I think I'm gonna go Mid Motor ... a guy I race with at TopGear Hobbies in Portland swears by it. He says the car seems more predictable and is easier to drive overall. Does anyone have a MM setup that is really working for them on indoor clay? (gold barcodes all around is the tire that works) ...oh ya, I'm running mod w/ an 8.5

JC 7" wings are great, but the LMR are amazing IMO.

How well does the LMR wing fit?

Does it come with a mounting grid for the holes?

I've been using Schumacher wings. Precut and prepainted. Reasonably durable

Kyosho Aquariuos wing is the best I feel for the Rb6. Much thicker than those junk Jc wings that fold and deform just looking at them.

Not sure if this ok to do, but I have been running my RB6 on high grip carpet in the mid motor configuration. I want to take out some of the rear toe. Is there a way to do this yet? Or do I have to wait for the new adjustable hangers to be released?

I was gonna try using the .5 degree hubs on the opposite sides (putting the right on the left and left on the right) I just don't know how much of a change I'd be making. I tested it out on my table and the shocks are still super smooth and the toe in looks less drastic. Any thoughts?
