@@inakakoubouKANAI Thank you for documenting and showing your process for making these creations. You have done lots of research and testing! There are some amazing learnings you could write out of all the building crafting and flying you have done. Praise!!!
The thermal gliding was so beautiful, and fun too! You have achieved such a mastery over time that it almost looks easy, with success without much adjustments.
Beautiful! At some point in their development early aviation engineers dropped the idea of bird-like wings and designs - they just couldn't make it work with the materials and the knowledge of the time. So they resorted to the stick fuselage, simplified wings and control surfaces as we know it today as a standard design. You, however, made the true dream come to life.
Beautiful work, very creative. I like how you designed the control authority system. The gull is a good choice for this type of design IMHO. Thank you from Canada!
Amazing, I'm positively stunned. I love this hobby and watching people make these things... What made my jaw drop was that you just threw it and it flew perfectly, no trim needed!!! Truly amazing. Great job, earned a subscriptor, greetings from Spain.
Nice and beautiful design, using a ducted fan is a great idea to hide the engine and the description and methods for building you made are very precise
Beautiful craftsmanship, and innovative manufacturing techniques! I came across this video after searching for cricut or scanncut machines, due to the functionality and flexibility with low cost I believe that they are ideal for 4D, or origami models including paper, foam, balsa wood, card stock, and even aluminum from cans! These machines can be purchased used at reasonable prices as well
Congrats for your great results ! Could you please explain more in detail how the two tail surfaces move in relation to aileron and flaps ? Many thanks from Italy !
This is a great design. I'm surpised none of the Model Manufacturer have not approached you to produce your work. Do you have your plans available for sale? Please keep developing your wonderful designs.
Wow, what an amazing job you did, man, congratulations, excellent design and engineering, I wonder if a bigger and scale seagull like that could be piloted by someone, who knows if that will be your new project hehehe, congrats again, keep it up, i suscribe now 😃😉
The presentation is highly scientific yet economical (without style of self-indulgent babbling) so A+ A+A+. I'm noting that when you need to get lift quickly, the inlet design is giving you a downward suction force on the head, so this is countering lift. Do I see a nifty solution? It will change the appearance and maybe this is not worth the trouble. I guess drop the tail to increase head-up as needed. Nice guitar added in there. Truly A+A+A video.
I tried to draw air from the top and close the lid when not in use, but I gave up because it didn't seem to be the design I wanted. I'd like to try new mechanisms as my skills improve.
beautiful 'bird', seems to fly very smoothly, good response to controls...i guess, with a wing more like albatross, its thermal gliding would be even better... sumimassen...I've tried to think of how the motor/propeller could be quieter..normally bigger diameter and slower, but i wonder if you could use a larger 'impeller' type fan, that would be flat, maybe even be part of the 'shoulder's part of the wing...maybe a larger fan could be tilted, so that it is not so tall, maybe lower efficiency of ducting, but maybe higher efficiency blades, with noise-reducing 'feathered' edges...if the fan is located near the front of the wings, that is where the bird body is naturally the biggest, with wing muscles, so you have be biggest area for the fan...can the fan "duct"be removed, and the shape built into balsa, or carbon fibre, maybe saving some weight, and giving you some more design flexibility? just some crazy ideas..could you make the outer part of the wings, like the primaries of a bird, mounted a bit flexibly to the main wing, and tapered to very thin & light, and put sensors at the join part to detect the 'loading' on the outer wing; in a soaring bird, they detect the 'edge' of updrafts, and turn toward the updraft. you could, maybe, make something like that into the control software, so, if the motor is off, sand soaring, the bird would automatically "tend"to turn into the thermal, or, at least, give you an indication that it "feels" a differential updraft? in any case, on some other designs, i have seen that the builders do not reduce the stiffness of the wing as you go out toward the tip, so the stiffness is more than needed, and the weight is more than necessary?
Thank you for your comment. How to create flexible wings has always been a challenge for me. I also think that deciding what sensors to use and how to use them is an important issue.
Beautiful whimsical bird model. How does it maintain such good directional stability without a vertical fin? Do you have gyro controlled wingtip spoilers?
Congratulations, excellent work. Could you share your plan in pdf format with a 1:1 scale. to be able to print. Thank you very much, greetings from Mexico🙂
