I'm happy with the 4S runtimes and speed for now. Shopping around for 6S, and unlike the 4S where it's cheaper to actually get two 2S lipos, I was wondering what lipos are people using for 6S? I have options of 30C or 40C discharge with 5000mah... anybody have problems running 6S? Does the 6S lipo fit in the battery tray? I'm not the type to floor the car, I think I have a good understanding of throttle control. I floor it when needed and would like to have that power available when wanted. What are your opinions and recommendations... This is purley for urban bashing this 6S...
