When I initially take off with a fully charged pack, and the landing gear retracts like normal, they Inspire starts to oscillate quickly, the whole air frame shaking. When about half the battery is used, they shaking goes away .. Any idea to what is causing this ?


Here are the videos:

Hey cyber - open a case with DJI support and get your flight logs to them.
Definitely something weird going on from your description.

Can you take a short video and post it up so we can see the behaviour you are describing?
Apart from the shaking / oscillating - is it holding a steady hover and position or wandering all over the place?
When the battery level drops down and the symptom recedes, are flight responses normal?

Bad balance or damaged props will cause shaking but of course that would be happening all the time and not dependent upon charge level.
The issue sounds electronic from your brief description. The best bet is to get the flight logs to DJI for review.

Hi , Cyber
This is really strange , would you please post a video of that ? Does that appears everytime ?

Initially I thought it was the balance on the props, so I changed them out and switched them around. Same issue.  Also to note - when the landing gear is down, the shaking goes away.  I'll post a link to the videos here soon when I get to the office.  Thanks guys ! It's a shame there are so many issues with the batteries from what I hear ..
