Compared to your Hangar 9 and Great Planes ARFs, the World Models instructions seem to be lacking some details (I have only seen the instructions for the Sky Raider Mach I and Mach II). However, if you assembled the Alpha and the Stik by yourself, you probably have plenty of experience to figure out the WM plane. You can always use your existing manuals as reference material since the majority of ARF assembly is pretty similar from one to the next.
