Idle up shouldn't matter. click the wheel on your Tx to go into the menu and scroll down to 2. In there, you will see aileron, elevator and rudder. I would set position 0 on all 3 to 70% + 35%. You will have to make sure your switches, all 3, are in the 0 position. Then, flip all 3 switches to position 1, and set it to 100% + 40%. If you are learning, forget that the heli has an idle up function lmao. It will get you in a lot of trouble very quickly. If you have not watched it, watch the video below for my explination on DR and Expo for the DX6i.
