Thanks Patrick...

I most definitely will be wanting to run 9s on the 1520.
Due to my savage now being more of a fatty since i have added the GH Alloy Bulks and put the lipo boxes back on... i have had to gear the top end down a bit to keep the truck from getting hot. So i now need to run more voltage to get my desired speeds... so i will definitely be wanting to run 9s.

Patrick, i know that these neu motors are well made, and i have heard people running 10s on a neu 1520! obviously this exceeds the reccomended RPM.
I used a calculator and have the figures here assuming the following.

Neu 1520 (1600 kv)
Motor Resistance = 0.008
Current draw = roughly 120 amps?

Voltage Vs Rpm
Voltage---@3.7V-------@ 4.2V
8s--------45,824-------52,224
9s--------51,774-------58,994
10s-------57,664-------65,664

If i can i would ideally like to run 10s and gear my top end down to compensate.
I have heard of few people running their motors on the limit like this with no problems.
Do you think this would be ok to run? obviously i would expext premature motor failure...

What do you think?
Your advice is more appreciated
Thanks

Josh
