I am new to the forum, please excuse me if there has been a thread on this topic in the past. I have not fully read the P1 history discussions.. My reference to AUTONOMOUS GIMBALS refers to units that require no input from the flight platform, hence no wiring to the drone. Input can be preset prior to launch or from the operator via, radio signal, Bluetooth or other wireless links (IR?) With many gimbals now off the shelf for earthbound use, requiring nothing more than secure the camera and go (autonomous), are there any that are small enough to be mounted to a Phantom 1 requiring no electrical connection to the platform itself? Irregardless of the effects of flight time...even minus a tilt 3rd axis, does such an animal exist? At current, my interest is purely focused on maintaining a level horizon, even if I need to preset that before flight, during a turn or change of direction.
