what is the best way to set up drag brake on an electric car with a 3pk. i know i can just adjust my throttle trim but i figured with all the functions the 3pk has that there must be another way to setup drag brake besides throttle trim.

The best way to set your drag brakes is with your speed control since the 3PK doesn't have that feature. You can adjust the EPA, Expo, Speed, ABS, trim and mixing along with a lot of other things but not drag brake.

I see you're using Mambas, don't they have drag brakes? Mine does.

yes the mamba does have the drag break feature and thats what im running in both of electric , im playing with the T4 right now, i started to play with the mamba tonight on the couch just to get the dragbrake into the ballpark and its a good thing i did , the diff was making a horrible sound that apparently i didnt hear sunday over the other 9 trucks on the track lol. So needless to say i rebuilt a diff tonight instead of getting to far with the brakes.Luckily i had the parts on hand because our ponits series starts thursday night.Thanks for the info on the 3pk i looked everywhere through the manual and the menu on the controller for anything to do with dragbrake.

I did it once by re centering the throttle channel, move center further away from the brake.
