My copy of Mirage AX had a backplate on the wing assembly put together rather poorly from factory which made it look real gappy. It has been bothering me until today my OCD has taken over.😆 At the same time I added some colors to the missing detail, thanks to much needed tips from @Lolicon. For those who wish to disassemble the wings for whatever reason, there are 4 screws underside that are hard to miss. Simply undo the screws and wiggle out the entire back piece. The only thing will get in the way is the folding arm connecting the gunpod, just got to find the right angle and carefully slide it out.
