Hi, just to share what I've done to my Airachnid. I replaced the arms with FE Arcee's and added double ball joint neck. Though the alternate mode still kinda sucks but the figure can be transformed between modes without need of dismantle anything. I am still looking out for something to cover the upper/lower arms wishing that it would look less hideous in alternate mode. Please feel free to give your suggestions and comments, thank you! Sorry for the blurry pictures.
