When I was running the Tarot 2D with the original phantom dji transmitter everything was going great. I swithed over to a Futaba T8J and I set up the tilt with channel 5, the VR knob. Problem is it is not acting like the phantom transmitter. When I turn the know down, it pans all the way. The more I turn it, the faster it goes. This happens in either direction. To get it to stop you have to find and backup to a very shallow sweet spot, almost impossible to find. Is there a way to set this up so when you stop turning the know, the panning up or down will stop?
