I plugged the ESC in to the receiver and it worked great!

i answered a Craigslist ad and picked up a box of LiPo chargers for $50. The seller threw in a battery with the deal. I used it in a Hornet I picked up on Craigslist that has a hopped up motor. That motor used to drain a nicad battery in a few minutes. I got almost 15 minutes of continuous tun time with the LiPo.
