FMS - update. I did get a version of the FMS downloaded and working. I have to have the plane in flying mode or it never gets off the ground. I did use a Gravis BlackHawk controller. The only thing I can,t seem to get the channels working good. The Pitts flys the best, but all planes move with a very slow rate and seem to jerk in 3 second intervals. I am going to try more RAM first. I may try a Geforce vidio card next. Any more ideas will be welcomed. Thanks Captin John P.S. I was able to fly inverted because nothing moves fast.
