The FT Sea Duck

From Flitetest: "This plane is a twin engine, 3 channel airplane. It is an amazing machine to build and even more fun to FLY! The FT Sea Duck uses differential thrust capabilities which makes maneuvering on the water a breeze!! Another awesome thing that this plane brings with it is, even though it is a sea plane, it flys great from a position on land as well for people who do not live near water or where water is not easily accessible! If you are looking for a FIRST twin engine airplane, you have found it! As you build this plane you will see that it was designed to fit either the B-twin power pack or the C-twin power pack for versatility(recommended)! This plane was engineered to allow for people to be creative and go flying with their transmitters as well as their imaginations to build or fly something they maybe thought was iconic in their own aviation upbringing!"
