So I have this helicopter, I add two twin engines, so, I put in Activate3 and4 for the input, I turn on my helicopter, and than when I land, I try to turn off the engines, but they don’t turn off. Is there some kind of reason that they don’t turn off after I turn them on, because I have to restart the game (not simpleplanes in general) I could use all the help I could get. I want to surprise my uncle who is a pilot today and show him my masterpiece.
