contact point problems

[BoeingvsAirbusNKL]

I have been messing with the contact points for Bismarck13's D520.

When i think i got it, it rocks like a rocking horse.

Bismarck, i'll post the contact points here

point.0=1, -23.21, 0.00, -0.60, 3200, 0, 0.30,180.0, 0.40, 2.5, 0.80, 7.5, 5.00, 0, 0, 135
point.1=1, 4.41, -5.76, -6.55, 2200, 1, 1.05, 0.0, 0.50, 2.5, 0.83, 2.5, 4.00, 2, 0, 135

point.5=2, -20.25, 0.00, 1.00, 2400, 0, 0.00, 0.0, 0.00, 0.0, 0.00, 0.0, 0.0, 9

Can you or anyone give advice or modify it so it doesn't rock like a rocking horse?"

Keep working at it.If at first you don't succeed try try again. That's the only way you learn how to do things.

TAlon thanks for your comment.

I actually found a winning combination last night.

Watch out, once you get started it can be hard to stop.

See that 180 in RED, Boeing ?

That's the turning radius for the steering.....

If you lower that number to 35 - 40.0, your A/C will be a lot nicer to taxi.....

Try it - you'll Like it....

Tried it sc7500, works fine.

But the plane is shaking on the ground and rocking when the tail wheel touches down.

Any tips and tricks?

[sc7500]

Sometimes they hop around because the CG Height is too "High":

[contact_points]
static_pitch = 12.233
static_cg_height = 5.907
tailwheel_lock = 0
gear_system_type = 1
max_number_of_points = 7

Try lowering or raising this number in 0.050 increments and see if the hops dissipate...

static_pitch=14.624023
static_cg_height=4.847077 <-- The winner

I KNEW you could do it, Boeing !

Take a Break - you earned it.

thanks sc7500.

Alright, I have fixed the rocking but how do you shaking on the ground? It shakes when it starts up.
