OK Bob…. in order…..
Subtle paint job…dark grey fading up to very pale grey on top. Deck camouflaged with light blue (to mimic the blue sky shining off the water surface as seen from a patrol aircraft.
Dont bother with brushless if you have…..4 x 850s!!! way to go…X60 props, yes
Silver/stripes….will make it look like a common speedboat only missing a drivers head on top.. You could paint it white/blue to mingle with the hordes of Faireys on the pond??? good cammo.
Sound…wouldnt bother…do you want steam engine of diesel sounds out of an advanced warship??? Gun sounds not right for a laser/missile based weaponry. Simulated laser lights from the top might be better.
