Planes shake violently and veer to the right

[daniel]

Yeah.. The title pretty much describes my problem I'm quite a "pro" at ksp, and I've made hundreds of planes before, and whenever my planes take off, they begin to violently shake, and veer to the right. I checked the symmetry multiple times, and its fine. I'm not even using any mods, except for the clouds and city lights mod right now. This isn't a single plane, but every single one. Does anyone else have this? I could fly my planes perfectly fine before .23, but now none of them work. Does anyone know a possible reason why? I could post screenshots of the planes, but they're fine, and it's all of my planes.

Landing gear "Toed" in or out.
Front gear having too much/little weight on it.
Check YOUTUBE they have lots of tutorials on making aircraft.

That's not the problem. I said everything is symmetrical, and I don't need any tutorials on planes, as I'm already pretty adept at making them. I had planes that worked perfectly, and I just began using them recently after I finished fooling around with the new parts, and they just began to shake violently. Anyways, it seems to be linked to the SAS. Once I turn the SAS off, it seems to fly perfectly fine.

"Planes shake violently and veer to the right"
They probably shake due to SAS. They veer to the right probably because of your landing gear. Mind posting a screenshot?

It's not the landing gear. I'll post a screen of my latest plane, but again, it's all planes.

Screenshots-
(They will be here soon)

check your center of mass and your center of lift. the colser they are together the less chance of your plane violently shaking. also for the veering right problem, yet agian keep your center of mass and center of weight at the same spot.

Look, obviously you're having problems with your craft design that seems universal to all of your spaceplane loadouts. It's not the changes in the game, it's your design, I strongly suggest you relook at some tutorials and see if there isn't something you can't tweak or that you've simply forgot. I was having a landing gear issue before as well due to the fact that I would have the wheels touching the ground at slight angles, but after I changed the configuration everything worked fine.

I would also suggest looking at the changes that occured after the last update to get a better idea of any potential changes in the way that lift/aerodynamics that might be having an effect on your previous designs.

Seriously, everyone is giving you good suggestions, stop flippantly ignoring their advice because you're a "pro" ksp player and think you've mastered a game (still in development) about orbital mechanics. Sometimes its necessary to consult outside sources to better improve ability.

I got screenshots of one of my planes. I only took them of one, because again, its happening to all of my planes. I know it's the SAS, but it was happening on the runway too, and even when it was disabled. Once I disable Reaction wheels, it works fine. I also notice that it happens to pods with SAS attached in orbit. Another thing I noticed is when you right click SAS it says "Not enough power" and other things, even when it does have access to power. It made the pod shake randomly. Anyways, it seems disabling torque fixes my problem, and it works Incredibly. Anyways, here are the screenshots.

I think people didn't read that you have quite some experience in KSP and you don't need a tutorial on how to make a good plane.
Looks like it's a problem with your game.

Try the following:
1. Take out your Mods and see if it still happens.
2. Let steam verify your game files (right click > properties > local files tab > verify integrity of game cache), try again
3. If that doesn't help back up your save folder, delete the game files and download it again. Also download the newest version of your mods.

Landing gear is not fine
You need to make sure they aren't angled like that.

Thank you, someone who actually read my post and offered usefull advice.

Yes, it is. It's easier to take off if the landing gear is angled because the front of the plane is angled up. This way it takes less thrust to take off.

Post rewritten - turns out what I originally said didn't matter.

I made a replica of the plane. Turns out it wasn't actually what people were expecting. The craft takes off fine (heck, it takes off faster than a Yak-54). The problem is when it's in the air - the vehicle shakes like crazy while SAS is active. Disabling SAS results in instability.

I'll fool around with the replica and see if I can fix the problem.

You know, instead of arguing with people, just give a different landing gear configuration a try, like mounting the gear on the wings rather than the fusilage.

I'm not trying to argue; I'm just pointing out that landing gear configuration doesn't really matter.. all it's used for is landing and taking off. Also, I know I'm being a bit touchy here, (sorry) but I've made crazier plane designs before, and It's basically the first thing I learned to do in KSP (make working planes), so it ticked me off when people told me to check a tutorial. Anyways, it turns out that a few files corrupted. It works fine now.

Strange. I remade your aircraft on my instalation and it acts just like you described, yet my own aircraft handle fine. I re-wrote my previous post as soon as I noticed this.

I'm glad I could help you :)

If you ever run into this problem again, try messing around with the wing angle. Straightening out the delta wings fixed the shaking and stability issues.
