Hi,
I've done a quick conversion of Miljans Hermes 450 but have an issue with the contact points.

This model is another "bouncing Betty" at low fps or if I increase the sim rate.

I tried adjusting the static compression ratio (dropped it as low as 0.5 and as high as 5.5) but with no change in the behaviour.

Does anyone have any other suggestions?

This is the contact points section

[contact_points]
//0 Class <0=none,1=wheel, 2=scrape, 3=float>
//1 Longitudinal Position (feet)
//2 Lateral Position (feet)
//3 Vertical Position (feet)
//4 Impact Damage Threshold (Feet Per Minute)
//5 Brake Map (0=None, 1=Left, 2=Right)
//6 Wheel Radius (feet)
//7 Steer Angle (degrees)
//8 Static Compression (feet) (0 if rigid)
//9 Max/Static Compression Ratio
//10 Damping Ratio (0=Undamped, 1=Critically Damped)
//11 Extension Time (seconds)
//12 Retraction Time (seconds)
//13 Sound Type
//14 Airspeed limit for retraction (KIAS)
//15 Airspeed that gear gets damage at (KIAS)
// 0 1 2 3 4 5 6 7 8 9 10 11 12 13
//Default FS9 gear settings
point.0=1, 7.00, 0.00, -2.675, 1500, 0, 0.25, 22.0, 0.1, 2.5, 0.7, 0.0, 0.0, 0
point.1=1, -1.10, -4.50, -3.150, 3500, 1, 0.40, 0.0, 0.1, 2.5, 0.7, 0.0, 0.0, 2
point.2=1, -1.10, 4.50, -3.150, 3500, 2, 0.40, 0.0, 0.1, 2.5, 0.7, 0.0, 0.0, 3
//Increased static compression to reduce bouncing behaviour in P3D
point.0=1, 7.00, 0.00, -2.675, 1500, 0, 0.25, 22.0, 0.1, 5.5, 0.7, 0.0, 0.0, 0
point.1=1, -1.10, -4.50, -3.150, 3500, 1, 0.40, 0.0, 0.1, 5.5, 0.7, 0.0, 0.0, 2
point.2=1, -1.10, 4.50, -3.150, 3500, 2, 0.40, 0.0, 0.1, 5.5, 0.7, 0.0, 0.0, 3

max_number_of_points=4
static_pitch = -2.85 // degrees, pitch when at rest on the ground (+=Up, -=Dn)
static_cg_height = 2.8500 // feet, altitude of CG when at rest on the ground

Hello Gavin ,
I think you have old version , it was updated and reuploaded with settings provided by John Young , you can take a look here or download package again

Hi Miljan,
thanks for that - blame Martin I was using his conversion base pack.

Will try the updated settings and if all is well I'll return the package to Martin for release.

Thank you for making such great models, and thanks to John for all his insight.

Haven't tested Johns updates yet but I have an embarrassing admission to make.

When I inserted Johns updates I realised that I copied the contact points and tried adjusting them but (if you look closely at the contact_points section I posted earlier) I forgot to comment out the original FS9 settings, so all the changes I made were ignored

Still I'm sure Johns update will fix the issue.

Very sorry for your wasted time, I missed there was an update.

From mobile hence short

You know I was just kidding Martin. The time spent testing the contacts was trivial. I have the models converted to P3D standards (which was the difficult part) and will just double verify the contact points this weekend then upload.
