Hi, I have assignet buttons for DRS & KERS. They work as the required effect is there. I cannot seem to find out though, whether KERS and DRS is enabled by one click, and stopped with clicking again. Example: Is it 1 click to START KERS, and the KERS energy is used up automatically by that one click. OR 1 click to START KERS, and KERS is used up until you click the button again to STOP the KERS. Same as for DRS. I know with DRS that you need to be close to the front driver etc, but its more the standard procedure I am after. The reason I ask is because I can only see a reaction in the cockpit display when I click the buttons twice (sometimes). That can be because I use my old Logitech MOMO (old red leather version) that may or may not, register that I have actually clicked the button. Thanks.--- EDIT: I think I got it sorted out, I need to keep it activated.
