2200kv MMM

[scooterboy]

Hi I'm running a 2200kv 1515 1Y motor in my converted lightning stadium pro, 14t pinion 5800 4s lipos with lvc at 3.2 the finals where i race are 15 minutes and unless i nurse the car i hit the lvc at 14mins. I'm only touching WOT for a split second on the main straight, would gearing lower help (i ran a 15 tooth 1st time out and hit the lvc at 14mins 30 seconds but had a 4 lap lead)
punch is 75%
timing 0
start power low.

would a 1800kv 1512 1.5Y be man enough for a truggy as i have the chance of getting one for a good price and would this give me 15 mins at full race pace(with the same 4s lipos). (tbh its won every time i've used it but i would like to be able to run at the same pace as the heats in the final)

cheers

Darren
