I've recently installed a MinimOSD which I've set up and flashed twice, it detects the heartbeats and looks ok for a few seconds then just puts up and overspeed warning.
I seem to be able to cycle through three warnings including overspeed and battery by using left and right aileron, am I doing something wrong.. Why does the main screen dissapear?
I have this exact same issue. I had it working but then i changed some stuff around and now its broken.
For me, its works fine until i turn on my transmitter.
Its hard to fly without a transmitter.
Did you every find a resolution?
OK I figured it out really quickly. Its to do with mode switching. not sure why but for me i had something set to CH8 and i must have Ch8 set to mode switch in minim. So change that or your transmitter and you should be set.
hope this helps.
