Why are the Fat-455 wings so garbage?

[AoD_lexandro]

So Ive been trying out the Fat-455 wings for some spaceplanes and frankly they are atrocious. The slightest G-forces rips them right off the plane, attaching wheels to them makes them fall off on the runway and only by using redonkulous levels of strutting have I been able to make them stay on in either case. Every other wing section, part, etc is no where near as "weak" structurally. They really are the worst aeroplane wings I have used in the game.

Yes I have used autostrut properly and I know how to make wings work. I have several wing shapes I have made with the boards that do not have the same problems. Hell I have a Mk3 that does 1200ms in the atmosphere and can easily pull high G without snapping.

Methinks someone at SQUAD needs to fix these things so they can actually flex & handle G-forces properly.

Has anyone else actually made them work for spaceplanes that arent the weight of a flea?

You've got me wondering, with mingled awe and horror, what kind of insane things you must be doing at KSC, because I use the FAT-455 regularly (it looks BADASS with the insignia of the Galactic Empire on it!) and I don't have these kind of shenanigans. The part works fine as a plane wing, though the lift-to-mass ratio isn't the greatest.

[AoD_lexandro]

Im not doing anything special at all.

Litterally just added them to the fuselage with a set of engines on pylons via autostrut and they fall off when I pitch at mach.

On the runway if my plane is heavy they fall off if the wheels are mounted on them.

I had to go strut nuts to get them to stay on but it causes slowdowns due to excessive parts. Everything else is dandy, no other wings show any kind of problems unless Ive forgot to autostrut. Just these Fat things are a problem.

Then I'll take a wild hunch and say you might have a corrupt part file.

Have you tried all three autostrut modes? (root, grandparent, heaviest)

I have no problem with the fat455 wings

Yep tried them all thats why I went to manual strutting. I had to make an A frame across the wing root to keep them on.

As for a corrupt file, steam verify didnt turn up anything. And I dont think its a mod issue as they have been bad since I got them in a vanilla save. Im just posting now because I was trying to use them for a proper Mk3 SSTO but ........shenanigans.

I honestly dont know. But for me they are terrible.

[GeneralVeers]

There's only one other thing I can think of (and this is yet another wild guess):

You said the amount of struts needed to keep this plane's FAT-455 wings on is causing slowdowns? That doesn't sound normal. It has me wondering if your computer can't handle the workload and is fumbling some of the stuff it needs to be doing. Missing part updates or physics updates or something. If your computer drops a part update and a part ends up in the wrong position, the computer may think it came unglued from the plane.

As I said--wild guess.

You could try taking your gave save and playing it on somebody else's computer (preferably a beefy one where you could launch a friggin' Star Destroyer and get 60 FPS) to see if you get the same result.

On the side, could you post a screenshot of this engine of devastation you're trying to fly?

[AoD_lexandro]

Im pretty sure my rig can handle it. Its an i7 4770k with 8gb of Ram and a 270x GPU on Win10.

When I say excessive parts, I mean like 150+. 100 for the ship 50+ for cargo.

The game starts to chug after 100+ parts are in flight, and my Mk3 system is for launching large cargo, so the original one I have is 80+ parts dry. The Fat version is 100+ because I added a full A frame system to hold the wings on with about 30 struts in total. I went overboard because I was getting peeved.

By the time I load cargo the FPS will tank in flight from excessive parts. Its actually from the aero effects, because as soon as I leave the atmosphere its fine again. I think the aero effects are trying to render for the internal cargo parts as well as the ships external parts. But thats a seperate issue entirely outwith the wings themselves.

As I said everything else is fine, and the slowdowns are to be expected with the number of parts Im flying to space. Just these silly wings keep falling off.

Minor facepalm incoming. :)

I use the FAT-455 TAIL FIN regularly. It works very nicely as a wing. :) Only just now, while looking through the stock parts list, did I notice there's also a FAT-455 WING.

However, looking at the FAT-455 wing part cleared everything up. Here's the problem. That wing is big and long (bow chicka bow bow). It also has the highest amount of lift in the game, unless there's some OTHER part that I missed, which as we just saw is occasionally the case. A large force, being applied far away from the mounting point, means much more stress on the mounting point. Cue sound of sheet metal being ripped like paper.

So, yeah. Hate to break it to ya, but it's plain old basic physics here. :(

You might be able to save partcount by moving some of your fuel tanks to the tips of the wings. Getting gravity to pull DOWN might take some stress off the A-frame and allow you to get rid of some of the struts.

I personally think it is bugged. When loading a quicksave of a vehicle with those wings, the wings spaz out and explode the moment time starts. Can only be solved by having unbreakable parts and joints switched on in the debug menu.

[GeneralVeers]

Having had ♥♥♥♥ go seriously wrong a few times, I've long since stopped ever quicksaving in atmosphere. Bad things happen. Parts fall off, parachutes break, planes explode, economies collapse, nations die, worlds crumble into hopeless dust, dreams are crushed into despair and oblivion. To quicksave in atmosphere is to invite the Angels of Damnation into your soul.

And all those things happened when I quicksaved ships that did NOT use the FAT-455...... :0

Never had any problems with these wings, I've used them on quite a few large designs.

They can be pretty heavy if you have them filled all the way with fuel, have you tried shifting some of your fuel payload to the main body instead of the wings?

[AoD_lexandro]

Yeah I always have them full of fuel, thats the only reason I would use them. Wing boards dont have tanks so for some ships I use the Big-S delta & strake with full tanks and thats pretty good. I was trying to get the FAT wings to do the same thing but...shenangans as mentioned.

The wings to me feel like they dont flex properly, which is a no no in wing design. Large aircraft wings should flex quite considerably in flight. Im a FSX sim pilot on occasion so I know my way around a large aircraft and its dynamics. I actually fly a 747 or a dreamliner most times in FSX. These kinds of commecial craft have wings that flex up to the height of the cabin or more in some designs. The FAT wings "feel" like they are just bolted on with zero flex, so when Im pulling G they dont flex and just transfer the load to the mounting point and snap.

I really dont get it. Is it a bug? Is it just my install? Could someone post the part file or a summary of it so I can do a manual check?

[GeneralVeers]

That's part of why some of us asked for a screenshot. Can't test it unless we see what conditions produce the disassembly. :)
