Heads up for others who already have Iris units and have ordered the Iris Gimbal Kit from 3DR. They are shipping the gimbal kits without the long legs, mounting hardware for the Iris, any documentation or instructions.
One screw and nut combination has a brass fitting, but the other does not. Perhaps that is another oversight.
Thank you for bringing this to our attention. We will ship the remaining components of the kit to you as soon as they become available. Instructions for connecting the gimbal to IRIS will be posted to 3dr.com/iris/info. Our apologies for the inconvenience, and thank you for your support.
