Thanks for your help Leo and may I ask one more question of you. Tech support at Cox seemed to think the common sense battery may be too weak as it did not have a continuous discharge rate of 18amps. I'm trying to get up to speed on these new Lipo's and esc's etc.,so please bear with me. Is it possible the common sense battery will limit the output of the motor or, will time at full throttle be limited? I apologize for my lack of knowledge but you seem to know this stuff pretty well. Thanks again!
