Rustyrivet / ETpilot and others here ,i put my trainers on floats long ago and enjoy water flying all summer now with a few trips to the flying field . After learning how to build from plans and cutting my own kit parts out its changed my hobby for the better in my eyes. I enjoy the building of anything as much as flying them now and always will . Here are almost 7000 free for the downloading plans hope you enjoy this hobby like i have for 40 + years ,
