Hi everyone!
I've been registered as a member here since 2004 but hadn't been active since this is my first post in i think... 15 years? (holy ****).

I've purchased an MP36 Masterpiece Megatron and i'm very happy with it. But one leg joint is beginning to get a little loose. not as thight as it should be. I was wondering if anyone here has experience in doing repairs i'm very reluctant to start unscrewing stuff so i want to be sure not to do any more damage by trying to repair or thighten stuff.

Thanks!
In the red circle is the joint i'm talking about.

mmmh need to check my copy, but a solution could be to tighten the screws of the leg near the joint.
