Brushless setup for E-Revo ???

[Serum]

I am using the 7XL with the 9920 too.

According to Mike, The quark 125 seems to be smoother, but the 9920 is smooth as butter already.

If you want to go lipo, get a 4S2P pack (8000 mAh in total) but with the 9920 you would need a separate lipo cutt-off. the 125 has got one build in.

The 7XL preforms very well on 14 cells! on 12 it's quick, on 14 even better..

About the standard revo-rims;

Glue the hex in with CA glue.. they won't last too long if you don't glue them.

About the smoothness. How often do you drive 0.1 mph? the startup with the hv-maxx is as smooth as possible. But the 9920 has got low cogging. (cogging is a startup every non sensored BL set has) but with normal driving i can assure you, that you won't notice it.
