@CarolineTyler you seem pretty knowledgeable so I am hoping you can help me. Or anyone else. I have a number of transmitter but I am hoping to use the T8SG for my small drones, UMX park fliers and oddball projects. It is nice, small and easy to carry over to the park. I am converting a cheap boat that had dual jet motors from the crappy chinese transmitter it was sold with. I have two brushless ESC's and a 3 channel receiver in it. On my Spektrum or Taranis I think this would be easier but I just want differential thrust on the throttle stick. Using rudder(yaw) for steering. I have throttle working on channel 1 and 2 so I can get it to go in a straight line. Now I just want to mix rudder into those inputs. I haven't found a video on how to do that and the way deviation works hasn't clicked in my brain yet.
