Still continuing my home made devastator. Figuring out exactly how scavenger transforms from just the ONE 30 second transformation scene of devastator .... is tough. But that is precisely why I want to build scavenger and mixmaster first. One thing I have figured out for sure- the shovel are divides into 2 halves which attach to either arm. I hate to sound like a G-whiner, but I must admit, it looks like scavenger's pieces just fly into place. Look at the transformation again : http://www.youtube.com/watch?v=2-Vr05B94Q0 pause from 0:06 to 0:08 .... it looks like the red flaps around his neck, pop out of nowhere !!
