INAV 7 is the last INAV official release available for F411 based flight controllers. The next milestone, INAV 8 will not be available for F411 boards.

The GPS NMEA protocol is no longer supported. All pilots are required to switch to UBLOX protocol. All modern GPS modules (even as old as from 2015 and earlier) support UBLOX protocol and there is not a single good reason to stick to NMEA nowadays

The FrSky D-series telemetry support has been removed. This applies to legacy D4R receivers and some 3rd party whoop boards

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.

Please follow the instructions on this page.

INAV now was a function that allows to flexibly assign functions to PWM outputs directly from INAV Configurator. Specific function AUTO, MOTORS or SERVOS can be assigned to each Timer Group. Then, all outputs from this group will perform this function. Thanks to this, it's possible to use servos and motors in ways that previously required building a custom targets.

Bear in mind:

This has been a frequent request since PNP VTOL models started becoming more common.

The Ez Tune is a simplified tuning framework similar to Betalight's Simplified Slider Tuning. Instead of setting each PID controller gain, rate, and filter setting separately, Pilot is presented with 8 sliders for:

Ez Tune settings are not compatible with Betaflight Slider Tuning setting and cannot be migrated directly.

Read the description in Configurator's Ez Tune tab on what each setting does and how it should be used.

With INAV 7.0 came the ability to Emergency Rearm. This allows you to rearm in flight when you accidentally disarm. You need to do this within 5 seconds of disarming. Which sounds short, but is actually a pretty long time. Emergency Rearm can be used after a launch and while the aircraft still believes it's flying. It bypasses safety checks (including the throttle position) and doesn't trigger auto launch. Multirotors will also briefly switch to Angle to stabilise and level the flight. You can read all about it at https://github.com/iNavFlight/inav/pull/9254

INAV 7 adds the DMA Burst mode to selected target as ultimately fixes the problem of DSHOT protocol not working on some boards. Pilots do not have to take any actions, DSHOT is just available on previously affected flight controllers. This applies to:

The JETI EXBUS protocol should now not hang the flight controller during operation. The issue was originally fixed in betaflight/betaflight#13130 . Thank you @SteveCEvans and @klutvott123

The Cruise Mode for Multirotors allows pilots to let go the radio sticks while UAV flies on a predefined course with predefined speed. Just like with regular PosHold, Throttle stick sets the altitude and course, while the pitch stick is used to set the horizontal speed. When released INAV will hold set speed, altitude, and course.

As mentioned in the Important Notes section, INAV 7 no longer supports the GPS NMEA protocol. All modern GPS module support one of the UBLOX protocols and as a result pilots must switch to either UBLOX or UBLOX7 protocol.

A number of improvements have been made to GPS support in INAV 7.

It is now possible to select multiple GPS constellations, and not only Galileo. If your GPS modules does not support a particular combination, it will fallback to no extra constellations.

M10 GPS units will now default to 10Hz, like M8 units and a new cli setting has been added to allow overriding the update rate of your UBLOX7 GPS (gps_ublox_nav_hz). This should allow you to fall back to 5Hz or bump it up to the limits of what is supported by your GPS module.

INAV now support MSP VTX when using MSP DisplayPort OSD.

Now it is possible to change VTX power levels and channels via INAV's OSD menu or ELRS backpack without connecting the SmartAudio wire on HD-Zero VTXs.

If you MSP DisplayPort OSD is working, no extra configuration is needed.

AT_LEAST_LINEAR_DESCENT is no longer a method for RTH. It has been replaced with a more flexible linear descent option that will work with any RTH method. If previously using AT_LEAST_LINEAR_DESCENT, you should now just use AT_LEAST as the RTH type. Linear Descent is now a separate option that can be used with any other RTH method. To make this possible, the target altitude of the descent is now the nav_rth_home_altitude. In some cases, if flying below the home position, this will work as a linear ascent.

You can also decide when the linear descent will start. Set the nav_rth_linear_descent_start_distance parameter to the distance (metres) from the home point, where you want to start descending. Set to 0, the default setting; the descent will start immediately, as with the pre-7.0 implementation.

These options are available in Configurator.

See the Navigation Mode: Return to Home wiki for more details.

You can now have custom pilot logos on your OSD and arming screen (HD Only). You will need to create a custom font with your logos to show them on screen. The OSD logo is a 3x1 character symbol. This can be used with both analogue and HD. The arming screen logo is a 10x4 character image, and only works with HD systems.

More details are available in the OSD Document.
