ive orderd to lots of parts from the us and the one from tower hobbies i used ups and got hit with $120 for tax when it got here (for $250 worth??) but i got $300 worth of batteries from axxis racing and sent them bye normaly post and didnt get any tax so i think that u can avoid tax if u dont send bye ups or courier! correct me if im wrong??
also my dad has orderd $1200 worth in the part and got hit with very little tax. once again he used normal postal service.
