SInce I build mostly radio control ships, I include the cost of the radio gear and special gear for that particular model. $1100+ (kit, radio gear, watertight cylinder, ballast & flotation) to e/c the Moebius SEAVIEW, Scale Shipyard 1:72 scale USS SKIPJACK (built in 2000), Thor Design 1:96 scale USS PERMIT, and Scale Shipyard 1:96 scale USS HAMMERHEAD (SS-364). About $1000 for a Tamiya Knight Hauler, Multi Function Unit (speed control, sound, lights, etc.), aftermarket rims and shocks. When I bought the Knight Hauler and accessories, I was working at the LHS, and the cost is with my employee discount.
