Hi All,
I haven't raced 1/12 in a couple of years and can't recall what rollout was typical for an indoor medium-size carpet track with 10.5 motor (boosted).
My search results seem to reveal that 50mm plus or minus a couple mm is ideal, but I have also heard as high as 65mm.
Just hoping for a few more people to chime in before I order pinions!
Thanks,
Kane
