Aircraft-unwanted roll
So I've been working on a small fighter aircraft and a strange phenomenon has begun to occur: the plane will roll rightwards all by itself with no input. I've gone through and checked, there are no weird angles or unzeroed values that should be causing this. The roll becomes more pronounced when you pitch up, and pitching down causes the roll to reverse. This has actually happened to several of my aircraft but it is most pronounced on this one because of it's size. Any insight into this and a way to counter it would be great. It's got me completely stumped.

Re: Aircraft-unwanted roll
Can you give the code for the airplane?

Re: Aircraft-unwanted roll
Sure thang...
- Code:
// [RCD]
Val
{
AIL(default=0, min=-10, max=10, step=5)
AIRBRAKE(default=0, max=45, step=10)
B(default=0, max=50, step=50)
ELEV(default=0, min=-5, max=5, step=2.5)
GEARM(default=-90, min=-180, max=-90)
GUN(default=0, max=60000, step=60000)
JET(default=0, max=100000)
RUDD(default=0, min=-15, max=15, step=5)
}
Key

Re: Aircraft-unwanted roll
It is a bug which causes a slight vibration.If you add several frames to your model,the problem may be solved.

Re: Aircraft-unwanted roll
Where would I add said frames? I really don't want to throw off the balance...

Re: Aircraft-unwanted roll
I still haven't understood a low of the bug,so I cannot tell you where you should add frames.
The rational way to solve the vibration is you make a script to control your plane.
