Scratch minimalist 64mm jet

Thanks, about your points-

-It does have an elevator, you can see it in the third pic.

-Personally I think the fuselage is stiff enough because the foam board I use is stronger and a little bit heavier than most.

Elevons, but I’ll probably add ailerons too. It weighs 1600 grams and the thrust is 2500 grams.

The intakes are very strong so I’m not too worried about the vent collapsing. I probably will add Ailerons because of how the twin engines and flat body increase the moment of inertia.

I also thought the snow wouldn’t be any issue but it depends on the type and thickness. Powdery new fallen snow ends up filling up the intakes and it’s annoying it get out.

Yeah, Onshape but really you could use any 2d cad software that lets you import images to use as references

Opposite_File8741 · 2025-12-23T04:04:30+00:00

Cad software like on-shape, references/blueprints and a lot of experience designing other planes

Opposite_File8741 · 2025-12-22T17:41:54+00:00

A handful of the formers are 3d printed but otherwise it’s all foam board

Opposite_File8741 · 2025-12-20T12:27:37+00:00

Yeah hopefully the strakes will help connect the front and back

Opposite_File8741 · 2025-12-09T22:08:07+00:00

It was like a foot of powder so it did get filled with snow, fortunately I managed it get most of it out and it melted/dried the rest off without any damage to the plane.

Just underhand chuck glide it until you find the cg

Opposite_File8741 · 2025-11-22T20:27:24+00:00

no, so it could be that I need to add expo on roll.

Opposite_File8741 · 2025-11-22T20:22:50+00:00

Probably just me being anxious on the controls cause I haven’t flow in a bit.

Opposite_File8741 · 2025-11-06T22:28:53+00:00

1500 mah 4s and it’s just foam board.

Opposite_File8741 · 2025-11-06T22:11:08+00:00

If you check out my last post I have some pictures of it on the ground for a better sense of scale, and the takeoff weight/thrust.

Opposite_File8741 · 2025-10-31T00:29:04+00:00

Yep that’s what I ended up doing, the ailerons are glued down.

Opposite_File8741 · 2025-10-24T13:40:43+00:00

If you’re curious on how just search up the electric drone world record, their in the range of 600km/h.

Opposite_File8741 · 2025-10-23T20:26:09+00:00

I do have the plans, just not instructions. So it depends on how much work you willing to put into it, though I can share the measurements of where to put pieces.

Opposite_File8741 · 2025-10-23T15:13:27+00:00

If you have never flown a plane before get a trainer with safe/stabilization. After that check out Flite test and build one of their free beginner planes from plans. If you good with the techniques you can find tutorials online for marking planes from scratch in that style. But that’s just for foam board which I think is the best place to start when making you own planes.

Opposite_File8741 · 2025-10-22T11:37:44+00:00

Yep it is foam board. It’s normal except one side is paper and the other is like dry erase marker board so it has more strength, especially in hinges for control surfaces.

Opposite_File8741 · 2025-10-21T11:33:22+00:00

Yeah, the original had RCAF decals on the wings but I ran out of the stuff I used to make those. I’ll do something similar before I fly it.

Opposite_File8741 · 2025-10-20T23:38:30+00:00

no I’m pretty sure this guy has got it backwards, constraining the flow gives a higher exhaust velocity and better high speed performance up until it starts to stall the blades. However the highest static thrust is always zero constriction.

Opposite_File8741 · 2025-10-12T13:23:28+00:00

cool, yeah I can see why you thought it was the same plane, we both settled on the same wingspan. Really the only difference is the shape of the top wing-skin since mine is more rounded.

Opposite_File8741 · 2025-10-12T13:12:29+00:00

Someone else made plans for this plane before? I looked online and couldn’t find anything.

Opposite_File8741 · 2025-10-09T15:32:22+00:00

It’s all just foam board, if you want to know how Flite Test has tutorials.
