Second flight of the day ends in disastrous crash. At the beginning of the flight I lost the GPS signal, the recovery was in 3D mode which is a standard flybarless control unit. Things got hairy but I recovered and landed. I reset the heli and the GPS linked. I spooled up in GPS setting and took off but immediately the GPS link was lost again things rapidly got worse and the ending was a crash. Lesson of the day if things are right dont fly.
