i was just looking at the hands of my optimus primal and i noticed that the furry hands went with the robot mode. i figured, ill just switch out the hands..... that didnt work. when i did that i realized the hand switching mechanism didnt work at all. turns out my arms were completely backwards. unfortunately the arms are not on ball joints. i was able to fix it no problem and everything is fine now! i was just wondering if i got a shitty one or if this was a wide know occurrence?
