I've recently bought second hand, but never flown, an aircraft, engine and JR X-378 controls.

The problem is this: I live in Japan, and bought this gear from an Australian who managed to get a special delivery (from the factory here) of the radio controls in the mode used in Australia, whatever that is, 1 or 2. None of the Japanese r/c flyers use this mode, and since I am going to need some help via a buddy box for a while, I need to convert back to the mode used in Japan.

What's involved? Does the Tx need to go back to the factory, or is it a simple matter of changing leads on the back of the controls sticks?

Any help would be appreciated.
