How is this for a cool hobby??

[Ex-RoNiN]

We built and sail 1/144 scale Radio-Controlled Model Warships from WWI and WWII which are armed with Co2 powered cannon and armoured in thin balsa. These vessels engage each other in combat on ponds across Australia, endeavoring to punch holes in each others hull with their cannon until one of the vessels sinks or flees

How cool does this look?? Would love to get involved with something like that, surely you can substitute airguns for BB gun mechanisms, similarly to what you find on those RC tanks? Does anyone know if this has any followers in the UK? Must take ages to make one of those ships, but the best part is, even though they sink, they have a little "float" which keeps them partially afloat so they can be recovered and reused (I guess electronics are watertight?)
