excessive bouncing the dreamwings Dash 8-100 model

[acela2036]

Hey All,

So I recently just downloaded the Dreamwings Dash8 model and then when I go to taxi and head down the runway, the plane has an excessive amount of shaking. Basically its the same thing when your going really fast in a fighter jet and then your plane starts to shake violently. Anyone know how to fix the excessive bouncing and shaking?

Hello,

Try those contacts points (aircraft.cfg)

[contact_points]
point.0 = 1, -5.0, 0.00, -7.70, 1500, 0, 1.617, 25.0, 0.500, 2.5, 0.9, 5.0, 6.0, 0, 100, 250
point.1 = 1, -29.0, -12.99, -7.90, 3000, 1, 0.633, 0.0, 0.675, 2.5, 0.8, 6.0, 7.0, 2, 100, 250
point.2 = 1, -29.0, 12.99, -7.90, 3000, 2, 0.633, 0.0, 0.675, 2.5, 0.8, 6.0, 7.0, 3, 100, 250
point.3 = 2, -31.6, -42.50, 5.39, 1200, 0, 0.000, 0.0, 0.000, 0.0, 0.0, 0.0, 0.0, 5
point.4 = 2, -31.6, 42.50, 5.39, 1200, 0, 0.000, 0.0, 0.000, 0.0, 0.0, 0.0, 0.0, 6
point.5 = 2, -68.6, 0.00, 1.22, 1200, 0, 0.000, 0.0, 0.000, 0.0, 0.0, 0.0, 0.0, 9
point.6 = 2, 0.0, 0.00, -3.92, 1200, 0, 0.000, 0.0, 0.000, 0.0, 0.0, 0.0, 0.0, 4

max_number_of_points = 21


static_pitch = 0.08 //degrees, pitch when at rest on the ground (+=Up, -=Dn)
static_cg_height = 7.2 //feet, altitude of CG when at rest on the ground
gear_system_type=1 //Hydraulic

And also this:

Moments of Inertia
empty_weight_pitch_MOI = 111701
empty_weight_roll_MOI = 61201
empty_weight_yaw_MOI = 161691
empty_weight_coupled_MOI = 0

Regards.

Thanks for the attempt, but now its super bouncy

Thanks for the attempt, now I get this and my aircraft starts zooming along the ground like a rocket and hard to stop
I Actually found another thread with the same issue

Thanks for attempt guys

RE: Dreamwings Dash8 100/200 - Simply Spectacular!

Don't remember where I found it but the change in the aircraft cfg to eliminate bounce is to amend point.0 under the contact points section:
point.0 = 1.000, 26.000, 0.000, -6.700, 3000.000, 0.000, 0.500, 55.000, 0.200, 3.500, 1.000, 4.800, 4.800, 0.000, 0.000, 0.000
It worked for me.

So .. it's seems the Mowgli22 solution must work !
Mine above was for another Dash .. sorry for confusion !!

Regards.

problem solved!

Never flew the Dreamwings DH8 but I have been flying the Majestic DH8 for a number of years and it does not show any signs of excessive shaking or bouncing. It handles like a DH8 is supposed to. What did you do to solve the problem? btw, if you want to get a good landing all the time, land with Flaps 15 and the props at 1050.

problem solved!

yes, could you please post what solved your problem, it may help others in the future.

[napamule2]

collotty,
You did not say if you have the DW Dash-8 and had any bouncing or shaking. And if you do, you don't say if you TRIED THE SUGGESTED CHANGES. If you did have it and then tried the 2 suggested fixes you would find out if (and when) they 'worked' (or not).

So the nose wheel compression ratio was wrong (ie: '.., 0.200, 3.500, 4.000,..'). The '4.000' should be from '0.900' to '1.000'. That took care of the 'bouncing'.

The MOI's, for 'pitch' were too low (ie: '98556.000'). The increase to '111701.000' produced a suitable 'change' to reduce (the appearance of) 'shaking'.

That was IT (trust me). I doubt if any other changes to cfg or air would make any difference, or improve it any further, so I'm guessing there were no other changes made. But the OP can correct me if I am wrong. Where did he go? He is obviously off flying the Dash-8 and is not aware 'we' were left in the dark (hehe).
