>>8588350As someone who owns it I can say it's really stable for a moc.
Despite not having pistons or more friction in the legs he stands quite well, not counting the hammer of course.
The thing about the torso is that some piece are attached in a way to cover the empty spaces but they tend to be loose. Pic related is an example, that Metru shoulder armor is not that secure there.
The head is also not that well built as it tends to be quite wobbly when moving it.
Other than the arms and heavy hammer is not that flawed. Hell, even the rubbers in the chest and thighs work well and help at covering the body.
