- How to Make a dragonfly rubber band powered
HiiiFriends!
In this video we are going to build a dragonfly special thing is its rubber band powered. Actually it's very old concept for me this type dragonfly I already uploaded on our channel but that model is electric gearbox mini dragonfly.
It's required lots of work on wings because it not able to generate forward thrust. Even it's not glide, so I will update it in future stay tuned with channel.
I hope you like it. If you have any suggestions then comment below & you can dm on instagram.

The lack of forward thrust is due to the wings stiffness. As a wing moves down or up and, the ornithopter, forward, the combined movement of the fore is at a large angle with the longitudinal axis of the ornithopter. If the wing cannot twist around its end-to-end axis, like a flag, its angle of attack is excessive, causing too much drag and too little lift.
If the wing could twist, the drag would be much lower, and the lift much greater and with a forward component when it moves downward. An assimetry is needed when it moves upward, the wing's angle of attack should be close to zero so as not to create too large a reversed lift, but its longitudinal component would still help thrusting forward. It isn't easy to set the downward and upward angles of attack (no geometric references at all, much dependence on vertical and horizontal speeds).
Replace the wings with that of bird feathers cut in half and it should fly forward. You are very creative.
Very nice music!
Nice try..keep it up..
So nic esi aur bhi Sari bdios bheja karo
Vai ma Bangladesh sa hu or ma apki koi vi video miss nahi karta
Super
Very interesting!
Love it and your creativity
Good work 👏 , keep trying👍
天才🎓✨
Try to replace the wings and tail with lighter materials...btw, nice work! keep it up 👍 thanks 4 sharing bro

good working bro keep it up
Bahut sandar mechanism but i think you need to use poly wing...!
Great work bro! Nice try
👍
Congratulations bro for 25k 🌹🌹🌹
Nice try bro. Ho jayega achha idea lagaya hai. Keep up. 👍👌
Necesita más fuerza el diseño es perfecto, necesita un motor
So nice God i dea you very happy 😎😊
Nice
I bet that would fly if you made a membrane wing (plastic wrap wing) and added a tip to your spar so that your wing tip is "L" shaped. This would let the wing create more thrust plus it would also reduce the weight.
nice
Excellent boss keep it up
Great work...tanks for sharing👍
Try to make the wing plastic
Nice work, i like it.
Nice 👍👍
keep it up 🔥🔥🔥 simply amazing!!
i think wings are not making the wright movement, with plastic bag will change
You are totally right, look up my extended comment on the subject, which starts in "The lack of forward thrust is due to wings stiffness."
Looks like you could easily put a propeller on the front behind the crank. That would probably generate the forward thrust you're looking for.
What Is Islam?
Islam is not just another religion.
It is the same message preached by Moses, Jesus and Abraham.
Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
It reminds us that since God created us, no one should be worshipped except God alone.
It also teaches that God is nothing like a human being or like anything that we can imagine.
The concept of God is summarized in the Quran as:
{ “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
Becoming a Muslim is not turning your back to Jesus.
Rather it’s going back to the original teachings of Jesus and obeying him

И расскажи какие материалы.
any reason why the holes in the rear wing axis support is drilled vertically while the front are horizontal? I see none.
Привет! Скажи пожалуйста какой клей нужен? Я хочу тоже такой собрать! Спасибо за видео!
Bro make a rc dragonfly🙏
Try try but don't cry My first rubber band ornithopter did not fly but the second ornithopter can fly
Yes failure is most important because we learn from it
Yes
The reason is because of it too heavy
Legal muito legal ,mas no palito se picolé não precisa de medidas ? Só nas outras peças?
Nice bro 🙂
the wing material is too heavy
Bhai khabi hear mat manana
Thankyou bhai😋😋
Ek dam boring
