I have had the same trouble. I have been using it fine with prop aircraft for the last couple of days. I found out tonight when I try to load a jet or helicopter it now sees my JR Centry 7 radio as a 3 channel. Also tried a JR Unlimited and a JR 388s. I had started a post last week about this only to find it had been deleted by someone elese. Hopefully tomorrow it will work fine for the prop aircraft, at lest that's what happened last time. I wonder if this has something to do with JR radios?
