BTW what program do you use to make your 3D planes? This seem harder than it should be...But that could be because I am not that great at 3D yet! š

That's still pretty heavy. The nose cone on my comparatively sized Saab 105 is only about 11 g and even on my big 6 ft long 90mm EDF is only 24 g

Fusion 360 since it's free but still runs local on my computer - but I've seen people use Onshape too pretty successfully, and I think pretty much any full featured CAD should work well.

It's one of those things that comes with practice. There are typically a ton of features built into CAD that differ slightly between programs, so the basics are easy, but to go fast it's a matter of learning what tricks work best for you. It's also worth using a mouse, if you have one, since using CAD with a touch pad is a huge pain

Yup, I work on a desk top š

Ah okay, I use linux so Fusion 360 is really hard to setup...(Also my PC is slow, so having in web based in nice)

Still seems lighter than a MS plane would be....I should weigh my p-38 lightening nose cone...

Actually yeah....As I do content writing I have tried both ChatGPT and Gemini and I find ChatGPT is more "intelligent"...

Yup, agreed. Though I hardly use either.

Yeah, I only used it for technical outside of work usually..

I think this will be about the class of the FMS 64mm version:

Looks good
Sorry Iām a little late to the replies ā¦ I am obviously partial to foamboard as a construction material, mainly for its flexibility, durability and ease of use. That said, it is likely that a 3D printed airframe will āgo fasterā simply because you can make the whole thing much āslipperierā, however it will be more fragile.
The biggest thing that will get you speed at this size is the right power system: you need a high performance 6S EDF, and a small high-discharge battery to keep weight down.
Personally I think you could do 100mph with a foamboard airframe - I think Iāve been close to that speed with mine, but Iāve never measured. Maybe you could build a foamboard one first as a powerplant-testbed while you design your 3D printed one?

Yup, it could definitely be done with foam board, the fastest I've gone with foam board was 155mph. And I know Joshua's Sharknado went faster (with triple the power) But I'd love to see a foam board EDF hit 150! (then I'd have an excuse to buy an EDF š)

The main reason I am intrigued with a 3D printed plane is that I might actually be able to have a super scale plane like those ones I have always anted to buy bu been never able to justify....

But making a foam board design isn't a bad idea, then everyone else could still make it!

I second pretty much everything Mid7Night said about 3D printing. From experience, 3D printed planes can be noticeably faster than foam board planes on the same power system. You can just get thinner sections stronger and more reliably with a PLA than with foam. I think this is even true for injection molded foam due to the strength limitations and you really need balsa or composites to compete with 3D printing purely from a low drag perspective.
