This is one fun boat. i’m floored with how fast this moves with a 3s lipo. this was well worth adding to any rc collection. i will tell you my boys were excited to see this boat fly out of the water when i punched it.. Design and development. the rc-3 seabee was designed by percival hopkins "spence" spencer, an aviation pioneer who built his first hang glider in april 1911. at the time, he was 17 years old and constructed it from plans he found in a popular mechanics magazine. on may 15, 1914, spencer made his first powered flight in a curtiss flying boat. in 1937, he joined sikorsky engineer vincent a. This 1/4-scale fokker e.v., designed by david johnson (plan no. x0305a), is a great project for anyone who wants a ww i fighter but doesn’t want the hassle of building two wings..
