So this is what I call a "Roamer," why? Because it can roam around. I want to make like a boat or something and put on of these guys on it so i can explore it. Now, onto the instructions! First off, save the dissassembled one as a sub assembly. It wont have the cockpit until step 2. Once you save it, place it. Then, Step 2, add a cockpit like seen here. Then, Step 3, move the detacher to the back of the cockpit, so it lines up with the ground. Once you spawn it in, press AG1 to detach the engine. Use pitch up to go forward, pitch down to go back. Roll left makes the arms go back, roll right goes forward. Yaw turns this thing very fast. Enjoy! ;)
