6s Revo. What Neu?

[Patrick]

Personally I would get the 1515 1.5Y for using 6s only.
You'll have to use 20t pinions and bigger with the 51t spur to get speeds over 40mph as it is with the e-maxx trans and 1/8th diffs. Using the 3D and even using a 25t pinion you'll only be able to gear for ~43mph.
The big pinions are a bit annoying to use, because the pinion is so big it covers the screws that hold the motor on, making it harder to set the mesh properly.
