I have started using Manual Trim and have programed it to several hat's/buttons on my CH stick and throttle at different times because I though I might have a bad hat or button. No luck.
I can move the elevator trim to trim the nose down but for some reason I can not trim back up .BTW I am flying the 51D is this just something the 51 can not do ? I tried the same thing with the 38 and had not trouble. with any buttons programed.
Thanks
