What ratio for E-maxx + Feigao 9l ???

hello friends,
I just have had a first run with my feigao 9l + warrior 9920...
I was disappointed about the lack of speed!!!
I run the Gmaxx 1 gear setup, 2x7cells, big joe 40 series tires, and for this first test I mounted a 16T pinion with a 70T spur...
My tx is a XS6 Race from Graupner...

Can someone help me to find the right gearing ratio to make my Maxx a rocket??? :028:

All thanks!
Fagzz.

Are you disapointed with the lack of top speed or lack of power?

More top speed... Go up one or 2 on the pinion or down 2 or 3 on the spur.

More acceleration... Go Down 1 or 2 on the Pinion - or Up 2 or 3 on the spur.

If anything stars overheating, go back a tooth or 2, you have reached the limit.

According to my calculations the setuo you are running should be around 37mph top end. If you go down to a 14 tooth, its around 33mph. Up to 17 tooth, around 40mph. Although you are probably reaching the limits at 70/17 if you can run it there without overheating.

I have a emaxx w/ the same motor and esc. I run 66/16 (Almost the same ratio as 70/17) and its about all it can take. I have to run a fan on both the motor and the esc to keep it cool. Mines pretty heavy though. It mign not be as bad if yours is lighter.

Over gearing can slowing down as well...

i only have 16, 18, and 20T pinions for my feigao... do you think that I can use a drilled 3mm pinion in place of the 5mm bore ones from Kershaw? if yes i can drill all my old HVmaxx pinions...
Let me the time to try, i just have woke up...

Acceleration is awesome, but top speed is very slow... my hvmaxx was really faster...
