Latch66 - what prop did he us on his OS 91FS?

I'm doing a review on the U-CAN-DO-3D for the RCU Magazine and putting the OS 91FS up front. Once done I'll have lots of pictures in the review and video of this thing doing the 3D routine...you will be able to see right here what it can do. Shooting for November Issue which is about 40 days give or take.
