The Caspian Sea Monster sea plane project & Gaint wingspan glider designs

The recent updates/upgrade on the glider where either the tail or wing, mainly the tail configurations like a T tail, V tail, and standard tail. The last modified thing was the wing placement for less wing flex and better flight quality.

The Caspain Sea Monster sea plane, a 3ft long fuse, one foot wing (front to back) angled at 15° for a up-lifting airfoil. If you can notice, it also has water steps underneath for skipping across water/air smoothly, I made this well enough to fly over land and water with a single prop or a 30-40mm EDF, mounted on top the fuse, 3 inches from the wing (front edge). This should holpfully fly like the original Caspain Sea Monster.

your designs look so cool, i can't wait to see one fly! i am just a beginner, and can't build anything without instructions and parts specifications. build videos are a great help to me.

By the way, Ekranoplans are designed to fly over water and if the trapped ground effects (angle of wing determine it) are not trapped properly, you will never get enough lift to get on step, no less fly.
What about motor/prop?, which has to overcome drag to get on step, then break free to get airborne? Did you figure out that?

If thats the case I recommend watching Julius perdana on YouTube he makes amazing foam board airplanes with instructions and free plans !
