Noticed after the first flight that the rubber tread on my landing gear, on one side, was hanging down about 2 inches. it easily snapped back into place and I did not think any more about it. Then in subsequent days, it happened twice more. Each time I pushed it pack into place and it looked and felt OK. Checked after each flight and it was still holding on just great! Had a DUH moment, I figured out what was causing the problem! Every time I take it out of the DJI shipping box, it pulls that piece of rubber off about 2 inches worth! Must be a bit to tight as it gets pushed down into the box. So if you are having this problem, that is what is causing it to happen!
