The Lynxmotion biped scout torso kit is well designed with straight forward assembly. One thing to take note of is careful removal of the laser cut pieces from the plastic sheets. I recommend using a hobby knife to score the tabs as opposed to a box cutter or other blade you have laying around due to the small clearance between the part and sheet. After scoring the tabs, slightly flexing the part in and out until it pops out of the sheet makes removal easy. Following proper assembly, there is no discernible wobble due to excessive clearance issues between pieces.
