This model was not originally designed for repainting but it is possible to change the colours.
All textures are DXT3 format and you will need a utility like DXTBMP to alter them.
The following textures are associated with the these parts:
ETCowl_t.bmp
The engine cowling.
Fabric_t.bmp
The rear fuselage.
Fins_t.bmp
The little fins on the tailplane.
Mudguard_t.bmp
The stripe on the floats.
Panels3_t.bmp
The forward fuselage, the floats and the forward float struts (U/C legs).
Parts_t.bmp
The fuselage step, the headrest fairing, the elevators, the skeg and the rear float struts.
Polished_t.bmp
The float bottoms and the clamps at the rotor roots.
Struts_t.bmp
The rotor mast and fairings plus the lugs at the base of the windscreen.
FinL_t.bmp
The left side of the central fin.
FinR_t.bmp
The right side of the central fin.
The other textures aren't too difficult to figure out.
Note that the fuselage and U/C textures are mapped cylindrically whilst the rest are simple planar maps.
Have fun. I look forward to seeing your work.
