i think he mean that one... err... the arm joint part which contain the gold sticker need to stick on it.

Use tamiya or mr hobby cement.. should be no problem since i thinm the part is not structural? I mean u probably wont lose mobility even without it

please provide pictures, just saying it break in half dont provide us with any relevant information like where it broke, at what angle, how it broke, whats its condition now, etc etc. There r multiple ways to fix it depending on its condition.

also dont bother using super glue to fix broken parts, its brittle once dry and will eventually break again.

get hobby cement to fix it


for replacement, as I mentioned, Taobao
if language is a barrier, there's other English websites which provide replacement service, albeit much more expensive

I broke the same piece, that piece damn fragile. If you take some super glue or cement u can fix it and it will still be fragile. Luckily after u put it in it doesn't matter alot, as the piece is buried between other pieces. In short, put it in, should still work, worked for me.

Since its hollow, glue it as is will never work since there is no structural support to apply pressure at that angle to squeeze between the 2 halves to provide a strong enough bonding for the cement to work. Attach the joint and maneuver the pieces around till u complete step 4<3> in the instruction manual. B4 u move to step 4<4> put some cement in between the broken pieces and use some binder clip to squeeze the 2 halves together using the joint housing as structural support.

That part is non critical non moving, it will be weaker then it is originally but it should be fine.
U can also recast it with epoxy putty if u want, assuming the same piece on the other arm is intact. Here is a guide on how to do it. This is abit messy but the recast part will be rock solid.
