Hi, Just bought a Challenger from HobbyZone and put together,but I noticed once I charge the battery and spin the motor up it lose's power in about 3 minutes. Just wanted to know if it is my battery or if I am doing something wrong. I am charging it on the car lighter as it calls for and letting it charge until the charger stops flashing and goes solid red. So can any one help me get off the ground please??????????????
