ken - I also have the BooBox system and love them. I have contacted Travis from Fright Ideas concerning the servo's and he stated that that feature hasnt been completly set up in the firmware yet. He was working on getting it up. I will contact him again to see if it will be done soon. What i did to get around that for the time being was purchase a medusa DMX board from Hook on Scares. Planning on running the servos with it connected to the BooBox thru the DMX. Havnt got the prop built yet but going to start this weekend on it.
