These racks are well thought out and use a sling for the yak to fit on.
When your Revo is not on the rack, the arms swing back up out of the way.
If you use them outside, you need to spray some varethane/urethane on them or similiar protective outer covering on them.
The Talic website gives specifics on how far apart to mount the holders.
The maximum girth is 60 inches which should not be a problem when you place the holders at the suggested distance apart.
I had planned to buy a set for my Revo, but I will wait a month until the Revo11 comes out.
