    High altitude F550 hexacopter crash after motors stop. Anyone know why?

    I believe the sound you hear from propellers when descending are not the motors that start, it's autorotation that kicks in when the speed get high enough. I have experienced this myself when shutting off motors by mistake. The sound is different when propellers going backwards, and they will...

    Ho9w do I Downgrade to 5.16?

    The safety feature for motor failure on hexa came With Version 5.14. So no problem running 5.16 if you prefer that over 5.20. Release notes for all Versions: http://download.dji-innovations.com/downloads/wkm/en/Wookong_M_product_release_notes_en.pdf

    Frsky

    If there is noe light, either it's not getting correct power or the rx is dead. Are you sure you have not reversed the powerleads? Not sure what type of rx you have, but the D8R is good for 3.5 to 10V, so 7.4V should not have burned it.

    WKM v.5.20 experiences

    I actually experienced somthing like this. I have changed ESC's and wanted to stress test them with max load to be sure they don't get too hot. So I added 1kg+ more than I usually carry, total around 6kg. After a while I had to increase throttle to 75% just to keep altitude. I thought it was due...

    WKM v.5.20 experiences

    Thanks. I have flown around 15 battery packs now, everything feels ok. If I should make a comment, it would be that the altitude hold seems to be more dependant on the throttle stick being placed at the exactly right place. But I upgraded from 5.02, so this may have been changed a long time...

    WKM v.5.20 experiences

    I've been using v.5.02 for a year or so now. Never had any problems with it. But I wanted the new redundancy feature that DJi included in the firmware from v.5.16, in case a prop or motor breaks on my hex, so I upgraded to 5.20 now. I've started testing, everything works great with the same...

    DJI site virus?

    I suspect a false positive from your antivirus. The webpage did not trigger any of these 31 antivirus services: https://www.virustotal.com/url/fd22c91f38ff388a6f5274bcd6f8b4adfe4810fd8c05d4c3ac616e8726e42eeb/analysis/1353174362/

    DJI WKM GPS failure

    I'm still on v.5.02 because I hear people having problems with newer versions. Is this GPS problem the cause of all the problems people has experienced with wkm? So if I got the old gps it would be safe to upgrade to the last version? Never had any problems with my wkm running 5.02. Have used...

    breaking the Go-H

    The voltage protection feature is a total useless function for anything else but experimenting. You do not want the machine to override your controls and make decisions for you! Get yourself a Lipo alarm or telemetry showing battery voltage, so you know when to land.

    Leaving Well Enough Alone

    I really can't say if the reason my wkm equipped machines is still alive is caused by sticking to old firmware, or because I'm very careful with testing, props, motors, soldering etc. I do know that I have all I need for the moment with v.5.02 except the redundancy feature. I'm doing AP missions...

    Leaving Well Enough Alone

    Just remember that the advanced functions, like return to home and poi heading, does not exist in 5.02. You can set up fail safe to return home, but it's not a function that can be activated by a separate switch. The only "advanced" function I have used is the home lock. So I'm able to pull the...

    Leaving Well Enough Alone

    As i'm doing AP work, I can not risk upgrading without spending days and weeks testing the upgrade in open fields. Loosing or crashing my multirotor at work will be very expensive and has the potential to hurt someone. So until the majority reports a new flawless version, I won't upgrade...
