FVD Problems

So I've been messing around with FVDs for a few weeks now, and I finally get it, but I keep having this same problem where the track will bank at about 60 - 80 degrees randomly (or become level if the track is banked) when the banking should be staying constant. Has anyone else had this happen, I can't seem to find what I'm doing wrong. Here are some pics in case what I'm saying doesn't make sense.

The first thing that comes to my mind is, is there any simple math errors?

If you want, you could post your banking and g-force transitions. I am sure the problem could be solved quickly that way.

bTimA = 0.5
bTimB = 4.5
bTimC = 4
bTimD = 2.5

gTimA = 0.01
gTimB = 0.99
gTimC = 4.5
gTimD = 3
gTimE = 3

CASE[0.0000,bTimA]{; < - - - - - - - - 'bTimA'
S=T/bTimA
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3] ;; Q
B = 0 *tFunk/57.295779
}
CASE[bTimA+0.000001,bTimB]{; < - - - - 'bTimB'
S=(T-bTimA)/(bTimB-bTimA)
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3] ;; Q
B = 0 /57.295779 - 20 *tFunk/57.295779
}
CASE[bTimB+0.000001,bTimC]{; < - - - - 'bTimC'
S=(T-bTimB)/(bTimC-bTimB)
B = -20 /57.295779 + 70 *tFunk/57.295779
}
CASE[bTimC+0.000001,bTimD]{; < - - - - 'bTimD'
S=(T-bTimC)/(bTimD-bTimC)
B = 50 /57.295779 - 25 *tFunk/57.295779




CASE[0.000,gTimA]{; < - - - - - - - - 'gTimA'
S=T/gTimA
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3]
gPunk = gfOne - gfOne*tFunk
}
CASE[gTimA+0.000001,gTimB]{; < - - - - 'gTimB'
S=(T-gTimA)/(gTimB-gTimA)
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3]
gPunk = 0.1 + 4 *tFunk
}
CASE[gTimB+0.000001,gTimC]{; < - - - - 'gTimC'
S=(T-gTimB)/(gTimC-gTimB)
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3]
gPunk = 4.1 - 5 *tFunk
}
CASE[gTimC+0.000001,gTimD]{; < - - - - 'gTimD'
S=(T-gTimC)/(gTimD-gTimC)
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3]
gPunk = -0.9 + 5 *tFunk
}
CASE[gTimD+0.000001,gTimE]{; < - - - - 'gTimE'
S=(T-gTimD)/(gTimE-gTimD)
tFunk = 6*pwr[S,5]-15*pwr[S,4]+10*pwr[S,3]
gPunk = 4.1 - 5 *tFunk


This is what you're looking at in the first picture, there should just be a smooth transition from -20 to +50 degrees over the top of that hill (that's what I'm trying to do anyway)

CASE[bTimB+0.000001,bTimC]{; < - - - - 'bTimC'
S=(T-bTimB)/(bTimC-bTimB)
B = -20 /57.295779 + 70 *tFunk/57.295779
}
CASE[bTimC+0.000001,bTimD]{; < - - - - 'bTimD'
S=(T-bTimC)/(bTimD-bTimC)
B = 50 /57.295779 - 25 *tFunk/57.295779

You have no tFunk transition formula in those two

Oh that's weird, I never noticed some of them had a tFunk and some didn't. Thanks, I was hoping it was just an easy fix like that that I hadn't noticed.

No problem, let me knowif that cures the situation.

Yup, that worked perfectly.
