I am working my CFM Streak Shadow over from FSX to run in Fs9.

It flys great and handles fine on the ground in FSX.

But after compiling for FS9 i can't get off the ground in FS9

it starts to roll then starts to hop then crashes through the ground.

The contact points are right, the static and max compresion are correct

I have played with the damping but I can't get it to stop hoppping around.

Any ideas?

Thanks

Hi
Not being able to see what sort of hopping your having(mad ,bunny ,carefree Cheesy )  my first suggestion is to check the MOI values in the aircraft.cfg
check the values you have in there against a default thats close to your porject size and mass,also check the weights are in the ball park.To low a moi will cause the aircraft shake and hop but so will a heap of other things

I know you said the Static Compression values are correct, but it sounds like they are a bit to stiff.  Try lowering the value by .05 until it stops bouncing.  The damping values are used to define how quickly the strut will return to its undisrupted rigidity.  Like if you jam on the brakes while you're taxing, the nose will dip and then come back up to rest.  The damping sets how much oscillation you'll have before everything settles down.

Maybe what works in FSX needs tweaked in FS9.  I've noticed this in moving aircraft between the programs.  No idea why...  Sad
