I use 1/10 for the pulse rate, this is the anti-lock brake function. You may like a different pulse rate. Make sure you have the steering mix going the correct direction. Also, if you see the Proportional Caption it means you are in heading hold mode. I have found that Heading Hold works best, but you may prefer proportional mode. If one brake is pulling significantly more than another you can adjust the brake force on each wheel indepentently pushing the Limit button.
