Interesting, fixed line might be the way to go.

Desperately trying to get hold of one, but can't find anyone with stock :( Ben

Hello To fill in the time gap until my zenmuse is repaired (and to possibly replace it) Im going to build a brushless unit. Couple of really quick questions though.. 1) There seem to be two styles of motor, disc and 'normal outrunner' This...

Hello This is a known problem with a certain batch of WKMs. Please contact your dealer for replacement. http://www.multirotorforums.com/showthread.php?8852-Wookong-Woes Thread on it above. I had my IMU replaced and problem gone.

Hello all Just thinking, could you not use a small quad just set to hover at say 400ft above you to act as a fpv relay to your main uav? This would mean much greater LOS ranges without having to worry about stronger tx anyone tried it? Ben

yeah they fail to mention how the Movi gets rid of lateral up and down movement, surely one of the biggest effects of hand held!?

So guys I'm going to attempt to fix this myself. Here is a video of the problem http://www.youtube.com/watch?v=s42Ol80txVU You will notice 2 things. 1) When it comes to a 'level' on calibration, its not level its about 20 degrees off in both roll and pitch. 2) its spins out of control in...

Great news perhaps DJI europe can help me out too?? I fear if this thing goes back to china I may never see it again!

Yep good shout but have checked they are all seated correctly. Keep the suggestions coming though!!!

this sounds like it should be a recall to me. Failed s800 motor has just cost me a zenmuse :(

I am very tempted to just order a new encoder from farnell and give it a bash. Does anyone have high level schematic for zenmuse? And/or does anyone have a zen and a logic level analyser so I can check a couple of things against mine?

Na they aint stepper motors, brushless. I might try knocking up a stepper motor solution to try, got a few high resolution ones kicking about. Advantage with them is lots of torque, but I doubt it will be that smooth. B

Balls, looks like its got to go back to China, I suspect I might see it again sometime next year :(

This one I heard...

stepper motor gimbals, are there such things?

Hello all I have 8x unused AXI 2217/20. Superb and super smooth as you would expect form AXI. £15 a pop or £100 for the lot

Yeah tried that, I also disconnected the Encoder from the Roll axis, this prevents the roll spinning, so I suspect this is where one of the problems lie (if not the only one). Those encoders are pretty delicate and i think some grit got in there.

Any news Geoff? Ben

similar, but mine just keeps spinning exponentially faster.

Thank you Geoff. I've had a closer inspection this evening and it seem that it's the roll axis that has the problem. On power up it starts normal calibration (you think everything is ok), and the after about 5 seconds it just starts spinning faster and faster in roll. Ben
