No really. I bought a new Phantom 2 and the dealer and box say it is an H4-3D gimbal. However, when I click on the upgrade tab the gimbal comes up as an H3-3D, not H4-3D.
I might be wrong, but i think i read somewhere that the H4-3D is just like the H3-3D, but the H4 is specially designed to go with the Hero 4 Black camera. And that the specs are the same, thats why it says H3-3D in the upgrade. I just upgraded my P2 with H4-3D and i also got the H3-3D in the menu.
Thanks for the replies. Millmaker has it right. I was referring to the firmware upgrade. The dealer told me the H4-3D handles jello much better which is why i went with it. I was doing test flights over water yesterday, which can give heavy jello, and so far it is working and i am happy. I just wanted to make sure i didn't get scammed on the gimbal.
