Spyder prototype #2, flight 2

[Theanonraider]

Wow that's quite impressive. Did you have to program anything ?  Did you guys make the parts out of scratch of bought a kit of some sort and did some modifications?

Great project.

[JasonDorie]

@Theanonraider - The whole thing is from scratch (aside from the motors and motor controllers, and the remote receiver). I programmed the control board to listen to the remote and the gyro, figure out how the orientation differs from what the user wants, and sends the correction controls to the motors. I have video of the newest version posted (see the "First Crash" video, and it's significantly more stable.

How much autonomyat a given weight?

THX.

[billmalta1]

background looks like are 51 lol

Nice build

[taliewacker2007]

no make a man size one lol

[awais142]

great now all u need is some glowing lights on its edges and fly that thing in the night sky. next morning your invention will go famous on the news. UFO hahaa

[bogomir67]

That's interesting! Aren't they the Hacker A20 ? What size are these props then? 8"?

And they are still lighter than anEPP1045?

I use EPP0845 with small motors (20/5), and the 10" variant on anything bigger, up to about 200g hover load per prop. The 12" are too soft, so around 12", the APC SF 12x6, or 12x3.8" are used. But it takes a 36mm dia motor (or bigger), due to the weight.

[bogomir67]

Try EPP1045 props instead of thoes 3-bladed ones. You'll get more efficieny out of it.

[JasonDorie]

@bogomir67 - Those props were chosen because a) these motors spin too fast to use the 10" props, and b) these props are significantly lighter than the 1045's, so they accelerate and decelerate faster, allowing for more control. Two-bladed props also don't look quite as cool. :)

COOOOOOL

[Cryto]

What type of Motors did you use??

Brushless? PLain DC? What Voltaje?

Great Job!

[mdivinc]

5 stars, are you using Ti (thermal intelligence) to keep it so stable?  Very nice machine!

[rodstartube]

@mdivinc thermal inteligence? lol, WTF, you refer to FMA's horizon's sensors?, those just suck, and in this case I think they must be using an IMU

[JasonDorie]

@rodstartube - No, he probably means thermopiles, which many quads use to detect the horizon line. They work by using the temperature difference between the sky and ground. They're not reliable in situations where there isn't a good line to the horizon - nearby trees, buildings, etc.

[gordonputfile]

What sort of sensors are you using for attitude control? Great video, thanks for sharing.

[k313k]

I doubt he's using any form of altimeter. It's RC, so controlling up and down is as simple as putting more power to the props or applying less. Same idea as a helicopter.

[gordonputfile]

Thanks for the reply. I was referring to "attitude" as in horizon control/gyros etc. I just got the 6 degrees of freedom board with the additional vertical board / gyros.

[waruma]

Very cool project dude! Where did you get your motors and 3 wing propellers from? Also, how did you attach the motors to the propellers? This is an awesome project!  Nice work.

[oceanmasterza]

military is using something similar that holds a high powered "rifle" to be used to shoot "things"

[EuReKaDeAdScOpE]

Lol to "shoot things"

[GWJax]

Great Job!!!! I love the fact you used a Parallax Propeller for the MCU..

[mike478911]

Great project I hope some day you'll share your code.......nice!.....nice!

[omgitsaliv55]

This is an AWESOME project. Where did you get the motors and propellers from?

[diderot321]

Great Job...but a question....

What happens if an engine fails??

Would still be possible toland it???

[JasonDorie]

If an engine failed it wouldn't balance properly any more, and would fall out of the sky. Luckily electric motors don't fail often.

[DarkonekoHellsing]

if there's an emergency-shut off of the opposite-side engine, wouldn't it be able to land not too badly ?

[CrispinProctor69]

Very cool! Looks very stable and subdued. Software working well then.

On the failure side, you could get it to shut down the opposite motor. Then, any tilt around the "working" axis could be negated by the working motor. Reversing the motor would push it down, "normal" would pick it up. It would be tough to do and avoid any oscillations which would cause it to run away. At the same time you could slow down the working pair for a softer crash landing. Just an idea :)

Still - awesome as it is.

[mickvk]

Nice job. The gyro stabilization is key. I've seen other attempts with out a stabilizer - can't even hover for more than 3 seconds.

[overfrozen1]

dude this is awesome!

you got to tell me how to make this, post some sort of instructions for it

so much potential

[overfrozen1]

how fast can it go?
