RE: does everyone here use lipo?
My Slash 4X4 runs only LiPo, as all MY stuff is Dean's connectors so i have intentionally left me no other options haha Actually just got a new charger and LiPos from HK today!
My fiancee's Blitz still runs NiMh and Traxxas connectors on all 7 of her packs and 5 chargers (damn girls kinda spoiled), and even with her truck running MMP ESC and Velineon 3500 motor it works very well.
LiPo is nothing to fear however, just dont stab it and you should be fine!
