Hi, I am starting to learn FSDS and made an acft with retractable gear, All works fine except the wheels are half way below the ground surface. I can't find anything in the help files on this and the tutorial didn't say anythig about it either. If I go into FSDS and raise the acft in relation to X axis, the acft and gear move together, but in the sim only the acft raised up. the gear are unchanged and now detatched from the acft. Please Help.
Thanks
Joe

Joe you need to change the contact points in the aircraft.cfg file

There are two ways to solve that problem, either go to FSDS or whatever you're using, select the model and click the "Move" button, or whtever it's called (I use GMAX), move up and try to see if it works.

The other is what the last  person told you to do. Adjust the contact points. If you don't know about contact points, "Contact" me  ;D and I will show you how.

I had this problem with my truck project that I abanded.

thanks for the replies, I will need some help with the contack points as I don't know which ones do what. When I tried to move it in FSDS the acft moved but the gear stayed the same.
Thanks

When creating your model in FSDS did you create the series of reference parts (gear.center, gear.left, gear.right and the other scrape points)?  WHen you do this, these reference parts are not compiled, but their locations are written into the [contact.points] section of the aircraft.cfg file.  MAke sure, when compiling your FSDS model that you click on "process reference parts".

ok I'll try that thank you very much.
