Ok so had my MP for about 60 faultless flights.
On FW .400 and never updated because it worked flawlessly.
Today I flew it about 300m away from where I live at a mates new place.
Got home point set. Took off and hovered. Checked home point again. Took it up to about 30m to get some video. Then all a of a sudden just took off in atti mode with the RC disconnected. It had 17 Sats but NO GPS.
It flew in a straight line to a position over 500m away. I had no control. I had no RTH or pause button, it just kept going. Eventually it picked up a GPS and because no connection it did RTH to the correct location where I landed it.
On the flight log it looks like it lost GPS and thought it was in a different location and tried to correct itself by flying back to that false position. The red triangle for the AC jumps from where I was to this random position 500m away instantly.
Luckily it was at a height that was high enough not to hit anything.
Any ideas?
Bad compass/imu?
Why would you lose GPS with 17/18 sats and the controller all at the same time?
Really worried to fly again now.
Will do compass and IMU cal first though.
