Dave, I know exactly what you mean.
I'm building Revell's 1/72 Horton G0 229 at the moment, and having read the instructions, removed the nose wheel mount from the wheel bay. Just like it says to.......
.........only I missed that little question mark symbol!
Turns out you only need to remove it if building it wheels up!
See, even reading the instructions isn't enough.
Tanky, keep up. I left the IP out remember?
