... Although I'm sure what retailer you bought your Solo from makes a difference.
Yes. Dronefly told me they were only making two shipments. Since Solo shipped, and gimbal is delayed, they were going to wait on my free battery, backpack, props, etc until the gimbal ships.
I tried to talk them out of it and talk sense into them, but couldn't. I cancelled my extra batteries, backpacks, props, and chargers, and ordered from Fry's.
Still getting my free battery from them, as well as gimbal, since I ordered Solo through them. I am sure I won't get free battery Uriel I get the gimbal.
Who you get things from matters.
In general when ordering DJI things it pays to have a dealer between you and the company, to defend your interests. It seems to be the opposite with 3DR.
