I just have bought a Kopaka a couple of weeks ago, and for some reason, his right spear arm keeps falling, even though I built it right.
I went on YouTube and saw Jangbrick's video on Kopaka, and he managed to extend his Kopaka's arm completely without it falling.
I need advice on how to make the right arm stronger.
If I discover anything, I'll help those who ask.
