I have trouble with Add-on #3 True-scale version. None of the aircrafts worked. Most of the time whenever I advance the throttle they just sit there or some of them just barely roll, they do not have enough rpm for take off. Please let me know if anyone has suggestions how to fix this. Thanks!

and yes, patch version 1.11.07 is installed

Hi Joe, pls let me know your system specs, and your tmlog file which you can find under the AFPD directory and open with a text editor like notepad or word. Thanks
