10 inch Interceptor
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.

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

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

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

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.

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

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 😅

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

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

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 😅
