Mapping throttle control for engines 3 and 4 are still not working. If 4 throttles are mapped, throttle 4 becomes the throttle that controls engine 2. (with throttle 1 controlling engines 1,3,4) Controls for engine 2 and 3 do nothing. So, cannot map controls for engine 3 throttle and engine 4 throttle. Whatever second throttle is mapped, be it throttle 3 or throttle 4, it becomes the throttle control for engine 2. I have an Logitech x52 pro throttle. I map the main throttle as engine 1, the slider for engine 2. I used to also map one wheel for engine 3 and the second wheel for engine 4. Controlling 4 engines on bombers helps in landing or governing speeds for bombing. But after patch 3.03 release 7, can only map 2 engines. I assume also if someone has a 4 throttle controller, only 2 would work.
Also after patch 3.03 release 7 controllers have become backwards and the 'invert' box needs checked now.
