Just thought I would share my Arducopter mode setup on my new Futaba T8J, as this can be a bit of a headache for newcomers. The new T8J radio is my new favorite transmitter. It offers a lot of features that was only offered on the 8FG, but at a fraction of the price. It doesn't utilize FASST, rather S-FHSS. With the settings pictured you can get all six flight modes on two toggles.
First I set my three position toggle to switch C and the two position toggle to switch D, which is changed in the AUX-CHAN menu. Next I changed my end points on channel five to those pictured below. Lastly I setup the program mix (under P.MIX1-6 in the 8J menu). Just dial in the values pictured below. Maybe this will be of use.
