I took delivery of the latest model of a type V11C U Boat the other day. And although a bit pricey at over £600, you cannot help but admire the attention to detail. It is being sold as 'surface runner' only. But everything is there to turn it into a dynamic dive. All that needs to be done is add the control linkages and servo's and you are away! I am hoping it will submerge rather than sink when I send it out on it's first patrol. At 1390mm long it just fits in the back of my car with the seat down.
