For a spur gear, if you go smaller it has the same effect as running a bigger pinion. If it's already too fast, don't get a smaller spur or bigger pinion.
So leave it at 83 spur and 27 pinion but run a 2s lipo instead? that can work I mean at 50% its already so quick i'm sure the 8.4v the 2s will put out will give it plenty of speed, add control and stability while reducing amount of heat produced with a 3s.
