so I built up an xo1, got the roller, tires,motor/esc and all the components. At first it was crazy fast and awesome with no problems. But recently I have had problems with the steering being way too sensitive. I know you can use the app and traxxas link to fix this but either its not working or I don't know how to do it. I used an old futaba servo I had lying around. Any thoughts or suggestions would be appreciated
