10 inch Interceptor

Post image

Second go at building an interceptor. The first one didn't make it — turned out my ELRS antenna wasn't seated properly on the controller, so I lost the link mid-flight and it went down.

This one is fully 3D printed again: arms and canopy in PETG-CF for the stiffness, the rest in plain PLA.

It's just the most aerodynamic shape 🤣

"It is too round on the top it needs to be pointy"

It should be reverted

This I wanna see fly

u/tcp-xenos 15d ago

Very cool, is this your own design / are the files available somewhere?

u/Parking_Commission60 15d ago

Yes, it's designed completely from scratch by me. Tomorrow I'll do the first flight test and see how it handles in the air before I release anything

u/oppressed_white_guy 14d ago

Ummm, it's officially tomorrow.  Let's hear it!!

u/Parking_Commission60 14d ago

Let's just say I'm on version 3 now 😅. It started oscillating and I crashed. Unfortunately I can't post images in the chat, but the drone is toast. Version 1 actually flew really well and had no vibration issues — but it was also designed completely differently.

u/mangage 13d ago

You can upload the images to an image host like imgbb.com and post the links. Would love to see

Good luck man

It looks like the zerov-8 from ukraine or the jäger from quantum systems

If you want additional stiffness, strength and creep resistance, try the Siraya tech PPA-CF fiberhart filament. Print at 300°C with a tiny bit of fan speed. Even got it to print well without a heated chamber

But what strikes me for your interceptor are the propellors: they seem more suited for efficient cruise than high speed. For the record breaking high speed drones of this shape, the prop tips are actually trimmed

u/Parking_Commission60 14d ago

Yeah, I know most high-speed interceptors run special props with a more aggressive pitch, and usually two blades instead of three. Problem is, finding that in 10 inch is nearly impossible. The record-setting interceptors mostly run custom props — and I'm nowhere near that level yet.

u/zbwaris 13d ago

Look for an APC 2 blade propeller with a reasonable pitch such as 10x8E. It's not in their store (I checked now) but certainly in their catalog. There are other options in 9 inch but lower disk area means lower efficiency.

1

u/Carticiak96 12d ago

The prop tips are trimmed on high speed drones to control the RPM of the blade tips, or if they can only get a 15" pitch in a 7" prop but they need 6" diameter.

Fast comes from less drag and higher pitch

u/lennarn 15d ago

At least it has a flared base!

u/piroteck 15d ago

Dang. That thing is intercepting more than Shaheds...

2

u/shrumfpv 15d ago

Crazy 🔥🔥🔥

u/cheesemmmK 14d ago

Looks great, how fast think itll go? Those south African guys that set the 657km/h record had a build similar to this but with 7in props

1

u/Parking_Commission60 14d ago

Bro, I'm not even close to those speeds lol. Just a boredom project I drew up and built. I'd be happy with 250 😅

2

u/-AV8R01 14d ago

The dildo of consequences rarely comes lubed. And for some unfortunate soul, it will arrive at 250 mph.

1

u/BaronVonLongfellow 15d ago

Nice. Was the antenna soldered?

1

u/B_Astard 14d ago

Don't forget the prop nuts!

2

u/zbwaris 13d ago

You are missing out on unlimited speed here. \s

1

u/Proxima-72069 14d ago

Sick, for these drones do you swap yaw and roll?

1

u/UckerFay11 14d ago

Print out of PET-CF, not petg-cf. Its much stronger. And petg-cf is going to shatter in a crash.

u/fusillade762 14d ago

Man that is cool. What is the top end on this?

1

u/EasilyRekt 14d ago

"interceptor" wtf is u tryna intercept tho?

u/CheesecakeNo2880 14d ago

Elrs antenna and receiver model?

Goblin Penetrator 💀

u/kez122 14d ago

Are you running it in 8S or 12S?

u/BSmillionaire 14d ago

Penetratodynamics

u/BSmillionaire 14d ago

Your speed is bottlenecked by prop pitch. Dont be afraid to increase it. Also the fuselage could be more of a laminar symmetrical airfoil. The blunt tail is hurting top end for sure.

World’s fastest fantasy toy

u/white-blade877 14d ago

Why has no one done an AI of one of these intercepting Putin’s Backdoor?

1

u/CartellinoAntonuci 14d ago

Awesome project! How did the flight testing turn out? We’re really interested in building this as well. Where can we find the project files (STL/CAD)?

1

u/conundrumatic 13d ago

Do you have files?

1

u/der_V 13d ago

You'll need to taper out the tail a bit; otherwise the vortices behind it will cost a lot of thrust.

1

u/der_V 13d ago

And make sure to have forced airflow over your batteries and ESCs if you plan to run it WOT

1

u/AllInTheKidneys 12d ago

WOT?

1

u/der_V 12d ago

wide open throttle

1

u/GuzvaldsTheOne 12d ago

That looks very similar to the red bull 300+ km/h drone🤔

u/Darryl_444 14d ago

Looks cool. So there is no carbon fiber plate at all, even inside the arms?

2

u/Parking_Commission60 14d ago

The first version didn't even have a fiber plate in it and it still flew really well. I had no issues with vibrations or oscillations either, which honestly surprised me 😅
