Hi KK, the sub does 'what it says on the box'. It is basic, easy to build entry level submarine and if the instructions are followed it will work with very little trimming or ballasting needed. The video Martin posted doesn't really show the model at its best as it was taken on the prototypes maiden voyage before it was officially released, it still needed a few little bugs ironing out as they say, which has been sorted and it does work fine now. The model in the vid uses a Graupner speed 400 motor driving a 29mm Graupner prop on a standard 7.2v stick pack.
If you want any more information on the model give me a call on 01633 431010 or email
