I think the prototype was based like that but the final product seems to come with its own that is pretty much the same as the inspire from what I can tell
yeah it's an x3 camera & x3 gimbal,
so they added a handle & phone mount (& an extra $100 to the price).
if they offered the handle by itself it'd be cool -- it says it works with x3 & x5 cams -- maybe in the future....
The results are definitely impressive though but I suspect it will take a fair bit of practice to keep the camera focused right where you want as you move it around. The videos I've seen of it seem to show it staying in one plane as you move it around so I guess you have to keep pointing on the iPhone where you want it to look ?
