I was in my 40's. I filled out the paperwork and took it in to the manager. He refused to sign. His words: "I'd lose a good layout designer and get a bad engineer". Fuck him. You pursue your dreams. I didn't, and now I sit around watching youtube videos.

Hey nice video. In the pic of the 3 pelicans, they are actually flying like most soaring birds and open ocean long distance sea birds, with the most lift happening the closer in you get to their shoulders, where they have fore and aft concave, lateral concave, as well as top view template concave. Just a massive inner section of lift, joining in with the body at the shoulders, with a massive refined fillet blending it all together. That way the lift is were it takes the leverage of the birds muscles, way less energy and effort to keep its self in flight for long periods of time and flight. Next the pelicans in the photo aren't that different in height. The one on the right is just much closer to the camera. But all three of them are actually surfing that ocean wave. So let's say, in dead wind, surfzone waves like this one, are traveling somewhere around 5mph and push an air wave above them, which give the sea birds a form of means of travel. They combine that with the added help of ground effect the closer they get to the ocean surface. They also alternate the concave in their wing span from that pocket near their shoulders, all the way out to their wing tips depending on the needed articulation to stay in trim to the air wave. Those tips are actually accelerating the air flow as those last few feathers flex. Like when you kick with swim fins. The tips of the fins are bending into the water flow and allowing you to thrust water backward and yourself forward. Albatross use their wing tips to actually barely touch the wave going extremely fast in air surfing the open ocean swells. And the prandtl theory says that tip vortex can either be drag or acceleration on a manmade plane, depending on the design of the wing tip. Next. On your model, the twin vertical stabilizers can have an extremely positive added behavioral characteristic if you give each one about 2 to 3 degrees of toe-in towards the nose. It creates an auto correct feature to the performance characteristics. I'm at 5:20 now I'm going to watch the rest of the vid. Also on those hydrofoil speed boats. Their engines need to be mounted in the front of the boat, like a common prop plane. The props can be in the back, but all that weight in the motor needs to be in front. Wow, great work. Excellent flight

Awesome design she flies like a dream! Did anyone else see the fish jump at 8:14

Great job, kudos. Love it, totally stable in flight, and scoots well. Looks like a joy to fly.

Very good job ! Thoughts to go further : Real Ekranoplans do not fly high altitude because their aim is to capture best performance due to ground effect. To capture that performance they have small wings that do not enable them to fly high altitude. If your prototype can fly high altitude, then it is not an Ekranoplan, it is just a plane that flies low and benefits from ground effect. To make a real Ekranoplan, you need to reduce and optimise wing size so that the prototype has the best possible ratio speed-range/energy. A way to achieve this simply with your prototype is just to load it more and more until it will be unable to reach above ground effect altitude. And then find at which ground effect altitude it has the best speed-range versus different loads.

A uniform planet is an awesome adventure for this particular technology.

Bravo, there are a lot of WIG builders but few succeed. What you have created is basically a Bierev VVA 14, with the area redistributed in a higher aspect ratio format. I know it doesnt look a lot like it, but this is how the VVA 14 was planned out. You could just as easily put tails on booms, as is popular with Russian designers to this day. As with all these things power and the combined wing aspect ratio dominates the point where the vehicle takes off and climbs out. Clearly to go fast over water, the math needs to satisfy those cardinal points. Otherwise you climb out quicker than intended. The other thing was motors. Forward motors are usually increase dynamic stability, and allow ram air to get under the wing and get the machine to unstick from the water. This especially if the engines can be canted to direct thrust beneath the wing almost entirely. It is important a feature on full scale because the power and RPM available is more limited than the model with electric propulsion. Lastly, ailerons should be up only, not opposing up and down as they are on conventional aircraft cheers

this guy knows his stuff and always has good things to watch
