@Oicraftian ehhhhhhh,you dont understand,its just a decorative cammo

The difference in the two statements is the presence of camouflage and the choice of camouflage. In which case I would have to say it is the first thing I changed (to Prototype Grey) when I downloaded the aircraft due to an inability to distinguish features. If you want "night fighting" it is better to paint in varied gloss with different colors instead of a hard black and red scheme. For a daytime scheme it simply stands out too much.

@Oicraftian ummmm.i just call it camo,but does it looks pretty

My pleasure. For camouflage? For "the" camouflage or for "a" camouflage?@kukimuki1234

@Oicraftian thanks,and by the way,what do you say for cammo

One option is to manually replace the wings with hacked structural wings with control panels. This is probably the least difficult way.
Another is to alter the coding of the parts to ignore stress like structural wings, which is far beyond regular levels of redundant and much more difficult.
A final solution is to cut down on the P/W and use structural wings for the inboard wing form whilst using wings for the outboard sections making it better able to resist this problem by reducing the amount of points at which it bends.
These are the solutions that should be available to you. @kukimuki1234

@Oicraftian so what i can do

Basically it has to do with the wings bending when you try to pull a turn. It is a problem due to your high P/W which increases the stress on the wings and their great side. I also noticed you "squished" it width-wise.
