Anyway Dudes,
There is a RC sim avilable for non Intel macs and it is free!!
It was put together by the Charles River Radio Club for linux/unix but has been ported to OSX.
Here is the link to the info site wich then links to the download site.

It is really good for the glider guiders with slope & flat field sites.
So give it a whirl, what have you got to lose?
