There is definitely something wrong with the trimming in the piston Duke. Ryan, I hold the utmost respect for you, but using a trim button in an aircraft with a trim wheel is not the answer. I was told this same thing regarding this wild pitch issue in the 414.
With the 414 it was a simple fix by downgrading to a previous version. FlySimWare still denies there being an issue, even though my Saitek trim wheel works perfectly with their earlier release.
