That part makes flying much more relaxed. The Hubi stays in fender benders beautifully in the air and the propeller heal.
The processing and the material is good. Worked for me quite a bit to have to compensate for lack of flying skills.
Supplement for a review:
Have received an ordered protective ring today. Have everything exactly respected, as described above and yet came for camera model.
On the front of the packaging and the camera model is displayed and a sticker with the type and barcode of the camera model.
So should have noticed if it were not the back would be with type and barcode from my model.
So lucky to get the right thing.
