k, been lurking here for about 2 months & haven't found a need to post - until now.
my setup is yellow fly more package Spark w/3 batteries, everything bought directly f/DJI. iPad Mini 3 wifi running 9.3.3 is device tethered to R/C. all AC, RC & battery firmware is current as of 9/2 mandatory update.
so, flying on 9/4 in some farmland next to the hills, i randomly got several uncharacteristic errors - flight record here
please note that i've had no errors of any type whatsoever before this in 50 previous flights, no crashes either.
(also, i understand the rookie mistake w/RTH after compass errors - lesson learned & moving on...)
since then, i've been doing systematic troubleshooting to determine where the problem might lie:
1. two more test flights on same day @ local field revealed back to back IMU errors (same as original)
2. recalibrated IMU
3. flew once & got another IMU error on 9/7 (flight record here), then recalibrated compass directly afterwards - behaved fine for two subsequent flights
4. rolled back Go app to 4.1.7 (just as an experiment since everything worked flawlessly before i upgraded to 4.1.9)
5. recalibrated IMU & compass again after app rollback (for the sake of consistency) - flew fine for a third flight on 9/8 (compass was recalibrated in middle of open farm field)
6. test flew today @ local field, got both IMU & compass errors again - flight record here
7. recalibrated compass again (i know - shouldn't need to, but bear w/me as again it's for consistency)
8. afterwards observed slight TBE, drifting, etc., but no errors in two subsequent cautious low altitude test flights which clearly suggests issue(s) persists
(please note that i calibrated compass @ local field a month before any of this even occurred w/no errors)
if memory serves, KPH level has been low (4 or less) during every aforementioned flight
any initial impressions, observations, theories, etc?
more importantly, what's the best way to escalate past the typical DJI support runaround & get this thing returned for service as quickly as possible?
BTW, thx for your patience in reading my Dragnet diatribe
John
