Anyone else notice a rattle when hand spinning the props on the i2? 3 of mine do and the other does not and feels tighter than the other 3. No rattle without props from motor or mounts. Anyone??? Also, my landing gear 3 times now stopped midway down and refused to go all the way down. I had to disconnect the camera during flight to land. Yesterday it came down on the camera. My dealer just told me to contact dji even though i am in my return or exchange period. I just got it Wednesday and don't feel I should have to deal with dji until after this return period.
