The folding prop is first energized by forward while moving at more than 3 knots I think it was then put into Charge mode. The prop stays out by centrifugal force. The amount of drag is regulated this way I think by only letting the prop come out so far. I am sure that it is not ideal and may not work for running the batteries dead then trying to recharge them in a short time. BUT if you are sailing on a passage it could possibly keep the batteries charged for house use along with solar and wind. As far as the reduction unit goes I would think that if the reduction unit had the prop going slower and the motor going faster it would work in reverse the same way. prop only turns equivalent of 5 knots direct drive but the motor now turns twice as fast giving you a speed of 10 knots equivalent direct drive. I am just speculating here mostly to get dialog. I will have not much to do in the coming future and I can work more on this once I get the boat in the water. This will be something to do while I'm whittling the time away. Making reduction gears and using different motors and such is not really that expensive in the long run. Having a floating lab to test things out will be rather fun and occupying. You have been lots of help and I hope you can continue to be. The more I dig into it the more I learn. This is my way of going to college, a lot cheaper and much more fun. Dan --- On Sat, 8/7/10, Eric <ewdysar@yahoo.
