes added with the code alterations. Depending on the sensor data quality. It may be beneficial in some cases to revert your settings back to the old ones, or somewhere in between the two.

Name CLI Old New
w_z_baro_v 0.1 0.35
inav_w_z_gps_p 0.2 0.35
inav_w_z_gps_v 0.1 0.35

More information directly related to the changes can be found here.

Other changes:

  • Barometer altitude added to CRSF telemetry.
  • Better Fixed wing flight detection to handle auto disarm on landing. PR link
  • Lulu filter fixes and improvements. PR Link
  • Accelerometer and Barometer temperature compensation for better altitude control - Calibration method and PR link.
  • Add flights counter to stats PR link
  • Servo speed filter for tilt-rotor VTOL. PR link
  • Enhance VTOL tilt-rotor support. To assist transition smoothness PR link
  • Better air cushion compensation for multicopters and rangefinder fix. PR link
  • Improved yaw estimation for magless multicopter operation. PR link - The default ahrs_acc_ignore_rate setting has also been lowered from 20 to 15.
  • Mavlink clean-ups and fixes - 11060 11061 11062

OSD/CMS changes

Name Function
OSD_VERTICAL_SPEED_INDICATOR New name for OSD vario
OSD_ADSB_WARNING CMS stick menu
OSD_ADSB_INFO CMS stick menu
OSD_THROTTLE_GAUGE OSD
OSD_NAV_MIN_GROUND_SPEED OSD

Functions

Function Name Values
Battery SMARTPORT vbat_meter_type , current_meter_type
Programming Framework Gimbal Sensitivity Scales Operand A from [-16 : 15]
Programming Framework Override Minimum Ground Speed When active, sets the minimum ground speed to the value specified in Operand A [m/s]. Minimum allowed value is set in nav_min_ground_speed. Maximum value is 150
Programming Framework Minimum Ground Speed [m/s] The current minimum ground speed allowed in navigation flight modes
Programming Framework Horizontal Wind Speed [cm/s] Estimated wind speed. If the wind estimator is unavailable or the wind estimation is invalid, -1 is returned
Programming Framework Wind Direction [deg] Estimated wind direction. If the wind estimator is unavailable or the wind estimation is invalid, -1 is returned
Programming Framework Relative Wind Offset [deg] The relative offset between the heading of the aircraft and the heading of the wind. 0 indicates flying directly into a headwing. Negative numbers are a left offset. For example, if -20° is shown, turning right will correct towards 0. If the wind estimator is unavailable or the wind estimation is invalid, 0 is returned
