with the discussion of set up- I set my brakes on the ESC to 100%. Then I use the EPA on my radio (Spektrum DX3R Pro) to turn them down as needed. I think this makes it easy to adjust brakes from track to track and in changing conditions as the day goes on.
Is this a good idea, or is it better to set them on the ESC? I have not experienced any issues, but thought I would ask.
It's fine. However in 1/8 100% can break the car lol.
So if you do reduce it on the esc, you're giving yourself better resolution or "smaller steps" when you do use your Epa's on your transmitter.
