Had mine without the extender just Velcro-ed to the Warthog mounting plate. With the extension, it would make the grip way to high.
Now that I've got the new gimbal installed and once I figure out the VKB software, I'll mount my Warthog grip with extension on the Mamba base. I'll have to figure out a way to mount it to the seat frame crossmember. I'll post some pics when I get 'er done.

Currently have the R3volution, had the oZone. If I recall, there was really no difference in the seating arrangement between the two.
