because of the stiffness of the std r1 chassi i turned on the dremel and worked off a little material from it, its still stiff!
will get the s1 chassi and topdeck in the mail tomorrow, looking forward to try it out
on the r1 chassi i have removed the little carbon piece between the 2 openings in the rear, extended the hole in the front and milled out between the 2 holes in the middle, its also narrowed down to 84mm wide
