This is the usual AT-AT Walker within the Imperial Walker series besides the ACT, ST and some others. They are commonly seen fighting off the Galactic Rebellion out from the depths of their underground base at the ice cold planet of Hoth. The walking mechanism took over 2 hours to figure out how to make a working walking mechanism I decided to do with out any tutorial which was hard. This contains 200 250.mm laser rounds that shoot at 1 round per second, due to its huge system, 3 Head crewmen at the front head, and some gyroscopes to get the Walker to turn without difficulty, and an extra one on the head to reduce the wobbling of the head. This Imperial addition was impressing to build and create for others to use. sadly, you can't really do the rope trick they doto take AT-AT's down since they have gyroscopes, but target practice is good at least.

Controls
Trim = Walk
Air to Ground = Laser Cannons
Pitch = Vertical head direction
Roll = Horizontal head direction

Procedures to walk
Raise the trim up and the AT AT will jump back a bit, this is normal, then, when you want to walk and your trim is up, quickly decrease the trim to the bottom, then if you want to take another step, do the opposite and quickly increase the trim to the top, and you can repeat increasing and decreasing the trim to get to where you want to go.
