Ornithopter Servo Conversion: Crossbow 2 RC bird flies with servos instead of conventional gearbox

[@cprooney]

Such a nice natural movement. Ive been searching for a 3D printed version of an ornithopter today, and this is the nicest movement ive found all day. Looking forward to seeing more.

[@michaelrtreat]

This is the future of RC aircraft. Really performs like a bird

[@Simon_Rafferty]

I imagine you've figured out that you can lose at least one on the tail servos, leaving just an adjustable elevator - and use differential flap angle between the two wings to give steering. Please continue to make more Ornithopter content - there's not much out there!

[@playframe6231]

Servos is obviously the future for ornithopters. The goal is to actually mimic a brid's dexterity

[@marsmars2851]

Thank you for the info! Could you tell more about whole electronics setup for HSB-9360TH? I'm trying to build raspberry-controlled ornithopter but not sure how to connect it all together.

[@oracid]

In the video, is the flight of the birds at real speed? Why 2 servos for movement, when one would be enough? Anyway, very good work !

[@d4ro]

By two servos it allows full directional control

[@oracid]

Do you mean turning left and right ?

I purchased a ornithopter from ornihobby. Despite a few weak parts, it flies quite good. I wondered about converting the main motor drive to the central spur gear to be belt driven with a lower kv motor.. But after seeing this, I'm wondering of servo drive on each wing would be better.

It's really impressive .... Could you please tell me where I can buy the servo controller ready to us ?? I understand that the board you mentioned in the video is just the hardware ?? but it needs the firmware to run it ... Thanks a lot

[@bonafide9085]

I just keep coming back and realizing how good your build is. I have built my servo driven ornithopter, but the some aluminum gears in the servos are failing. I need to address this issue but I'm looking for alternative designs as well and I found your channel. Did you make the aluminum servo horns?

[@bobkreutzer869]

What were your reasons for using the adafruit controller over the Arduino?

[@bonafide9085]

What is the reinforced wing material that you use? Could you please link where I can buy that?

[@OrnithopterZone1]

Like many ornithopters a high performance kite fabric is used. This one is a polyurethane coated polyester called Icarex. It is difficult to source but I have been able to find it on ebay.

[@bonafide9085]

@@OrnithopterZone1 Thank you!

[@bonafide9085]

@@OrnithopterZone1 I have purchased kite fabric, it is really strong. I see that the material is sewn, but you also use some kind of glue to hold the thin carbon rods in place. What kind of glue or glue tape do you use for this? Thanks!

[@Pluzzie]

that's really really COOL! wish more hobbyist do more omnicracft rc

[@ShittuOlanrewaju-d9s]

Please what the toque of the servo And any links to get that servo?

[@OrnithopterZone1]

Speed and torque for each of the three servos tested are shown in the video. The best servo for this ornithopter (of the three that were tested) was Hitec HSB-9360TH. It has a torque of 17 kg-cm and speed of 0.06 sec@60deg at 7.4 volts. As mentioned in the video, using a slower servo with more torque, HSB-9370TH, was not helpful. Additional information on the servos can be obtained from Hitec: hitecrcd.com/products/servos/digital ...or Servo City, which is also a good place to buy them from: www.servocity.com/servos

👍 . I would love to see a more realistic wing stroke though. Folding in during the upstroke and pushing the wing forward during the downstroke. Seems fairly inefficient with the straight up and down. But I understand the complexity goes up a fair deal.

[@RedZone54]

Would this fly using Spektrum equipment (receiver and transmitter). I think I saw a 1000mah battery in the specs - on average, how much air time does this give you?

[@playframe6231]

Make the wings bend!

[@kaspulanwar7082]

could you tell me about the centre of gravity position? is it 1/4 chord from leading edge?

[@meregaming1770]

Would it be possible to use hydraulics?

[@frost-hex]

Amazing! Thanks for sharing

[@Rahsajati]

Very good job. Very realistis...👍🎉😊

[@michaelrtreat]

So cool

[@nivimg]

Cool, now put a HD FPV system on it and send it though the newest gap 😜

Can it dynamic soar😂😮
