Mamba x aux mode How does it work
 
I have a mamba x and a futaba 3pk. How do I make it so I have either my 30% drag or 100%? I have it set to my 3rd channel but I can only toggle drag 30% or of.
At 30% it isn’t completely locked in place so I have to use throttle to hold truck in place and I like that. But sometimes I want to be able to move around without having to give it a little throttle. So being able to put on 100% drag would be awesome.

When you have the aux wire set to drag brake in Castle Link it linearly scales the input to drag brake percentage. Servo pulses typically go between 1.0ms and 2.0ms. We scale over the range 1.1ms to 1.9ms. 1.1ms is 0% drag brake, 1.5ms is 50% drag brake, and 1.9ms is 100% drag brake.

On the 3pk, it has the display for showing the value of the third channel. If it is showing a value of 0 it is outputting 1.5ms. A value of -125 should be about 1.0ms, and a value of 125 should be about 2.0ms.

I actually figured that out eventually. So now I just switch the switch and I have 100% or 30%
