help. (Brushless savage)

[Serum]

I really, really don't understand it anymore.. I am missing posts on and on and on.. I start reading thru the forums and found this one too.. I am sorry for not answering this question (and much other questions i am missing somehow, i threw away my cookies, i guess that's the catch...

But, in order to give you an anwer; Did you tested it allready?

The 12T pinion is good to begin with. You can always drop in a 49 tooth spur, but try it first. If you are going to run it with the GT tires, (stock tires) you will suffer a nasty balooning.. on topspeed you might use a 100ft wide road, because it lives a life on it's own with this tires..
