You'll need to obtain the Helipack upgrade for Clank from Al's Roboshack before you can attempt to get this.
Once you have it, go outside via the entrance that opens once you've got the Helipack and continue through the level until you arrive at the second elevator. Once at the top, turn left onto the ledge and you'll be able to see the statue in front of the Roboshack. Now just simply glide down using the helipack upgrade, land and stand between the legs. Ratchet Poses and you get a trophy.
