In every case where I install this awesome jet the canopy stays open during flight when viewed from the external cameras. I went in my F-23A located in my case here, C:\Program Files (x86)\Wings Over Europe\Objects\Aircraft\F-23A. I opened the F-23A DATA.ini file with notepad and located the Canopy settings. I don't write software or anything like that but I noticed both the Deploy and Retract values were the same set at 10.0. I changed the RetractValue to 11.0. It worked. If you have the same problem try this fix.
