I would like to start by saying hello to every body at the sub committee forum, as i have just joined i built a model submarine 20 years ago it is a 12ft gato weight is 500lbs its a beast it has spent the last 17 years in a trailor and my son said why dont you do some thing with it, what came to mind scrap it but no submarine was full of electronics level control, back hydoplanes very sencertive because of lenght of sub depth control unit, could keep sub at preset depth and would hunt within 15mm to keep it there worked on infa red light sub had four way radio link, video, full telemetry giving data back to bank side padgeing system rc radio control 90 channels was all done 20 years ago. One of the new units to go in sub is low frequency radio link for controlling sub would be interested if anybody else has worked on the same thing because lf is a lot better at getting through water than HF bands plus alot of this is all down to how much RF you can put into antenners other unit i have been working on is on screen display which will overlay on video picture coming back from sub compass headings speed battery voltage and all sorts of other data. To give some idear of size of the sub it takes four 12volt 38 amp hour gel type batterys drive motors for props are washing matchine motors dc 240volts
