OK, I dont want to create a new thread so I am writing here. I have an 1515 2200kv in my emaxx. I calculated that that speed vith my 17t pinion is 53 mph and if would have 1518 1800kv I would need 20t pinion to reach the same speed but with higher gearing I reduce runtime, increase heat on the motor and I think acceleration would be about the same because of the pinion. So can someone tell me why would 1518 be better?
