Hey I don’t believe this. Amazing!!!! Did you know the MOD have built an identical full size of this (oops I shouldn’t say as it’s under the OSA). I saw the trials. It is even powered by rubber bands. Due to continuous cuts in the defence budget they needed a more economical power source. They are working on this revolutionary rubber band winding generator (WBWM). The generator is fueled directly from Westminster and runs on bullshit. In fact there is so much of it they are even exporting it to the EU HQ as well.
Nice model definately the future. Why not build yourself a solar powered stirling engine as a drive source. Very efficient power source, fun to build, and you could sail all day.
