Talking about Apaches in a Chinook thread could be considered fightin' talk!
Thanks to Bear for pointing out that I'd missed the starter key! I've also been experimenting with cubemaps on toggle switches.
The cubemapped mirrors are also in place. They work as expected (as you move your head the 'reflection' in the mirror changes to reflect your viewing angle). With trackIR it should look quite natural.

Cheers
