Hi guys
P3S, 1.7.90 FW and 3.1.0 IOS DGI Go
This is a 3 week old Phantom 3S. On the first flights, apart from Strong Interference errors, all was good.
Last weekend it got a lot of compass errors, dropping into atti. I send the flight logs to DJI and they responded with a RMA authorisation for repair.
Before sending back I decided to test again today. Similar conditions, around 5C dropping to 3C, no wind, good sats. I did a IMU calibration last night, and compass cal before flying. Compass mod looked good - around 1550.
flying site is the shore well away from anything, no metal, no radio towers, no wifi.
However, same errors this time, plus a new one to me - yaw error.
I was able to fairly reliably reproduce the error by slowly rotating CW, then when it was pointing approximately West it would give a compass error warning, drop to atti. Continuing the rotation past west would clear the error (mostly).
I did also get a few errors when it was pointing east - so the west may just be a coincidence, but I replicated it many times. Strangely, rotating CCW didn't cause the error.
Here is the phantomlog from the 1st flight Phantom Log Viewer - PhantomHelp.com
and the healthydrones from the same flight HealthyDrones.com - Innovative flight data analysis that matters
There are more flight logs from subsequent flights, but I haven't checked them yet.
So, DJI have offered a RMA. However, that means sending to Netherlands and being without a quad until some time in January, with no guarantee of a fix. I'm thinking the better option would be to return to the retailer (argos) for a refund and get a new new one - perhaps stump up the extra and get a P3A.
Any thoughts?
