I have not been able to find a cure for the P-47 gun bug.............. I have been helping SAS Monty test the CFM (Compressed Full Monty) for it's release. I have the same bug in that as I do in the HSFX install. The only planes effected are the P-47, P-47D, P-47D-30, but all the B, C's and P-47D-40, P-47M-1 and the P-47-N all work correctly. So you can use the D40 for bubble top missions since all the D's are from 1944...........................
