Hi,
Here is a rough first sketch of the plane I intend to try and build.
It's meant to be about the same size as a WWII dive bomber with a "cranked" leading edge to the wing, like a Vultee Vengeance, and a twin turret aft, like the early Brewster Bermuda concepts (or an A-20G).
[Vengeance (L) & Bermuda (R)]
[A-20]
In addition, although it is meant to have a radial engine and a tail dragging layout, the wings will have a slight inverted gull shape, and the fwd cockpit canopy will have a "bulged" Malcolm hood like shape, similar to the post war Fairey Gannet.
[Gannet]
The main landing gear will also retract inward from the wing bend, kind of like the Gannet, and the tail will have three vertical parts, though the overall shape of the empennages, and the wing tips will be rounded, kind of similar to the Bermuda.
And finally, I also intend to put on a detachable cannon under each wing kind of similar to a Vicker's S Gun pod, shown below.
Regards
Pat
