Zuriel,
Your fuse looks very good. I have used this construction on a few ships. It looks like you have used at least 3/16" plywood for the mount wall, this is good. A few have tried to use 1/8" and found the motors would move, rear external bearings were used to stabilize this. With the thicker mount wall the rear bearing is not needed. One thing I would recommend is to use a couple 1/8" counter sunk wood screws through the plywood doublers into the center of the mount wall, then add the triangular stock, you could add the glass also. One thing we forget sometimes about electrics is that we still have the torque of the 46, or 60 size engine that is spinning the prop and must have structure to handle it.
Best, DennisT
