so, the ice base destroys anything it can lock onto. how do we defeat it? perhaps hiding the cockpit out of sight while the gun can still shoot? that's exactly what i did here. climb the mountains, find a good spot like shown in the picture and fire! The controls are rather simple. The reason it's "Fine-tuned" is because of its dual rotator system. ag 1 enables the standard rotators. (Controlled with VTOL and trim) use these to aim the gun somewhat near the target. then dissable ag 1 and activate ag 2. this activates the secondary rotators and gives you a much smaller window to aim, making the gun much slower and easier to aim. throttle controls the pistons that immobilize your vehicle for better aim. good luck and have fun! Finally take revenge on that darned thing for all the times it's killed you!
