How about a 11xl, or anything else large with about 1600kv, like a 1515?
I am going to run a KB45 8xl, 1700kv, on 6s lipo in a crt conversion. Should be a bit lighter than your savage though. I have the same savage as you and will most likely use a 14xl on 8s lipo.
Linc, have you ran your kb45 8xl yet? I am looking into getting on for the savage. Needs a boost in power.
