Cool could you make instructions.¦]
Basically, all you need to know about is the catch for the "rocket launcher" triggers, and the clutch gear. The catch enables the triggers to be pulled back while the launchers are being rotated. The clutch gear enables the actual trigger you pull to be pushed back forward. I won't give you the entire instructions, first of all because I don't have them (you could look at the pics, though) and second of all because engineering is the most fulfilling thing you could do by yourself, and it would be kinda' mean to deprive you of that. So just get your "rocket launchers" some gears, a few brick/Technic hybrid elements and get to work!
