Thanks to a mysterious genius wizard on the subreddit its finally fixed his name was an0_1somthing its really hard
But yeah thx to all of you that tried with me

@QuantityPlayer you know when you put the vtol engine to throttle>.90 then you throttle to 90 the afterburner turns on but the exhaust nozzle dosent expand or open as you say it i need to make the exhaust nozzle open when the afterburner turns on too

Return to it in game and try to throttle to 100 percent youll see that the exhaust nozzle opens and the afterburner turrns on but when you put the engine to 90 percent throttle the afterburner turns on but the exhaust nozzle dosent open/expand until 100 percent throttle i need it to open at 90 throttle basically when the afterburner turns on the nozzle expands too

Shi this is too much words

@Quackmint I've downloaded it, no problem, can you give an explanation that's easy to understand, what do you mean? I don't understand

Im gonna accept it and just build with it and its still open if anyone fixes it i will take it and rebuild and you'll get a credit for it

@QuantityPlayer when i do that only the afterburner turnes on when its 90percent but the nozzle dosent open so the afterburner fire would just clip through it and thats not realistic can you download it and try it? So you can see

if true just put Throttle>0.90 in the xml input of one jet engine

so you mean one machine will be active when at 90%?
