Well chassis didn't survive beating in Austria. It broke where rear pivot blocks are screwed as there was hole under gearbox.
Anyway it seemed to jump very nicely and was stable in the air. I still preferred my Cougar. Carpet wasn't high grip and it lost rear end when you tried to brake very hard at the end of the straight.
Now I'll be considering if I want to make another chassis for summer. I've proven that this concept works very well and it handled nicely without much setup work (well basically none

). I call it success
