This will be an interesting thread once syscom finds it. He will come in here about Budweiser will blow away anything from Australia, New Zealand and the rest of the world.
People go to great lengths to build a scale lancaster bomber and screw the pooch with the glasshouse.
Read my lips, it isnt a total outside frame unless you are doing a Mk XII Canadian assembled late war Lanc.
Photo 1 shows the normal stuff up made. The outside of all the frames are painted in camo colours. (forget the fact that Hasegawa put the escape hatch 1 frame too far forward)
WRONG
From the second large side windows back, the horizontal frame and the last vertical frame before the astrodome were Black and Inside the canopy itself.
The whole section at the back of the glasshouse was made out of Spruce wood not metal. Thin Ali strips were used on the cross frames on the outside bolted through the perspex and spruce frame underneath.
The rest of the pics are from Air Publications and real planes.
Easiest way is to use clear transfer material and spray paint it black, then set thin strips on the inside of the canopy on the correct lines.
Sand off the existing external frames from 600 to 2000 grit sandpaper and finally polish out scratches with toothpaste.
When you mask off the external framing of the canopy, shoot flat black first, then your canopy colours. This looks "Normal" now when viewing the canopy as they had black interior framing.
