Scratch Built RC Brushless Outrunner Speed Boat

Here is my boat that I built for my A-level project in DT. The specs are as follows; Motor - 3000kv mystery brushless outrunner Speed Controller - 30A mystery Prop - 26mm Graupner K Hull - 34cm long high impact polystyrene Batteries - 8x NiMH AA cells () I have bought a 20c 1900mah lipo pack which I will try when I get the boat back from the exam board!
