Hi, I purchased from X-Aviation the airplane "Take Command IXEG 737 Classic", and until this moment I cannot run it, because the engines power increase / decrease doesn´t work. I had read a lot of commentaries about the problem, but no one fixes the problem. Now I request from you the final solution for this problem, or send me the refund of my money. It´s a little expensive to have an USD 49.95 as an static 737.Waiting your prompt answer and solution.Regards.José Ureta
