Just wondering if you guys could give me some pointers to knowing if I am ready to get LiPo for slash 4x4. My mum is saying that I shouldn't get it until I go to the track and know for sure that I can control even the power of the slash 4x4 ultimate stock battery; the 4200mah 7-cell Nimh battery. Would that be a fair demand? i think I am ready cause i've been in this hobby for like 3 years now, and find Nimh batteries a bit too slow for me now. Thanks in advance guys!
