Drag brake.. well 1st off someone posted it goes into affect in neutral Throttle
well thats wrong .. drag brake on most esc goes into effect the instant the throttle is no going +.. the second u move your trigger towards neutral Th. it will engage..
as far as using it many drivers use it even though they might tell you they dont..
I personally Never use it tried it and dint like the results..
pro and cons
can teach you to be a faster driver but adds heat to esc n motor both and uses those needed mah in a longer race 7-10 minute main..
so set it up give it a try..see what you results are .. good luck. monitor the HEAT..
