Not me. Just checked that. You're just flicking it and it'll make that sound when it hits the ends.
I am certainly happy though, with the LVII. I thought I would hate it, but the colours came out right to me. Such an awesome scheme, makes me want to mock up a woodland diorama and have them all in battroid and GERWALK modes, looking like they are stalking the enemy.
I love the battroid mode of the 1/48 more than ever now. Just looks so powerful, 1/60 proportions can no way match this.
