BEAR FM PROBLEM

Trying to correct this

 

 

nose gear will not stay on the groung and Aircraft bounces too much see below for data

Would say damping factor of the front gear, I forgot if it was 0.6 or 6.0 Have to look at home for the right entry

[rovert97 1]

it looks like it has the F-15 runway bounce syndrome

 

look up the fix for that and you may find your answer

played with that already,,no difference

[Silverbolt 104]

well, i'm not sure but it may be an Over throttle problem...

 

EDIT:

Erm, OMG how dumb i am.

well, i'm not sure but it may be an Overtrust problem...

Yea, that overtrust thing usually leaves you sitting on your bottom............................Sorry, just couldn't resist.

[Fubar512 1,350]

Move your CG forward.

[+76.IAP-Blackbird 3,557]

CG interesting, never thought about it, have to check some other planes, thanks fubar.

[Silverbolt 104]

Damn

you got me

[+Veltro2k 6,351]

Move your CG forward.

 

 

cg position ,,,hmmm ok will try

[sparkomatic 7]

also check this:

 

Nose:

RollingRadius=0.1

 

[LeftGear]

RollingRadius=1.0

 

"rolling radius" essentially tells it how big the tires are...you have a factor of ten off from the nose and main gear...might want to check that...

[+Veltro2k 6,351]

thank you all for your help..it took a small modification of cg, and rolling radius to fix it

[+76.IAP-Blackbird 3,557]

All forgot to say thank you veltro for your damn nice Tu95!!!! I like it alot!

[marcus49 0]

nice planne love to fly it some day

[WombRaider 1]

Move your CG forward.

 

with the 3 number system, how would you move that forward??

 

 

CGPosition=0.0,0.0,0.0

 

I have added to the middle number, but I would really like to know what the 3 coordinates do.

[+76.IAP-Blackbird 3,557]

X Y and Z

[WombRaider 1]

Okay, I figured that much from all the other toying.

 

So let me get this straight....

 

CGPosition=0.0, <-- Would be left or right 0.0 <--Would be leaned forward or back what would the final number mean?

[+russouk2004 6,958]

5.0,5.0,5.0

means.........in 3d world of 3ds max.......

0.0,0.0,0.0 being the centre of the model

so, first 5.0 is 5 metres to left or right is -5.0

2nd 5.0 is 5 metres forwards of centre...

and 3rd is 5 metres up

the minus before the 1st number... eg: -5.0 ..... means to left of centre and 5.0 means to right...

Just put a point and move it to the center of the fuselage

[Fubar512 1,350]

5.0,5.0,5.0

means.........in 3d world of 3ds max.......

0.0,0.0,0.0 being the centre of the model

so, first 5.0 is 5 metres to left...

2nd 5.0 is 5 metres to back...

and 3rd is 5 metres up

 

In the world of TW data.ini files, the first "5.0" value (as you wrote it) would translate to five meters offset to the right, the second would be five meters offset forward, though you got the last one right; a positive figure there would mean 5 meters above the centerline -5.0,-5.0,5.0 is what you meant, Russ

When will this Bear be available?

[sparkomatic 7]

When will this Bear be available?

 

 

tomorrow...or next Tuesday...could go either way...

[colmack 662]

tomorrow...or next Tuesday...could go either way...

 

 

nope nope......I have heard atleast two Weeks

[+aleks 9]

veltro, fubar 512 is right.move forward in y-axis about 2 meters the cg position throughout ini file.also, increase the diameter of the wheels, in order to staysome more out from the corridor.nice work

Ok guys problem was resolved. in about a week I will be starting with the release of an older Bear Model and finish with the release with

the Bear H and if time permits the Awacs version of the Bear. Again i will create it with a temp Skin, but if anyone wants a first crack at it please IM me. some pics will soon follow.
