About time to design a new chassis then
Maybe two saddle packs?
BTW, I noticed one thing while fiddling with this and some body issues, I have, and that was the fact that the "old" X6 and squared chassises are not the same shape in the rear corners. I used an X6 shell on my squared chassis, and saw that they dont have the same curvature in the rear. Are the shells different also? Was this intentional?
