Ok just setup a Kingtech 140 on my JR28x and was wondering if I did it correct. I did the teach with the throttle trim in the middle position (for off) and then set the failsafe with the throttle trim all the way down. When the trim is in the middle the gsu reads 0 but if I remember correct on my Spektrum the trim had to be all the way down to read 0 and you had to use endpoints to set failsafe so it would be out of range. If there is a better way to setup the radio please let me know.
