I am a new tau player. My last army was Eldar and i had all my tanks' weapons magnetized so i could swap them out. I also had parts of the actual tanks modular so i could swap them out making a falcon a fire prism and such. I hope to do the same with the tau if possible. the devilfish and the hammerhead seem to use the same body. The Skyray looks like it might too. Are there any guides out there for doing this? Any place i can see what the Skyray sprue looks like so i can come up with my own idea?
