Aircraft fly as AI

Hi,
Have recently downloaded B17 (Fuddy Duddy) and want to use it as AI aircraft only. Unfortunately after plugging it into TTools and creating flight plan, the aircraft behaves well until it is going for landing. During approach it sways from side to side, usually hitting the wing first on landing, sometimes even missing the runway. I have increased the empty weight in aircraft config file and it only slightly reduced the swaying on land. Anyone knows what else to adjust in config or air files to make the aircraft land properly?
Many thanks for any help.

The aircraft config file is attached for info.

description=The "Fuddy Duddy" is a wonderful B17 that was at one time stationed at Elmira,NY at The Wings of Eagles Museum. I have had the privaledge of walking through this aircraft and was amazed how cramped the crews must have been. The "Fuddy Duddy" is one of the few remaining airworthy B17's and frequents the air show circuits across the country. Now stationed in California.
