The RYAN STA Build Thread

Thanks and your welcome.

Will you be putting a pilot in it? these open cockpits just don't look quite right flying without one. Just saying. Still appreciate the work even if you don't.

That's a jet fighter pilot. Won't really jive with the Ryan me thinks. I'll let you know some time later frontman. Just too early to tell how many polys I will have to play with.

On another note, the Ryan has a two piece wheel pant and gear cover. The lower wheel pant moves with the wheel. To accomplish this I had to put the ~CS_LG, and ~CS_RG components into a pivoting frame. It all works great on the ground, but as soon as it's airborn the wheel and wheel pant vibrate rapidly. If anyone could tell me if there is a way to stop this or if it's a glich I would appreciate it.

Oooh sweet you modeled the shocks too!

That sounds more like a physics problem, though I could be wrong.

I'd have to see what you've done to look for a solution.

[Boof69]

This is what I have so far. All the flight physics are in their infancy so don't expect much in that area.

[Madratter]

I just tried it out. The one thing that caught me off guard until I figured out what was going on is that you have working elevator trim tabs on Channel six. Quite cool. Until I figured that out, I couldn't figure out why it wanted to descend when upright and ascend when inverted.

[Boof69]

Like I said the physics are no where near complete. The purpose of this posting was to find the problem with the vibrating landing gear.

[flexible]

I can't speak to the gear, but on foamies I have had a fluter isue before when I got eather weight or strenght to light. I think all I did to fix it was increase the weight of the flutering part. Fixed.

[Boof69]

Sorry flex no dice that was one of the first things I tried when this problem reared it's annoying head.

Oh, it wasn't a physics problem at all. I just hadn't realized that there were working trim elevator trim tabs. That is a good thing.

Thanks MR

[opjose]

Great I'll have a look tomorrow.

[Madratter]

It is the right and left shock. You can prove this by deleting the left and right main gear children. It will still happen. If you delete the shock and all children, it does not happen.

You can also stop it by changing the rotation maximum and minimum values under the shocks to zero instead of 2.5.

Of course, that kind of does away with the point. But at least now you know specifically where the problem is.

[Boof69]

You don't understand what I'm trying to accomplish MR. I put those there on purpose to animate the wheel and wheel pants while on the ground. That works great but when it's in the air they vibrate. I could just set them up as conventional landing gear if I didn't want the shock animation. Thanks for taking time to look at it but the solution is not that simple.
