Control surfaces, aero,..

[Nookos]

Hi,

I'm trying to mod for the first time. I've been struggling with control surfaces and aero these last few nights so I thought I might ask for help. A few questions:

- I tried to make a tail with rudder for an airliner ( A300) And couldn't get it to work with node stack. The rudder would pitch but not yaw. So the only way I found is to export it as an horizontal stabilizer and use attach surface instead. So it is solved but I m still wondering if there is a trick to make it work in node stack?

- I have spoilers on my wings and I would like to have them be used only to brake and tiny roll adjustment. But they can only go up so I use the moduleaerosurface I took from the stock airbrakes ( module control surface would make it go down through the wing right?) But then with that module I can't seem to activate it for roll. Only pitch and yaw are available. Any way to force that module to use roll? Any way to make modulecontrolsurface only go one way? ( green in the pic)

- Then there is the flaps problem. Right now it's just an animation and I use actiongroup to position them. But it doesn't work at all. The plane vibrates like crazy and accelerate super fast. When the animation is playing all is fine. And sometimes, below certain speed it stops the crazy vibration and acceleration with flaps in fixed position. So not much success there yet. Any tips on the method to include a good flaps system? Any idea why the vibration and acceleration? Any example of well functionning flaps in a mod? I couldn't find one. Only flaps used as control surfaces. And I would like to keep the translation before the rotation so I don't like that solution.

- Any links to a good thread/tutorial on aero and so on in ksp is welcome. I haven't found much information yet, almost nothing about it in the compilation thread ( sticky). All tips, advices and good examples are welcome to. The early wip craft here in case my questions are not clear enough and to provide more tips for the willing ones.

part of the reason there is so little documentation is because aero just got overhauled, and some of the modules you're using (like moduleaerosurface) are brand new, so the community hasnt really had time to experiment with them yet.

Thanks gkorgood.

Well. It's getting weirder and more confusing every day. After 3 evenings spent fiddling with my wings I finally found out the engines are probably the problem regarding the vibration and crazy acceleration resulting from the vibration. Not sure yet what is wrong with those engines though. At first it seemed like my intake air parameter were overflowing and causing the problem. But further test didn't prove that to be entirely true. The problem is greatly reduced but still appears. Especially on descent at low altitude. Seems like a drag issue of some sort but I haven't found out how to get rid of it yet. It's the same wobbly disaster as timewarping a flying plane but without the timewarp :S

I think it's the engines because when I replace them with stock engines it seems like the problem is gone. Even weirder, my flaps animation has absolutely no effect when I use my engines. But when I use stock engines with srfattach the flaps produce drag!! ( no lift though) I'm puzzled. Any clues what is going on?

Still need to sort out : - Vibration/ crazy physics ( could it be node stack engines? so srfAttach stock engines are fine? I need to test my engines in srfAttach when I have time. If not that I have no more clue what is going on with those engines)

- Flaps producing drag but no lift ( is it possible to add a moduleliftingsurface to affect only one mesh in .mu file? or modulecontrolsurface with 0 ctrlsurfacerange would still produce the lift with animated parts? again plenty of tests to make when I have time if nobody knows)

- node stack rudder yaw instead of pitch

- finding a module for spoilerons using roll instead of yaw ( restricted modulecontrolsurface or less likely roll forced into moduleaerosurface)

The updated crafts (my engines and stock engines version) for any good samaritan with some understanding of aero. Thanks in advance for any tip, guideline,..
