Now that would be cool! Install CO2 operated pellet machine guns in the nose (sort of like at the carnivals where you have to shoot the star out completely). Add video cam with a sight, and we could have some killer dogfights. Though if your cam got shot up, you are screwed.
Being a Navy brat, I lived by the ocean most of my younger years and built many models, wooden ships, etc... I always thought it would be cool to build an aluminum model with running engines and .22 cal main gun turrets and have them remote controlled. I lived in a bayou setting on the gulf so this would have been feasible. Or build a wooden sailing Man O War with .22 cal cannons, the only problem being reload devices. But wood is cheap and would have been great fun, especially with today's cheap electronics. I'd also install a mini flame thrower cannon, so if I got close enough to your ship I could set it afire, hehehehehehe.
