I know Phantom owners are binding their phantoms to Futaba radios etc... I realize that some people are installing a self centering throttle stick to mimic the DJI stock transmitter. Can you change how the throttle operates? In other words, like a conventional RC. all the way down is zero. all the way up is full throttle versus the stock transmitter... center is cruise control: above center is increase throttle ... below center is decreasing throttle. If so... how does GPS hold or att hold work?
