Have you attempted to contact SIG? They do ship internationally. The email address is [email protected] When I contacted them for information about a kit they replied within 48 hours.

If you are willing to buy a different brand, Tower Hobbies has Two good trainer choices and one "second plane" that will work with a 46AX (wehich they also sell).
