If is the same motor all the time check your throttle range.
Do throttle calibration again.

You will find sometimes on start up some motors will spin faster than others? its pretty random and why.. I dont know, it`s all in the firmware, just raise your idle speed and it should cure the one motor not firing up

My yellow flash for normal flight turns to a light yellow rapid flash at first level of battery warning. It's not quite green, but it's definitely not the dark yellow and definitely not the white.
FWIW, I remember it used to rapid flash the darker yellow and seems like I've lost an LED at some point in time.

Else, if it is green that would signal an IMU data lost error. What does that exactly mean and how would I correct the problem?
Thanks.

It's definitely an IMU Issue and not "inadequate gps reception".
I can see triple white flash in both GPS and atti mode too.

If you took that footage with a gopro, it should have been much smoother IMO being hard mounted to an s800, so check prop balance on all props and make sure they are perfect. Hub balance them too with CA if required.

If that does not work, then reset your WKM to default, check your mounting, recalibrate your mag, and try again.

Also gives me white flashes in manual though..

- In GPS-atti it's stays pretty tight in it's 2m diameter, but it does drift of a bit when yawing, flies back to original location after yaw though. Also, frequent triple white led flashed, possibly inadequate gps reception?

- In atti-mode there is a SERIOUS drift to the left! I have to keep on giving it counter-aileron to the right to keep it from flying of.. This is what's bugging me the most. It must be a IMU problem since it stays perfectly stable in Manual-mode...
Also occasional triple white flashes, maybe a compass misreading? I did do a succesfull and clean calibration just before this flight though... The IMU is not touching the sides op the top-plate...



What could be wrong?
How can I get rid of the sideways drift in atti- mode? This is my main concern, since it flies pretty good and I don't notice a difference in flying-characteristics with the white flashes or without.

here are my settings (it's a basic S800 with the gps mounted on the longest pole fairly in the center, and with one Gens Ace 10ah 6S attached underneath the centerplate.)

It's normal, all motors will keep same spin speed unless an absolute horizontal is guaranteed.

Colin, CEO of DJI NA, does a great job at explaining the WKM. The videos are much more professional than those that users have done. I hope that DJI posts links on their website. It will be of great use to new users. Thanks, Colin.

I agree, just videos and as I'm about to purchase the WKM it is very good timing.

One thing I didn't completely understand from the flight modes video was the stabilization.

If you let go of the sticks in manual mode, does the WKM keep the copter level?

Thanks

crcr,

Not in Manual mode, in ATTI and GPS/ATTI only.

Thanks, So in ATTI mode its auto leveling but means the Altitude hold is always on?

So there is no way to have the altitude hold switched off but still have auto level?

If you wanted to take some photos at various heights and raise altitude slowly on the same spot you would need to be in GPS/ATTI mode. Is it easy to raise the altitude slowly without the WKM trying to fight to keep the same original altitude?

Thanks
Craig

if you move the throttle stick above 50% (in Atti and GPS-Atti) the copter climbs (climb speed dependent on your stick position)
if you move the throttle stick below 50% (in Atti and GPS-Atti) the copter descents (descent speed dependent on your stick position)

(this you can also read in the manual)

best regards

Ferdinand

Sorry I do not understand? do you mean to say that after the CSC input the motors should all run at the same speed? without throttle input... If that is the case, mine do not, at least on the S800 they don`t. There are two motors that always spin much slower than the other 4 until takeoff when the imu notices an imbalance and corrects it.

I had that issue with my NAZA. It ended up being my ESC's were not all calibrated to the same end points. Try recalibrate and see if that helps.
