Also are there any differences between the US and UK version except for the crystal changing.
I'm sure you've already thought of the fact that the US version will be on 72mhz whereas we use 35mhz here in the UK.
Worth checking about servicing as well. Last I heard Ripmax (UK Futaba agents) wouldn't touch grey imports (IE one bought elsewhere and not through them), this might have changed.
