They are identical...just a marketing thing...
US gets the Magnum version and everyone else the Megatech.
Just beware that Futaba USA will not honor the warrantee if you have the overseas Megatech version. You will have to pay for service and parts. The US version aslo comes with nicds and charger but no servos... some Megatech versions do come with the S9451 digital servos.
