Googled, I made this boat out of Defender Spiderman plane parts, after I realized how lame that plane was. The boat is also lame, but fun. too much throttle and it will lift on one side which noses in the other. If I were to do it again I would definitely use two or four amos or pontoons, the best setup might be 4 long slender pontoons, above and on the water, such that if you roll it your electronics don't get soaked. This boat is fun to scoot along the lakeshore. I had originally hoped to put my waterproof digital camera on it and take some movies with it but it only has about 2 minutes of flight time. You can see that the props were not pushers, so I had to put them on the pillars.
