Alright, I think we've officially created the no. 1 reference for Masterpiece Soundwave finger popping off in the inter-webs! Sigh... bummer about this, more a bummer if it affects both sides of your toy.
After my attempted fix, I think I can categorically say it at least can point straight without popping off the joint, although definitely not tight enough to manipulate the finger back and forth just using the tip.
Haha! Well, if you're referring to the setup using the 'sensor' thing to join the piledrivers in tandem to the port on the side, I think that's meant to emulate the link cable from that scene in the '86 movie!
Here's my take - it's meant to stay on the arms after transformation, attaching to the rear of the player:
The piledrivers are flush with the tabletop this way, although it's hardly 'storage'! Remember, you saw it here first - another WORLD PREMIERE courtesy from us folks down-under!![]()
