arduino with 3,3v and 8 mhz

Hello everybody,

Is it possible to use an arduino 3,3V 8mhz for the wii copter ?

Im interested too, i've got an Arduino FIO ATmega328P 8Mhz, will work?

I am not sure if this information would be helpful but seems relevant. Ladyada claims, arduino might run at 16Mhz @ 3.3v:

She mentioned at the end of the post:
"That's it! You are now 3.3V powered. This is a little lower than the power/frequency specification for the AVR chips since they ought to have about 3.6V to run 16Mhz but its probably not going to be an issue since AVRs can be overclocked a little."

So if you guys can just replace the 8Mhz crystal with a 16Mhz one, seems like you are good to go? I haven't tested any of this though.
