Actually I just pm'd him the email addy of the individual that assisted me. Just on the off chance he gets a response. I found the IRIS folks quite helpful.There were no mods-just a recommendation of what to try and the reasoning for the "unassisted" bank angle changes in level flight. While its not perfect it is manageable and more important-expalianed and expected behavior.Hope the OP gets it sorted. It's a pretty sexy aircraft with very interesting engines (I guess you love it or hate it).
