Will this new chassis be included in new kits, or purely an option part at this point I wonder?

Out of curiosity & because I can't find any description other than "X-Gear", what body is David Ronnefalk running on his RB6?

I'll assume the idler gears you're talking about are the new alum ones.?
If that's the case, you going to run two alum idler gears or just one? I'm thinking that going with just one might be the way to go. As in, top shaft, plastic idler gear, alum idler gear, plastic diff gear. Basically a metal/plastic/metal/plastic setup. Just checking if that's the way to go or not.
