Have a look at the September 2007 edition of Model Boats, there is an in-depth review of Graupner's Moonraker kit. The review makes the point that as with a lot of the Graupner models, you will need to purchase a lot of additional parts, i.e. three jet propulsion units, three motors, fittings kit, bow thruster, auxiliary and drive batteries, speed controllers etc. All this will cost at least another £500 - £600 so it's not going to be cheap. Nice though!
