[GorillaMaxx360]

36t should fit i would go with the mamba monster maxx when it comes out the way they are talking about this thing you can easly push your car to 45 maby 50 with this gearing IMO becasuse they said they where getting like 50+ out of a 14 pound maxx so that is pretty good as for now going with a higher rmp motor like brian said like a LMT's. I know though when i was doing the same thing for my maxx awhile back i was trying to go 40mph with slipperential and 1/8 hb diffs. With my maxx and using the speed calculator i came up with 41.82 mph using 1/8 scale Buggy size HB diffs, slipperential, 36t spur, 20t pinion, 14.8v which is 4s, kv or 2148 which is the feiago 7XL rpm, 5.80 tire radius which is the radius of crime fighters, and that is it and i achieved 41.82 which is pretty good with slipperential and 1/8 diffs i hope i helped.
