Some things that work in reality just don't in the game, or are very hard to balance right.

Especially on a flying wing that is so short back to front the pushing propellers will have a huge impact puahing the nose down if they are placed too high, and pushing the nose up if they are placed too low.

With puahing propellers it's important that they are either centered on the horizontal line of balance or that you angle them to compensate for the force with which they push down (or up) the nose. The game is very sensitive to that, that's why I jad to mobe tje propellers all the wsy down on the other plane.

One problem is its kind of lifting, but when i apply power it goes straight down

Ah I see, i've ditched the orginal design and made one from scratch

See pic here for reference

What I mean is your plane wasn't the same on both sides of the center line, the right side should be an exact mirror of the left and vice versa but your plane was not the same on both sides. Try using the mirror mode along the Y-axis in the editor to see what I mean. First example below is symmetrical - mirrored along the center line, the second is not symmetrical.

Your plane has pieces that are located differently on each side making it more unstable than necessary.

Just for clarifaction, what exactly is a symmetrical flying wing??? It's kind of a dumb question but I'm not to sure

You can definitely make it work in Legacy style building, but yeah maybe start from scratch and make sure it's properly symmetrical, that will help a lot. :)

Well, I really appreciate your help and I'm very thankful! Since I've never made a flying wing before I really had no idea what I was doing, so obviously theres a lot wrong. I like the legacy style of building and I might have to change it, but I'm probably going to do a complete redisgn or as you said, make from scratch. I also have just downloaded it so you can take it down. And again, thank you very much for helping me.

Oh please let me know when you have downloaded my version of the plane locally so I can remove it from the Workshop. :)

Hopefully this helps a bit. Good luck.

My version of the plane can take off from the ground, barely. There are issues with elevators and ailerons not being symmetrical making the plane un controllable at times, but you'll have to figure that out. Building a symmetrical plane is a good start.
If you spawn it at 600+ meters elevation in the air and let it glide until you gain control over it at about 250 kph before using the engines you can see it's somewhat reasonably balanced in flight now.
Getting a flying wing design balanced in the game is hard, especially if you only use good old Lego-that's-not-lego-for-legal-reasons bricks, but making it symmetrical is definitely a must to begin with, and only using fluid dynamics on actual wing parts in the right places.

I would recommend starting over from scratch TBH.
- Make sure the plane is symmetrical.
- Start with a few wing pieces having fluid dynamics and go from there.
- If you want the propellers to be top mounted you need to angle them or find another way to counter the force with which they push the nose down.
- Maybe start by using only oak as a material, it's light and pretty strong and is a bit easier to balance the weight distribution with a small plane.

I've tried to fix the main issues and below is a link to my edited version. I have marked all changes in different colours so you can see what I have altered.
-I removed the fluid dynamics from all pieces and added them back on flaps and the pink wing pieces
- I moved the engines and props down to balance the force somewhat.
-Minor edits to gear etc to avoid props and rudders touching the ground.

Ok I had a look and I'm sorry but it is a bit of a mess.
- The plane is very much not symmetrical at all which will be an issue even if everything else is somehow fixed.
- Almost every part has fluid dynamics. This won't work. Just adding more fluid dynamics to more pieces that aren't even part of the wings will not help, rather the opposite. Start with a few wing pieces having fluid dynamics and go from there.
- The propellers are mounted well above the center line meaning they will push the nose down a LOT whenever they are running. EIther move them down or angle them to counter the force. Sadly the game is a lot more sensitive to this than for real planes.
- Optimal angle for max force on flaps is +/-22.5 degrees. Anything above that will act more as a brake than a control surface.

Heres the N-1m not exactly finished but sorta

I found that when I made some parts of it as tugensten, it kind of flew but it flew inverted, it might be the center of mass

I can’t currently right now, but I’ll be back tomorrow which is Thursday where I have BR. I’ll send you a few pics of it, and I’ll upload it to show you. I want to make a YB-35 at some point aswelll

Since I can't see what you have built I have no clue how to help you, sorry.
If you want to upload what ypu have and share the link with me here I can take a look, but without being able to see it there's no way of knowing what the issue is, except flying wings tend to be a bit unstable and careful balancing of pieces with fluid dynamics is key.

hey uncle t, i'm trying to make a northrop n-1m, a flying wing. I used my f-86's wings, which the f-86 is from legacy. since its techinically legacy, any ideas how i can get it to fly?

I'm afraid I'll probably give the Natter a pass at the moment since I've already built the Ohka and the Komet, and the Black Widow and Ki-43 are on my list.

could you make a ki-43 hayabusa or a p61c nightfighter i havent seen either of those on the workshop

PLEASE MAKE THE NATTER IT'S THE BEST THING FOR YOU TO BUILD NEXT

Shorter version: I build whatever I want to build whenever I want to build it. Easy as that.
As I've said the I-225 is on my list, but so is over 75 other planes, some that have been on it for a year already and haven't yet been built.

oh sorry

Blue Crab that answer was directed to Master_Mamoru.

Blue Crab probably won't build the YB-35 any time soon, sorry but as I've mentioned many times before I already have over 75 planes on my to-do list and it feels a bit pointless adding more, especially ones I'm not that interested in.

Ok although i dont play war thunder it seems fun

Master_Mamoru because I felt like building this but I didn't feel like building the I-225. This buld started as a test to see if a flying wing actually works in game, and once the concept worked I wanted to finish the build because it is something quite different and unique. I've built several single seat prop fighters but never a flying wing.
I also get dozens of requests for planes and often for this or that obscure plane that people have played in War Thunder that often really wasn't a thing and really don't interest me.
So forgive me I guess for building the planes I want to build and I am interested in and not the super rare super specific prototype someone wants me to build right now bc they played it in War Thunder.

Nice a flying wing speaking of flying wings can you do a YB-35 / XB-35 hear is a vidio about it by musterd --->https://www.youtube.com/watch?v=dByvPIyIbZE'




And the wikipedea artical. ---->https://en.wikipedia.org/wiki/Northrop_YB-35

You don't want to build the I-225 because it remained in the testing stage and did not participate in the battle, but you built the Ho 229, which also remained in the testing stage and did not participate in the battle. Why? (And yes, I'm just wondering)

A few of those planes are on my to-do list that already has over 75 planes on it, but I'll check them out and see if there's some of them I want to add to my list. :)

I have some suggestions that you can build when you got time Horten H.XVIII, Aichi D3a, Henkiel he-111, Mitsubishi J2M, Nakajima J1N, Ki-43, G3M, Kyushu J7W Shinden, Gloster meteor, Bell P-59 Airacomet, Heinkel He 280, Focke-Wulf Fw 189 Uhu, Fokker G.I, Potez 630, Dewoitine D.520, Morane Saulnier-406, PZL P.11, PZL.23A. I have a lot more but you dont even have to follow these at all, these are just are just a S̶m̶a̶l̶l̶ ̶a̶m̶o̶u̶n̶t̶ of suggestions i think you should do, Thanks!
