I still have problem with compass: airdate, black box. Almost every day. Sometimes mistakes happen far in the field. Sometimes not far from me. Spark rotates a little counter-clockwise or GPS Weak signal. Turns if it's a long time to fly straight.
I calibrated in the field repeatedly.
p.s. 2. no error message before take off . - same.
Hi Mishanki, looking at your video/log, a couple of things in the video you are flying quite low also in sports mode, flying over the surface which is grass and light is not great , this will impact on VPS ability to hold or lock on to surface so may cause that drift right at the end of your flight.
Regarding compass problems these are most certainly caused by some magnetic interference as we see what is fairly common now starts with magnetic yaw then compass problems then followed by IMU heading off, IMU heading off is caused by compass pulling off in a different direction than controller is commanding so IMU cannot hold Aircraft at correct attitude so you get a warning about exception heading.
What I would do first is an IMU calibration you have to do this on a very level surface check this with a sprit level before doing IMU. I would also do a RC calibration.
Then I would go to a completely different location as Watchberger said, calibrate compass make sure no metal objects near by watches phones rings cars, no concrete etc No remote control within 5 metres and calibrate compass.
I will leave link for you to try testing before you fly on a mission and also when testing test above 32ft. |
