Hi,I had the same issue using the IFly SP 2.0 updated via ZIP-Update to SP 2.1. I deleted all FSUIPC controls for the flaps, but the F/O always set Flaps to 40 even if he replied the correct take off setting, e.g. flaps 5. Finally I uninstalled FS2Crew, deleted all the remaining fs2crew folders, uninstalled the ifly737, deleted all the remaining ifly737 folders and did a new clean install of the full SP2.1 version and finally reinstalled fs2crew, Now it works pretty fine.Best regardsStefan.
