[crash1sttime]

just about to fly in Portugal and my quad is flashing 4 red green then 2 long red

I’ve checked IMU all ok and calibratedthe compass but still the same

Any ideas lads

Seems it may be a no fly zone of some sort, yet UAV data says I’m well outside, I’ve moved away about a mile and it’s all greens now
