I tried using it and when i squeeze the trigger everything freezes. so i need a tutorial badly

DPED V. 0.9. Its on this site. I dont know who made it though

The best advice I can give is to open the DP file of a similar 3rd party aircraft in DPED to use as an example. You can gradually modify it to suit your own requirements. Take it slowly & don't try to do it all at once.

Paste a copy of any existing DP into your aircraft & use it for your experiments. Rename it with the same file prefix as the AIR file of the aircraft it's for. Don't forget to delete the corresponding CDP file every time you modify the DP.

PS. Unfortunately Yusaku Homma speaks very little English. I don't remember any specific tutes being written for his amazing DPED. It's not that difficult to figure out, especially for CFS1.
