Having read an article about this I must admit the idea is appealing in one way but not in another.Knowing my luck it would sink and would never be found again!!!!
Apparently what they do is put all the electrics in a container that is not only waterproof but ballbearign proof so when it is recovered all they need to do is to tape up the hole with speed tape and away they go again.funny lot some of these modelers,but sounds like good fun
