Styro everywhere.I used a home made hot wire foam cutter from instructables.com.very cheap to make and it works great.Correct on the tubing,its choked down on the mouth end to two copper tubes that point over his tongue.The single motor is from eBay,it has two output shafts so one opens the mouth and the other raises his wings,there is a micro switch in the mouth that trips the LEDs.As for skin Im thinking just mache after I sculpt some more and use some clay for defination.His eyes are ping-pong balls(not in yet) that will be green LEDs and be on all the time.Thanks for everyones support.Its my first attempt.
