RE: Changing Modes
If its the JR manual for the 2610 it is because in Japan they do not have user stick mode change enabled, likewise in the USA the manual is written by Horizon, again the system (6102) does not have user stick mode change enabled.
This is because the local requirements are for analogue trim on the throttle. This therefore negates the ability to change stick modes.
Stick mode change is usually found on the export versions (indicated by the ES suffix on the NET code)
