Here are photos of my progress on my Flying Pirate Alliance fast scout/reconnaissance craft
First off, float construction using sheet styrene and milliput.

Next, installation of main float, decal stripe on fuselage and engine/prop

Next, preparation for mounting wingtip floats

Floats temporarily stuck on to check for overall scheme, nice view of sharkmouth

Rigging completed, all floats installed, working on aircrew, and machine guns
Aircrew installed, machine guns, and working on final details
Final pics of completed model



Final notes -
The fuselage and wings are from an old Lindberg 1/48 Stearman Trainer
The propeller is from a Modelcraft 1/48 Noordoyn Norseman, the propeller spinner is from an Airfix 1/48 Hawker Hurricane mk.I
Floats are scratchbuilt
Piarate decals are handmade from white decal material from a Hobbycraft 1/32 Fokker triplane
Twin Lewis guns for rear gunner are from a Roden 1/48 Bristol F2B
Engine is from a SMER 1/48 Bristol Bulldog
Sharkmouth decals are from an Eduard 1/48 Roland C.II
Underwing machine guns are from a Hasegawa 1/48 Spitfire Mk. IX, housing origin.. I forget.
Hope you like it. Though not in the Porco Rosso movie, the model was inspired by it.
