Friends..it was my long dream to complete aN RNLI Life Boat..all of my efforts to complete this boat is dedicated to all brave Men and Women, who serving the RNLI..and i am bowing in front of them all, for the bravery and dedication..to save lives, while risking their own life..
as usual, i started with thermocol sheets..she spans about 3 feet..
the motor was scraped, and reworked for 6 volts..it runs about 5000 RPM..
you can see a simple piece of PVC pipe, over the prop made of aluminum lid, is a simple nozzle, to avoid any side thrust wasting..it gave me even more than 20% battery life..
