Thank you very much for your suggestion.
Yes, the main spar better can located on the CG position and this is my original design.
But this is not success on the foam molding for some of reason (can't tell at the moment.)
I may try to slove this problem on next lot of production.
About the warping issue, one of the solution is use new PN material.
That is something between EPP and EPS but not EPO.
You will see this materail using on F-35 very soon.
Keep you comment in, thank!
