an old bug about the Mk IXc and the Mk IXe
the in game the Mk IXc have wrong rudder and the Mk IXe have wrong wheels. Late production series airframes, typically Mk. IXe and Mk. XVI, were often fitted with the larger, pointed Mk. VIII-type rudder. Four-spoked wheels seem to have appeared in Mk. IX production during 1944, typically on Mk. IXe’s. Three-spoked wheels are mostly seen on late-production Mk. XVIs.
