Hi Stephen ,
The gun does look menacing and I can just image what the recoil would be . Most of the pit will be visible when closed up . The canopy is all glass .
The pit is done and installed in the airframe and closed up . While that was drying I made a start on the engines and the landing gear/wells and was even able to get those parts painted up . Once dry the weathering can start finishing with the assembly . Other items are also ready to go as well , landing flaps , cowlings and the rads in the lower wings are per-assembled waiting for painting and such just didn't take photo's on this . Tail planes and rudder are fix in place .
