Just got a H4-3D (and another Phantom 2) and when I plug it in and open up P2 Assistant (mac), the H4-3D is recognized as an H3-3D IMU on the firmware upgrades page. So the H4-3D is using the exact same hardware as the H3-3D or what's the deal here?

This is normal as H4-3D uses the same GCU as H3-3D

Wasn't there supposed to be the option to change tilt speed on the H4-3D?

no its not. The H4-3D is the exact same thing as the H3-3D only expensive and balanced to the Hero 4 Black.

I have received and tried H4-3D complete NAZA V2, module GPU H-3D is no speed control tilt (tilt). Tilt speed camera as big as in previous versions H3-3D, H3-2D. Are provided for addressing this issue. Announced the release of a new model this problem H4-3D promised to solve.
