Just make sure you set up the LVC on the ESC. Don't want to ruin any batteries now. That is an excellent car. You may have to turn out the clutch some. I have the XL 5 with the Sidewinder 4600kv system and a 25C 2s 4000mah Lipo battery. It is so much better than brushed. Way better! Enjoy it. Mods for it are cheap and well worth it. Get some aluminum caster blocks. I'm not sure if it has them already or not. RPM front and rear control arms are excellent also.
