Just bought my 4th copy of this battlepack and used parts from two of them to make this AT-RT and tri-fighter. I got the instructions from online but modified them slightly to be more accurate since I have a lot of extra parts from not building any of the ugly ass official speeders. I still have a lot of extra parts from this endeavor, but am not creative enough to come up with much else with this set of parts. The best I could come up with was a grenade backpack and grenade launcher for one of the B1 droids.
