having exact same problems listed here, none of the solutions worked but I knew they would not because it's a problem with this mod. At first I thought yes it was a keymap problem or a config prob but now that I see all the other complaints here and how janky the engine start system for this B52 is god awful. I know it's a lost cause and this is not working right. People saying to try fixes like gently tapping CTRL+SHIFT+42+ALT+BACKSPACE+ANYKEY 5 times while holding one hand on the top of your head but none of that works. The engines keep starting and stopping themselves over and over, nothing makes the plane budge other than holding CTRL+SHIFT+F4 and letting go of it kills it. Also it's annoying that this mod then makes all my other planes cycle their engines down and I have to go through the startup process for each one (which they never fail to do by the way) but no matter what this broken mod will not work and plane won't start sorry to say I will look to fly one made from another place
