running hexa with 3.4.4 and for the first time since running 3.4 while on a simple loiter I had a sudden EKF variance and a switch to failsafe (althold in my parameters)…why did this happen with dual GPS and no change on GPS HDOP at all in either GPS? concerned as this led to a flyaway that I caught on time to RTL since EKF error cleared…any ideas? is this a bug?2.zip (4.2 MB)
