My attempts to built a Sopwith Tabloid and a Schneider.
Both started life as Airfix Pups.
The fuselages were reshaped using plastic sheet and Green Stuff two part filler for the noses.
The wings were filled, the shape altered, the ailerons filled and the re-scribed.
The tails were remodelled from plastic card and the spares box.
The floats were scratch built from plastic sheet. The supports are a little think, but I was going for strength.
Structs are from aerofoil section plastic.
