How to Make a dragonfly rubber band powered

[@wafikiri_]

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!

Try to replace the wings and tail with lighter materials...btw, nice work! keep it up 👍 thanks 4 sharing bro #ProTekGuy

[@princeprajapati6738]

Bahut sandar mechanism but i think you need to use poly wing...!

[@ishwarsinghjangir3091]

Nice 👍👍

[@pachanauta7083]

i think wings are not making the wright movement, with plastic bag will change

[@wafikiri_]

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."

[@marlinmixon3004]

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.

Excellent boss keep it up

[@ajayinventions5053]

Congratulations bro for 25k 🌹🌹🌹

[@robertrobert5188]

any reason why the holes in the rear wing axis support is drilled vertically while the front are horizontal? I see none.

[@aidanwelly]

Nice work, i like it.

Great work...tanks for sharing👍

Nice bro 🙂

[@maurosouza3494]

Legal muito legal ,mas no palito se picolé não precisa de medidas ? Só nas outras peças?

[@prashantjangid7380]

keep it up 🔥🔥🔥 simply amazing!!

[@DeathsPit00]

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

Try try but don't cry My first rubber band ornithopter did not fly but the second ornithopter can fly

[@3JWings]

Yes failure is most important because we learn from it

[@dogshortvideo3612]

Yes

Try to make the wing plastic

[@григорийгришин-ъ9щ]

Привет! Скажи пожалуйста какой клей нужен? Я хочу тоже такой собрать! Спасибо за видео!

Bro make a rc dragonfly🙏

[@rodrigocastillo407]

Necesita más fuerza el diseño es perfecto, necesita un motor

[@sagar48780]

Its heavy on front

[@annijeoma1284]

The reason is because of it too heavy

[@d4ro]

the wing material is too heavy

[@григорийгришин-ъ9щ]

И расскажи какие материалы.
