XRAY - Model racing cars

if i where to try 4 cells in the t2'007 with 19 turns like komodo dragon, what gearing would it like? it would be for drifting plastic tires.
so theres not so much load on the car.
or would you really need a modified for 4 cells to make some power?

i tested 4 cells (gp3700) with cobalt 12*2 flatwire yesterday and it felt good, not to much loss of power and the car being lighter felt nice
so i'm gonna keep doing it. but now i can imagine that a 19 would be awfully slow.

i have tested it with a checkpoint money (19) and its too little power, with the cobalt however its nice.
