ive had this problem before...

[darrenvox 138]

using the PAD dash 8 q400 ive used it before and had this bouncing problem not while starting up but while taxiing if i speed it too much. im sure ive found the answer in my past but i cant seem to have found it, i tried looking on my forum/blog and emails to the PAD group and nothing comes up with the answer...so does anyone know where in the aircraft.cfg it is located ro change or fix the problem...it must be contact points area

 

heres the current one

let me know soon

I would actually be extremely interested in the solution to this also. I have the same exact problem with the POSKY 737-800, especially on take off roll. Sorry I can't be of any help Darren.

found the email i sent the PAD people and heres the contact points to fix

Wow..... your gear positions were well out!

Have you checked these two? They are almost always incorrect.

static_pitch = -0.200
static_cg_height = 10.200

will do in a few..

Darrenvox,

Bouncing during taxiing and/or when on the runway can also be caused by the the surface texture being used on either or on both. Yes, it's strange but only concrete and asphalt surface textures are smooth while (almost) all others seem to be structurally "bumpy".

In the past I've been trying to solve this problem for myself but eventually just had to accept defeat.

Regards and good luck.

I do not have the aircraft so I cannot say but I can tell you how to do it.

Go into slew mode (default keypress is Y), slew down (I have assigned a button on my yoke for this...I'm not sure what the default keypress is for this)  until the aircraft will not get any lower. Then keypress Y to come out of slew mode. if the aircraft rises or get lower your static height is incorrect.

Keep adjusting this figure in the aircraft cfg until there is no difference in height (or pitch.... that is what the static pitch is for) in slew mode or not.

This is essential if you use AES for pushback. It also good for smooth landing/taxi etc.
