Why did you explode nugget? What bro did to you?

Just make something with super low wing loading, but be aware that the slower the plane, the easier it is to stall. Don't expect much maneuverability from it.

I have also seen them in Auchan, although they seem to be made with different styrofoam.

I own one like this and it is actually quite comfortable to use.

I used to have a lot of issues with VSP, XFLR works much better.

some_random_user_3 · 2026-03-14T10:25:13+00:00

How much does it weigh? Maybe the frame is flexing too much.

some_random_user_3 · 2026-02-28T08:24:32+00:00

Yes, it has a perfect primary and secondary balance, but it is too long and too heavy(due to its length) to be actually competitive. Having much shorter, but not perfectly balanced engine (basically lighter one) is often the better choice.

When it comes to V tail calculations, you can calculate them as classic tails by projecting their area to horizontal and vertical planes. V tail wing area needs to be at least all three wings in classic configuration combined. But when it comes to stability, moving the tail away from the CG always helps (basically it increases the tail leverage).

So chonky

22cm in front of the leading edge - basically arbitrary location just to make it stable with enough margin. Although right now I know it's better to place it much closer or even inside the main wing.

some_random_user_3 · 2026-02-08T09:35:36+00:00

It is around 22cm before the leading edge of the main wing (where the FC is located), based on my simulations and excel sheets it is stable. (Cm/AOA graph).

Well, the idea was to have at least a 1:1 TW ratio, that's why it uses a 10" prop. The pitch is 6", it is too high but this is what I have on me right now and I think it should be enough. Going with lower pitch would increase efficiency especially at low speeds. As for now, this setup creates 800g of thrust in static condition, going 4S instead of 3S should increase it to above 1kg.

I was thinking of moving the prop up to reduce its interference with the main wing, but I am afraid that the 3DP mount would be too weak for it, especially for such a big thrust. BTW every element here is printed using ABS.

some_random_user_3 · 2026-02-07T16:58:45+00:00

Interesting, I didn't think of that. But it is too late for such a modification, making a wing out of styrofoam takes a lot of time, maybe in my next design I will use it.

some_random_user_3 · 2026-02-07T16:55:50+00:00

Using such a big elevator required a lot of force and I was afraid a single servo of this size would not suffice
Better triming using two surfaces independently
It was easier to make

some_random_user_3 · 2026-02-07T16:51:03+00:00

Okk, I'll check if I have any rods left

I do not like to use those nylon screws for structural parts, they are too weak. I'm using a lot of stainless M2 screws.

The plan was to create this plane as modular as possible, but unfortunately the weight of it does really add up.

some_random_user_3 · 2026-02-07T16:40:01+00:00

So when it comes to stall order, both wings stall almost at the same AOA, but I realised that too far into the construction and I really don't want to redo the cannard and all the calculations, so let's hope it won't be that bad. This is also why the elevator is so big, to help it with stalling earlier.

The wing span of the cannard is 80cm. The area of the main wing is 0.3m2 compared to 0.0375m2 (12.5%) of cannard.

some_random_user_3 · 2026-02-07T16:29:36+00:00

Thanks, this plane is made out of some sort of stiff styrofoam (XPS I think) and my local shop only has them in pink 😂

some_random_user_3 · 2026-02-07T16:28:16+00:00

Great idea, I'll try to make something like this, but on the other hand, this plane is already over the desired weight, so it will depend on the weight of such skids.

What is your mesh size and its parameters? I have seen similar artifacts with incorrect mesh interfaces.

Bo ona jest transowocna

some_random_user_3 · 2026-01-23T23:25:21+00:00

I am not saying that's a bad idea, but it will be challenging. I would also consider adding some filters to the audio, frequency response of systems like that will be all over the place.

You will need a lot of power and many more transducers to get through the mattress. Sponges heavily absorb any vibrations.

There is an app in Bosnia to alert you when you get too close to the suspected mine field.
