i got the Losi LiPo and charger combo, picked it up for $50 at my LHS. I like it because it takes an hour to charge it and the charger has 2 LED's that let you know when it's fully charged. I got a 20 minute run off the 1st charge, they say the time will increase with the more times the battery is charged....but i think i fried my steering servo, gotta go get a new one tomorrow
