Could anyone help me? I've build a long range 7" quad with Matek F-405SE FC. I've successfully instal INAV 5.0 firmware. It works like a charm, but the only confusing point(besides unexpected RTH behaviour) is that when I'm starting to calibrate compass (using mode 2 RC combination: left stick upper right + right stick down) where is no any "beep" at the calibration begining - only FC led blinking. The calibration process finishes successfully within 30 sec with "beep" and compass works fine, but it's a bit confusing... Last weekend it was shiny day and it wad hard to recognoze FC leds blinking, so the calibration process was a bit triggy...
