Thanks for the info on Arrma. We've been looking again this summer because our 3yo's taken a shine to my Q32.
I've let her run it several times in the garage. The foam tires are great. I remembered seeing the carpet racers using little sponges and squishing their tires over them a bit. Splashed a tiny bit of water on the slick concrete, let it flatten. Ran it through there and whaddya know? Better grip, and the front didn't push no more.
Never ran an 1/8 scale on foams, but they do have em. Should help to protect those (replacement) wheels. Wear may be an issue, however. Lol
