I had no trouble with this. Except for the stand, gerwalk mode, the gunpod trigger falling off, and legs not being cluched on to something to keep it in place.
I bought the Roy Branpresto and I was so disappointed with it that I threw it out after so much agony. The Strike Parts would not hold on to the arm, as a matter of fact the arms could not stay together when in fighter mode, and even the strike parts them selves could not stay on the Valk without moving the toy. Even the head fell off, worst $20 I spent, I thought I was getting something good, but no it had to be retarded.
