The model being used is a 1/35 British Challenger 2. The alternators used are two sideswipes and Hounds arms. There's a whole whack of armour to cover the sides but at this point, much of it is taped and unfinished. To transform, flip the turret up and ahead. Separate the legs as Sideswipes do. Flip center tracks around to back. They are mounted on Sideswipes old forearms and hands allowing them to flip and swivel. Drop shoulders. Hounds arms will be hidden under the armour and half of the wheel in the center track will be cut off to allow them to hide. Flip chest and head down. The abdomen is gonna have a bunch of details added and will set the proportions better. The tracks will not turn but be glued in place, it's all a d00d can do when working off of the G1 show. At this point, I've got about 8 hours into it. There's a bunch of fillers and details yet to be added as well as a way to combine with the Onslaught MP based on a MP Prime mould.
