Good stuff.
The inner stubs would be .50 cal guns, if fitted. These would be hollow, with either a red fabric patch or a cap. If the guns weren't fitted, the stubs would have the domed cap fitted.
One question Andy - does the kit include the 'standard' wing tips, as well as the 'clipped' tips ?
Might be interested in doing G-Fire, when it's released, which, when i knew it, had full span wings.
