This may be a silly question that I really should already know the answer to, but, how does one easily remove the flashing? I tried sandpaper, and maybe it was too fine, but it was not doing much at all. I would not mind if my F2 flew like an Eagle and not a Trident/Pred.
get a sponge/sandpaper block, about the size of a pack of cigarettes. sand away. the sand paper will give you the smoothest and most consistent result.
