This is my first prototype for this type of engine. You might be wondering , hey what is this engine. This engine uses buoyancy and water to propel itself , how this works is by a buoyant fuselage block hitting water causing a upward force launching the craft into the air. This means that the harder the craft hits the water the more speed it can get.

Prototypes...

I had many prototypes using this engine in various ways, but this one was the most efficient and most controllable of them all. if anyone is interested in one of the other prototypes I can post them.

Controls...
This one was less confusing to control, having less steps.
1 start at a final approach.
2 Aim the craft down towards the water, use the air brakes to change you I'm impact speed.
3 Hit the water and and fly.
4 VTOL for flaps.

This is still a prototype, the only recommendation I have is if you impact the water around 200 miles per hour or more, that you pull up after you hit. Because if you get to high altitude the craft will become uncontrollable

Enjoy :)
