ran a 7.5s on LiPo @ York on 24/81

same pinion for 84 won't be that far away.

for 6.5 go to 23/81 / 84

81 is kit spur

I run a 23 on a kit spur with a 6.5L EVERYWHERE (on the B4 and now S2).

The 6.5L is just such a versitile motor

What goes for a Losi xelronin 6.5 sintred? I use 21/84 now but can i go 22-23/84?

How hot id your motor after 5 minutes?

[Alex H]

Quite hot acctually. Thats why I´m asking because it woulnt be any cooler with higher gearing. Do you guys all run lipos? I am not so far but thinking about it since its being aproved by efra. I have heard that lipos makes both motor and speedo run cooler than with subC´s.
