Custom landing gear has issues...
Pokes through the top and bottom
Rips clean off
I've been building a fun jet that performs well, except for landing gear. If you pull high-G turns, the gear will poke through the fuselage (#1), or the springs will lose all structural integrity and rip right off (#2). Drag is false, weight is changed on pistons, shocks, and rotators. According to BodganX, it is an issue with nudging parts around and attachment points. So far a solution hasn't been found. I do think that rotators, shocks, and pistons need some sort of revamping/fixing, or a locking function to prevent them from moving. If anyone has any ideas on what may fix this, please put it in the comments!
Edit: I've also tried magnets with varying degrees of success. They either break the gear or don't hold it in place well enough.
It appears to be the shocks causing most of the trouble, as nothing moves after the wheels and shocks are ripped off.
The plane also veers off on the runway, probably due to poor landing gear.
Here's a link to the plane if you want to hands-on try and fix it.
Edit #2: I've fixed the shaking/falling off problems (omitted the springs and pistons, re-did the gear doors), but now it veers off to the right or left, depending on which side was last mirrored. It is a landing gear issue because when I remove the custom stuff and put in default gear, the issue goes away.
Thank you everyone for your help!
Bro my landing gear is always wobbly and how do I fix it
This is what happens when you try to Supercruise the J-20...
@exosuit Yes
@BagelPlane did you see my comment
@exosuit Yeah I know, I was just showing what happens in high-G. Sometimes the gear comes off when retracted too.
You aren't supposed to lower your landing gear at 650mph
.
If the landing gear well is hollow then enable part collision on the wheel and the gear door. If the landing gear well is solid then disable collision on the wheel well and enable collision on the wheel and the gear door.
I've found it's best to just have shocks for show. When it comes to realistic aircraft weights, especially modern aircraft, they're just too much trouble. Even if you can get them to work after many hours of frustrated tinkering, the landing gear tends to be so springy that the plane bounces down the runway like a pogo stick.
For shocks, I simply increased the strength to 1000% and damper to 500%. I've also changed mass scale from 15 to 1. The ripping no longer occurs during high G turns with gears down.
.
For the nudging, you have to take the nudge into account when you design your landing gears. Unfortunately, that's how it is until we get perfect rotators, pistons, and shocks.
.
To alleviate the veering, I set forward and sideways traction on the nose wheels to 50. There is still some veering, but not as exaggerated as before. I believe there is some underlying issues with wheel physics. I've send a bug report about it for 1.10 beta but it seems that the issue may not be resolved anytime soon.
.
This little exercise makes me wish there's a proper parts manager. It was tiresome trying to select a part that is hidden in another part.
@BogdanX Thanks!
@BagelPlane I dont know but after i added one more connection to the each of the tire the problem is gone, Maybe that the way to fix it?
@CenturyAerospace Thanks! I’ll have to try it later.
@Dad Will do
@marcox43 Thanks!
Try making the springs a lot longer
@BagelPlane I'll tag you on some of my Subassemblies, maybe they can be useful to you, feel free to modify as you please.
I was able to fix the nose gear but I am not sure about the main gear, never directly connect pistons and springs as it can cause a very weak joint in between them, here is the version with the fixed nose gear
rip in pieces
@BeryllCorp Magnets don't work all too well, I've tried them. The shocks have default collision response (Default) and are set to
DisableCollisons=True@BagelPlane springs usually bug out when collision response is set to None or DisconnectOnly
.
Try locking it with magnets...
@rexzion Give or take, it is all around
massscale=1. The rotators, shocks, and pistons have more weight to "increase" structural integrity,@Ryn176 That actually causes it to bend out more.
Try adding mass to the part that the wheels are connected to
@BagelPlane is everything that is the landing gear have
massScale=1@rexzion Already tried that, it seems to be a bug with rotors and shocks
