FIX for the constant roll bug on symmetrical designs

14.9k NumNumz  8.6 years ago

Is there a fix, are the devs ever going to fix it? Its messing up so many of my planes. It seems not a problem on planes with flat wings, but as soon as you angle it with dihedral, or rotate it at a non 90 degree interval angle, it makes the plane roll constantly. For example, the F-16 sneek peek i recently uploaded link , has this bug if you change the diheral on the back fins, or if I just rotate them, and the plane constanly rolls to the left. Its so annoying, because the plane is perfectly symmetrical. (and its not a drag issue, I've already checked)

    7 months after this is brought up and this crap still happens

    @NumNumz Yeah, it does need to be looked at.

    @Brields95 although actually this bug does affect some of my planes which should be perfectly stable in real life and have fins angled upwards, so this is definitely a bug.

    @JShay yeah, stuff like that makes me want to play a different game . Its just so annoying when you work so long to create somethi g beautiful, and then it doesnt work due to a silly bug, even though it should work in real life

    Definitely an issue I have with a number of my planes. I just worked on a super simple 10 part plane for the Yeti race, all flat wings, and it rolls like a fat mother... :/

    @Brields95 But yeah I see what you mean about fins angled downwards.

    @Brields95 Kerbal was super super low budget when it first came out, and it still had an SAS system

    @NumNumz Make a semi basic paper plane. With the wings angled up, as usual. Notice how when it flies, it stays mostly straight? Now bend the wings down. It should roll over. This is what your F-16 is trying to do.

    @NumNumz The F-16 has a tendancy, due to the tail dehidral, to roll from side to side, or dutch roll. Yes.

    @NumNumz Because they are tough to emulate, and SimplePlanes is lower budget.

    @Brields95 Gyros would be a really good thing, why they havent released an SAS system yet is beyond me, Kerbal had one from the start.

    @Brields95 But the question is whether or not the F-16 actually has a constant left roll in real life due to aerodynamic instability. I know its an unstable design, but that doesn't nescessarily translate into a constant left roll, Usually it just means the plane is extremely jerky or floaty in its movements, and requires a computer to properly control so that it doesnt spin out of control.

    The F-16, whithout Flyby wire, will do that. Since gyros haven't been added to the game, (or requested for that matter) we have no way of effectively stabilizing naturally unstable planes, such as the F-16.

    @AndrewGarrison rather than fix this "bug," keep it.

    Yeah, it's always been very slight but I notice it with nearly all my planes

    @WeeBabySeamus @AndrewGarrison Are their plans to fix this bug, as its been pretty prevalent for a quite a while now.

    @NumNumz Idk what the problem. I've had encounters with this in the past and its a design specific problem. Somehow I fixed them but i cant tell you exactly how i did it exactly.

    @BoxGlow Still the same problem with normal sized fins, already checked...

    try using normal sized fins and see if that works

    You should see the ultra glitchy centre of mass of my Nissan GT-R LM NISMO. Even though the whole bottom of the car is made of wing, it shows that the lift is just under the rear wing! (Weird 😱)
