Seaplane is an ultimate flying transport that can move in the skies, on the water, and on the ground. Controls are as you expect on this kind of addons - look up to ascend, and look down to descent the plane. The moving speed is relatively fast - it is faster than any horse for as I know. You don't need to fuel a plane or tame it, and it can seat up to 3 people. If you're looking for a fast way of traveling - get a Seaplane addon for MCPE, and you'll never be disappointed.
