approx 1740 in 1 go is about right.
I dont think many people run a front head as it adds too much weight too far forward and causes the car to keep on turning and it will effect it more jumping, i think the weight is from under the servo, speedo, and a couple in the odd pod here and there to balance things up. the servo weight comes out in the wet and goes under the cells
I had thought about running lighter but with the weight at the extremeties to get the feel the same but it just doesn't feel quite right in practice. The heavier car just feels much nicer.
