It was good service, I thought when after a few weeks I received a replacement drone, but the joy was short-lived.
Unwrapped the replacement drone Firmware updates went without problems, but on the first attempt to take off it stopped with the error message 'motor stuck'
The right front motor was not only a little resistant, but hard to rotate by hand. Inspected the engine inside with a micro camera, but no fragments inside it. So I searched a bit on forums and yt, and found that others have had the same problem with ball bearings and hardened grease inside the bearing. The solution was lubrication of the ball bearing at the top of the motor
Didn't want to send the drone off for service again so thought I'd try this solution.
So I dripped a small drop of special oil for small ball bearings mixed with isopropanol on the top/edge of the ball bearing and watched it soak in
And it worked, but only after an hour had the grease dissolved so it was easy to rotate. Tested the drone and everything worked as it should.
I then contacted Dji and asked if this was an ok procedure, but no they did not agree to lubricate the ball bearing.
They wanted the drone in for service
So then it was time to send it in for repair again.
10 days later I get a call from the Dji repairman, who wonders what is wrong with the drone, because he can't find any faults.
I explain to him what was wrong and what I have done to correct the problem, which he confirms is perfectly fine to do.
So the drone was then sent back to me.
Today I received the drone, happy and satisfied I unpack the drone.
In the box was a loose drone upside down without any kind of stuffing around it, without camera protection, which was on the side of the drone and without the foam rubber in place behind the gimball.
Fortunately, this seems to have gone well
This is too bad, and I doubt that my next purchase will be a Dji drone. |
