Like you can rotate,flip and have settings for the gyro on a FC in BF/iNav, etc., does the same apply to iNav/Compass/GPS on a wing?
We can have a good look tomorrow (@Steviegeek , etc but I remember loiter/RTH didn’t work on this wing before (the ZoHD)), so be nice to get it working, etc… iNav 4.1 (and no, no time to update this before flying tomorrow!)
The gps has to be the right way up. That’s it.
what he says 
also if running INAV or BF no compass needed,
If running ARDUPLANE then a compass is now recommended (there’s been issues with speed calculations causing a few crashes without)
nto had issues with gps location, just RTH and loiter, being a PITA! Anyways, can look, cheers guys!
We’ll look at your settings tomorrow and test on Rich’s jet
