today i got pcc undertow in the mail. opened him up looked at the box and noticed mine was different. the black part of the thigh is on the inside of the leg. its supposed to be on the outside.. they just needed swapping. took the thigh apart and swapped sides. now its fine also the minicon that came with heavytred has 2 left legs. fist time in hundreds of tfs i've really had a qc problem. im lucky i guess!
