My x 650 v8 has problems on both software versions with white lights flashing a lot. also main issue on RTH on decent. craft will start going in clock wise circles getting larger as it desends. and altitude hold in middle stick is not oporating correctly. stability is ok in atti mode but in gps/atti mode less stable.I have not played with the gains much as trying to get the bugs out of the RTH and gps atti mods. currently set at 125% roll/tilt also have had craft not come home in RTH / fail safe mode. several times has stayed in a hover not returning. moved 10 feet in sky activated fail safe again and returned. also in gps /atti will yaw upto 360% if sits for a little while. also in RTH decent will rotate. here is a vidio clip on bottom. in this vidio Im running assistant 1.11 and firm ware 4.2 in this vidio it performed its best in gps atti mode. older version soft ware and firm seems to have better gps ability.

I noticed old software RTH when activated craft will come in backwards or does not care about orintation. new software comes in nose first.

Sorry Gary!!!
Well today I got my testing in. Im starting to go crazy. did I swap wires or not. ooo boy. Well in the end its a quad and re tested and checked.
conclusion. octo was a little more stable and the quad still had all the same bad habitts. White light double flashing. as well as not holding position it walked over 30 feet at one point at a snails pace. and if flying in gps/atti mod and slow down and release the sticks. she tends to go into a clock wise circle pattern. this is not on rth. this is just flying quad slowly around yard testing reactions to inputs and holding capability. as well as drifting from hold position with buble white lights flashing, once white lights stop. When they do!! it will abruptly currect. I will chech with Dji inovations on the speed controllers AKE 8s3512sct 12 amp high speed pwm. these are sold by cnc heli for running with the DJI system up to 500 mhz refresh rate. this is the last step in trouble shooting for me. down to speed controllers.

Gary thought speed controllers where not up to the task as when I increased the gain it never hit a wobble. got all the way up to 290 on pitch. not good once it had wind hit or got ossolating it created chain reaction and got viollent.

this is what I perchased. But the esc say AKE 8s3512sct
I can not find this part #. does any one know what it is?

I see 2 issues from what you have listed..
1st the Props are too small .. The XAircraft website says 12-6 props and (2) you should have at a minimum 18amp controllers .. Make sure to program the controllers (ESC'S) so they are all matched and make sure the rotation is according to DJI's software and not XAircraft .. Also the Measurements of components are critical and must be accurate for the aircraft to fly properly. Lastly I would do a firmware upgrade as well.

Merry Christmas!!

I'm running the same system in a 4 motor format with the same frame and all the same components. The ESC's are just fine for the motors that you got and 10 x 4.5 are the proper props. You could not swing 12-6 props with those motors. They are not the stock motors that come with an XAircraft. The stock ESC's and motors that come with a XAircraft do not work properly with the DJI WKM, that is why he puts that package together for the WKM. The stock motors and ESC's are really make for the Xaircraft's own controller. I would try to get it flying using only the top 4 motors to begin with and use all stock gain settings on the WKM to start with. Then work on getting the other 4 motors going after it is flying correctly. Then you can work on your gain settings. Right now I would put everything back to default. I'm assuming you are using the X Quad type. If you keep having a problem post you settings here or on the multirotorforums.com - they have a DJI area and a Xaircraft area but the Xaircaft area is more for the stock Xaircraft and controller. Just about everyone on that forum is running at least one DJI WKM.

Little confused on what you where trying to say.
But I did convert to a quad all ready. I purchased The upgraded x650 with AKE motors (quad dancer QD11008) and AKE high speed ESC from cncheli. these combos are put together with components designed to run with the DJI wookong controllers.

I thought you were trying to run 8 motors on the quad. Four on the top and Four on the bottom.

I was!! but for trouble shooting broke it down to a quad for now and reset software for quad. I got about 6-7 min flight time in octo. see what I get with quad. pluse I run JR so no sbus option. with octo can not run gible. so possibly keeping it quad if all works out. just think im half way there to my next quad parts wise.

Can you take a few shots of your quad along with the GPS antenna and the imu, etc and post them in your gallery. Sometimes it helps to see what your trying to help someone with.

I would also be curious to see a copy of your Mounting Screen or the numbers you have plugged in there. Also what is checked on ur motor screen and the Auto Pilot Screen should probably be set to default for now.

I hope every one had a great and safe new year!!
Well holidays have past and back to my testing and e-mailing on the DJI x650combo, to correct and get to the bottom of this quad issue. I feel as though the stability and position hold should be resolved by end of this year.

DJI multi issue update

I had it work correctly yestrerday when I went to vidio the problem for erik sun.(DJI ) with Gary's esc's installed it worked correct for three RTH and position hold.I changed back to my esc's to try.And for two batteries it flew good? Today went again to fly with my esc's again' And it flew like it did with problems. lights and clockwise circles. driving me crazy. well back to Garys esc's and same settings for tomorrow. flights.
I need to thank Gary for his help!!! If not for him and his loaner esc's I would Feel compleetly alone trying to find the root cuase of this problem And I think we are close. I will keep posting updates

update. 1/12/12

Hi guys What should my voltage be?

just going over the power system. what voltage should be going into the mc from the pmu/pw wire out,I tested with my battery. My battery is 3s at 12.5 volts.

I checked with 4 cell as well. 16.75v charge. voltage on pw out to mc input did not change. its the same with 3s and 4s. 6v

my readings. on pw out, mc input
brown and red. 6v
brown and the rest 2.28 v

led port of gps wire is the same

from manual

ƒÞ PWPort
This port provides power to whole WKM system (MC, IMU, GPS, LED) which does notneed to get power from any 3-pinservoport. The output voltage is 12.6V If inputvoltage from battery is higherthan 13V; the output voltage will follow the change of input voltage (0.4V lower than it) If input voltage from battery is lower than 13V. Its maximum output current is 2A.

added 1/12/12
Ok final find. dji pw port was 12v on older generation pmu's. now there all 6v on pw lead. shure would have liked to test the 12v one.
