Kangooroo Jumping GMax Mirage 2000

[VaporZ]

Sorry to bring back this topic but ....

can somebidy propose me ( us ) a tweak for the CFG File to
cancel the "Kangooroo Jumping" effect on the GMax Mirage 2000
series ?

I have tried all approaches type landing on all Mirage 2000 versions
including aerodynamic "tail drag" landings and its continues to jump like
it is "full brake" on 3 wheels on touch down.

The kangooroo jumping is stopping at around 97 knots.

And please .... before somebody told me "learn to fly first" be advised
that I flightsim for now 8 years on both FS9 and FSX and I have accumulated hundred of FS hours on :

Tutor, T-33, Hawks, Texan II/Harvard II, T-45 Goshawk, Aero L159, etc...
plus

Aerial Foundry CF-18
Kirk Olsson Mirage F-1 and F-16
AlphaSim Hunter
Super Etendards
AlphaSim Gripen
Fouga Magister
Alpha Jet
Jet Provost/Strikemaster
etc....

plus FSX Lotus L-39C, Skysim Mirage III/V, etc....

and I can do super smooth landings, including on Aircraft Carriers.

No offense to the developpers they have done a very good job
but of all the hundreds of paywares and freewares I have, the only
"jumping on landing" problem I have is on the GMax Mirage 2000 serie.

Thanks for the help !

I found a very bizarre trick to resolve the "Kangooroo Jumping"
syndrome of these Mirage 2000 :

On the CFG file there is seven lines of programing on the
"Contact Points" chapter ( from Point 0 to Point 6 ).

For the single seaters Mirage 2000C, 2000E and 2000 5F, I have delete
the original seven programing lines from GMax Ac and I have replace them with those of Kirk Olsson's F-16 Viper CGF File ( !!!!!!!!!! )

And it works !
No more "kangooroo jumping" on landings.
End of story

Hi,

Seem's odd .. but will test it.
It's ages I don't fly more those planes cause the jump on landing!

Edited

Tested on the Gmax Mirage 2000D

Lol .. it's work (no more jumps) .. but I had to make some changes on the gears contact points:
Put the main gear backward of the gravity center and also up all the wheels a little !

With the Viper not modified :

After the modifications

point.0 = 1, 10.583, 0, -6.7, 1574.803, 0, 0.978, 37.62, 0.12, 1.7, 1, 6.3, 6.2, 0, 400, 0

Hello Claudius24

my first message was mentionning a modification only for the SINGLE SEATERS Mirage 2000C, Mirage 2000 5F and Mirage 2000 E.

GMax Twin Seaters Mirage 2000 N, Mirage 2000 D and Mirage 2000 Exports Twins never had any "kangouroo jumping problem" at all, they are perfect from the start...

and contrary to the single seaters with 7 lines of programming they have
a 8 lines "contact points" programming from point 0 to point7. its not the same.
:mixedsmi:
Best regards

Hi,

Oki doki (so much Mirages !!)

So I take this Mirage
description=Mirage 2000 C modélisé sous Gmax Laborie Roland, rollus13ATclub-internetDOTfr
atc_id_color=0000000000

And put in the aircraft CFG those contact points values from the Kirk VIPER

point.0= 1.000, 10.583, 0.000, -6.420, 1574.803, 0.000, 0.978, 37.620, 0.220, 1.700, 1.0, 6.300, 6.200, 0.000, 400.000, 0.000
point.1= 1.000, -2.500, -4.167, -6.670, 1574.803, 1.000, 1.000, 0.000, 0.605, 1.300, 1.2, 5.5, 5.600, 2.000, 400.000, 0.000
point.2= 1.000, -2.500, 4.167, -6.670, 1574.803, 2.000, 1.000, 0.000, 0.605, 1.300, 1.2, 5.5, 5.600, 3.000, 400.000, 0.000
point.3= 2.000, -6.417, -16.333, -0.167, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 5.000, 0.000, 0.000
point.4= 2.000, -6.417, 16.333, -0.167, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 6.000, 0.000, 0.000
point.5= 2.000, -19.750, 0.000, -1.833, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 9.000, 0.000, 0.000
point.6= 2.000, 22.667, 0.000, -1.250, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 4.000, 0.000, 0.000

The result was

So I corrected the contact points and the result was

But when applying brakes I had also this bad result

So I corrected more contact points parameters and the result was very good

Under are the final contact points correction

point.0 = 1, 10.583, 0, -5.47, 1574.803, 0, 0.978, 37.62, 0.12, 1, 1, 6.3, 6.2, 0, 400, 0
point.1 = 1, -2.5, -4.167, -5.51, 1574.803, 1, 1, 0, 0.405, 1.3, 1.2, 5.5, 5.6, 2, 400, 0
point.2 = 1, -2.5, 4.167, -5.51, 1574.803, 2, 1, 0, 0.405, 1.3, 1.2, 5.5, 5.6, 3, 400, 0
point.3 = 2.000, -6.417, -16.333, -0.167, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 5.000, 0.000, 0.000
point.4 = 2.000, -6.417, 16.333, -0.167, 1574.803, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 6.000, 0.000, 0.000

Hi,

I just retested all the problematics Gmax Mirages with your contact points findings .. and all is now perfect.
It's amusing to remember all the fuzz created about with the Gmax guys ..
In fact it was not a bad usage ( hard landing and tutti quanti) of their models (as some answered) but a deffect in the plane(s)
I'm happy you find it .. maybe by coincidence .. but you find it.
I wonder if they will correct theirself those planes with the new contact points ??

Answer 1 :
To put Kirk Olsson's Viper contact points programming on GMax
Mirage 2000 was a pure gamble. And it worked !!!

Quote 2 :

Answer 2 :
No. Impossible. They will had to admit a mistake !!!
