Thanks Guys, the other side cracked too....in 2 places... the worst was right through the middle of the Blue and white checker on the curve of the fuselage, boy did I swear.
removed the larger broken upper section and cut it directly along the edge of the checker pattern and then fitted the broken piece as best i could on the curve, got it pretty good but still visible as you can see in one of the close ups below...then i applied the upper section of the checker right up against the other section where i cut it that went on no problem until i had to get it to conform in the upper front section of the tail then it split again so more work there....other decals went on fine.
I'm considering just buying another set cutting out the squares and overlaying the damaged sections with new squares...I will never match that blue colour with paint....
Added the tadpole decal also didn't quite line up perfectly along the front edge of the vertical stab so added a bit of RLM70 with the brush, once this is glossed over it will blend just right.
i also determined that I had also used the wrong rudder....was going to leave it but the early 262's had a clear covered light on the bottom of the rudder and even though most of the 'tadpole' decal would cover it and it wouldn't be noticed I had to correct my oversight, so out came the small razor saw and i removed the corner section to put the clear one in place, will get that sorted tomorrow.
