I have designed a motor unit which will drive a fan type <BR>> propeller as an intake this will force water to the rear of the unit<BR>> where it is compressed then it is forced into ducting which will <BR>> take the water to four nozzles on the side of the craft. The nozzles <BR>> are able to turn three hundred and sixty degrees both side are <BR>> independent of one another so rolls will be achievable. The reason <BR>> for a vectored motor is you only need one motor source and one power <BR>> pack this will ease the maintenance and increase the enjoyment of <BR>> using your sub. I am interested in the clubs thought of this kind of <BR>> design.
