I’ve noticed of late some crashes amongst new Mavic Mini users, many of the crashes and fly away’s seem to occur at take off or shortly after take off, so I have posted below a very short preflight exercise before taking to the sky, I have been using this preparation before flying since I began flying, it’s a pretty simple process takes very little time , but will give you some confidence of knowing as your craft flys that you have reasonably checked that GPS, COMPASS & IMU are working well.
There are other preflight checks you should make and I will post my checklist later, but for now try checks below and you will find that they are efficient and quick and will not delay your departure to long .
1/ start AC leave until you receive enough gps lock , 11 is a good number .
2/ if you get Compass interference turn off AC and move to another location, without interference, if you still get warning preform calibration at safe location .
Raise AC to height of 8ft Hover for 20 seconds Fly forward 2ft Backward 2ft Left 2ft Right 2ft Up 2ft Down 2ft Yaw left Yaw right Each time returning to hover position If you have a good horizontal each time, you will then know you have good GPS good IMU and good Compass, and your ready to fly.
This exercise takes less than 2 minutes and is worthwhile doing before every flight,
One thing to remember is left stick pull down 100% if anything is not right, this is the quickest way to land your craft safely, and left down is easy to remember .
