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?

It will take 0.5 degrees of toe out of the rear. That is the way you would do it.
