Note! Magnetometer should not be enabled for planes because it can conflict with the GPS readings for direction. However multirotors must have the mag enabled to use Nav flight modes.

iNav Cleanflight is fork from regular Cleanflight on Github. It is Cleanflight with GPS navigation added to it.

If you purchased the version 2.1 of the Omnibus F4 Pro flight controller you may be surprised by the receiver or GPS not working properly when they are both connected at once. The problem arises from a conflict with the receiver port and the port where the GPS is connected. This is not a problem on the other Onibus versions 1,2 or 3. The solution is to move the GPS to a different port than is normally used. This issue and the issue with the receiver port now being on serial/UART poet 6 can send you on a wild goose chase when configuring this board. Chances are if you have a GPS connected you will be using iNav Cleanflight. The iNav CleanFlight Wiki can be a good resource but not always easy to find find what you are look for. I found the solution on the WIki in Issue 2576 and I have posted a link to it below:
https://github.com/iNavFlight/inav/issues/2576
If you read through the discussion you will see it was a little hard to figure out what the problem was but eventually it became apparent that there was a serial port conflict and the GPS had to be moved to a different port.
Also included in the issue discussion we find that the FrSky X8R SBUS receiver would not connect without a different version of the firmware than expected.
I decided to use a D4R-II Receiver in PPM mode instead of the X8R and it connected very easily with standard firmware OmnibusF4V2.
Luckily you don't have to read all Wiki discussion. Instead just watch this video instead and I think you will understand.
