I did this a while back. I took some pointers from people who were doing it at the time but couldnt figure out how to attach the tank turret to the back or in jet mode. I eventually sat it down for about a year or so. Accidentally stumbled upon it again at a later time and had an epiphany. I finished it up and never took pics. Here it is for you guys to check out. My "Classics" style Blitzwing....by the way...it IS a lot harder than it looks to build a triple changer. Kudos and many thanks to those that had gone before.
