How to deal with auto yaw while flying?

423k realSavageMan  5.9 years ago

Edit: Problem solved. Now this post is a teaser!

The aircraft I'm making, the Cessna Citation X, has a glitch problem that I can't solve. Help needed!

If anybody can help I'd appreciate it a lot. And I will tag you on it.

    Don't you think the tail is too big.

    Try not to look at other people as they yawn

    Kinda fat. More like an Embraer Legacy Shuttle.

    I hope my new Citation project turns out like that!

    @Chancey21 Problem already solved. I may let you do some flight tests though.

    Nudge small vertical stabilizers into the tail, they don’t even have to have yaw control

    @QingyuZhou That's the genius of it. Assuming the yaw is caused by aerodynamic imbalance, the fin works on the same priciple as whatever is causing the problem. In other words, the solution scales with speed at the same rate as the problem, assuming you keep the fin close to the vertical center of the plane and you select the correct angle.

    Anyways thanks for help. The glitch is already negligible now, though I don't exactly know how it was solved

    @F104Deathtrap I think your solution might lead to more problems. What if stays stable at low speed but start glitching at high speed.

    @CoolPeach It's always better to get the problem at its root, but if the root can't be found, this solution should prevent hairloss or aneurisms.

    Huh, I guess you could try F104’s solution below, kinda crude but it’ll fix the problem. You could always try to shift k the wing pieces to fix up any dodgy connection points

    I get this problem from time to time. The easiest way to fix it is to ignore the cause completely. I just make a small vertical fin and hide it inside the vertical tail, then I rotate it by very small amounts until it cancels out the yaw problem. It creates a little extra drag, but nothing bad.

    You don't need to make the fin very big, only like 1×1 block depending on the size of the plane and the size of the problem. As for rotation, it's usually very fine: 0.72° 1.45° etc.

    @CoolPeach I've never used any scaled cockpits on any of my aircraft builds.

    Has the cockpit been scaled down? I noticed that on my recent build, it caused drag issues which lead to auto Yaw/roll, maybe try scaling it back to 1,1,1 to see if it fixes the problem?
