I do not know what did it....but just handing the transmitter to a friend so he could fly my aerofly Deluxe, it went goofy ....all the plane would do is rev up and crash. I went to the assignment screen, and every thing was messed up. Could not seem to correct it, so I removed the complete programe and re-installed it. I did get it back working good. Now I got smoke!!!! My friend sure likes it. I think he wants one also. I/ we hope there is a solid fix for the cable problem. May have to get a new cable if Ikarus comes out with one. A fun sim...for sure!!!!!! SEE Update in new reply Thanks
