this is not my day. i know that i have seen this issue address somewhere, but here's the problem, the gearing wheels of the polikarpov are sinking in the runway. i seem to remember that the solution include some minor changes in CFG file, but dont remember where to look. image in freeware screenshot. thanks

looks like a [contact_points] problem?!

Maybe try rising this:

Code: Select all

static_cg_height=x.xxx

meck, i tried many combinations with no visible results.hagar i red the post but the solution was way over my head. thank you both. the plane fly very well, i will keep it like that for the moment. see you.

I had a little fiddle around with it. It's not perfect but a lot better than it was. If you you would like to try it copy the complete [contact_points] section I've pasted below & paste it into the Polikarpov Aircraft.cfg replacing the existing entries. Please take a backup copy of Aircraft.cfg first.

This is the result.

thank you hagar i will try it at once.

unfortunately it didn't make the trick, it just sank half the plane into the ground. thanks anyway. as i say i will keep it like it for now.

I suspect you didn't do it correctly. That's why I told you to take a backup copy first.
