Default First upgrades.

So besides the motor and ESC, which I would like to save for last, for multiple reasons. What should I focus on first? And whats a fast gear ratio. Can I use a Lipo 3s 11.1v on the 5700kv.

can't help with the gear ratio, but the stock S2 Flux esc and motor are only rated for 2S LiPo.

So 3s LiPos will kill the motor? but the ESC is rated to use 3s Lipos. What's the worst thing to happen to the car if i do stick 3s lipos in it? And if I upgrade the motor, things will start breaking under the stress added to it, So which parts should be changed before they break? and will the MOTIV ESC work for any brushless? Can I change the motor and use the MOTIV ESC or do i have to change the ESC at the same time. I'm just getting into this hobby. I got this as a hand me down and it had no batteries but i got some 3s lipos from another friend. So if someone can explain the "worst case scenario," that would be great.

Here is a great thread about the sprint 2 with a bunch of great mods and upgrades discussed. You can do 3s on the electronics, but its not recommended, the sidewinder has always had heat issues, but maybe since its an onroad car idk.

Street bashing ATM, there's no club or track in my area that I'm aware of.
