Uncontrollable

37.5k WiiMininininini  4.0 years ago

I am making a DC-3, but the plane flys pretty normal once you take off, then when you just desend, it does a front flip and starts crashing, but when normally climbing, it doesn't. How do i fix this?

    @PhantomAviator well I wouldnt be trusting roblox for your advanced aircraft physics. SP either. But like @DerpTheSoyacfartala said, fighters attempt to bring the CoM and CoL together in order to make the aircraft unstable. And like @AsteroidAsteroidTheBook said, "they have better controls" which is pretty much true.
    .
    Fighter jets have really smart computers on board, which keep the plane's forces perfectly in balance until the forces need to be unbalanced, which takes place very quickly--which is very important in combat.
    .
    But for this DC-3, other airliners, and pretty much all GA aircraft, you want to be mostly stable so that the planes are easy to fly. But there is a problem of overstability which causes undermanevuerabilty and if you can read that whole word(I barely can lol) it means that the plane basically cant change direction very fast.(a big portion why airliners are low-wing)
    .

    Post an unlisted build with a link and tag someone else to take a look at it. I’d probably be able to tell you what’s happening in about 3 mins if I could test fly it.

    @XP Lol yeah, i turned an F1 car into a plane, so I probably shouldn't have expected realism

    @DerpTheSoyacfartala so if you want to know, its that I remain silent as I get into the zone while building, so I fixed the issues, because of @UltraLight telling me to remove jet engines and xml mod the propellers, which fixed it. Then I used structual wings, and added some more text to the aircraft in Amharic, which is crazy hard, then I finished. Then I opened simple planes and continued fixing my DC-3

    @UltraLight Close CoL and CoM do this? I played a roblox plane building game and was told to try and get those as close together as possible. I guess the best practice is to just guess where the center of your plane is and try and get the CoM there?

    @AsteroidAsteroidTheBook true
    fun fact
    the McDonnell douglas DC-3 actually revolutionized the primary wing shape for flying
    before then the wing shape didn't produce as much lift
    it wasn't until the DC-3 they started using a similar wing shape for other aircraft

    @AsteroidAsteroidTheBook fighter jets literally do that XD
    the center of mass, lift and thrust are so close together
    @WiiMini
    i never had that issue
    sometimes i had issues where the plane would turn to the right or left, usually happened when i made prop aircraft... i think its because i have the wrong direction set

    you must remove mass of wing fuselage using overload mod

    @WiiMini ok well for adding power to prop, set the maxRpm(you need to add this) to like a million or something. Then increse/decrease power as needed
