Making of Dragon73 --- Small Dragon fly by AutoPilot

One of my dreams as a child was to have a dragon that could fly like this, it's magical to see it actually flying around. Really incredible job engineering the mechanics too.

[Nigfis]

This has to be among the most beautiful ornithopters there are. The movement of the wings is mesmerising. It 'looks' to handle beautifully too, but that might be the pilot's skills making it look easy. Congratulations from me too Mr Kakuta. Brilliant model engineering.

Flying dragons next to a nuclear plant - that's the beginning of every Japanese Godzilla movie :D

[johnpharis]

This thing is just absolutely amazing.... just the way it moves through the sky looks so anatomically accurate

[speedeemee]

Truly outstanding engineering, artistry, and craftsmanship!

[castronator]

That's simply amazing Mr Kakuta. Congratulations.

Exactly the sounds a baby dragon would make if it was first learning to fly.

[abruptlyblunt]

i wonder if people realize what a remarkable accomplishment this is, others have tried replicating the Mechanism of Flight Flapping without any success, this is truly amazing....

[AlessandroBottoni]

By far the best ornithopter I have ever seen. Really awesome. Congratulations!

[MJPilote]

One of the most interesting RC things I have seen! Very beautiful movement in the air, it has the grace of an animal in motion. Amazing work!

[valveman]

I bet people look twice when they see this dragon coming. Well done!

[raoultheowl]

Bravo! Incredible flying.
I built an ornithopter when i was 14. It flew so well, far better than i would have expected.

It made me aware of an alternative to rubber powered long distance aircraft.

Thank you. I am grateful.

[ukulelefatman]

Fantastic. Great job on construction and design. I hope plans will be available in the future, I'd love to build my own. Thanks for posting your progress!

[ThomasGrillo]

To see a flapping wing design actually working is nothing short of astounding! Thanks for sharing this.

[sohamchandwadkar]

Your design is amazing 👏 I can imagine the effort you put into the gearbox assembly and using the 2212 size motors with it is just genius!!

[robertomighty]

Beautiful design, impressive mathematics, engineering and aeronautics. A dream of flight. Congratulations, Mr. Kakuta

[abesapien]

He needs to fly this straight into a schoolyard and watch all the kids run in panic and joy

[jasmijnariel]

Oh imagine how it would look if it was painted

[Madcrws]

This is fantastic build, excellent model! Frighten every bird around away and started a legend among them to never return to the place mighty flying dragon.
Make one that breathes fire now!

[killbubbatm]

Well done! I'm curious of the power usage vs a traditional prop and flight time etc... looks like a great design though.
