How do you adjust the idle setting on the JR XP662? I cannot get the idle trim to work if I have the throttle pulled all the way back. When I move the digital trim with the throttle all the way back nothing happens........

If I move the throttle up 2 clicks then the Throttle trim adjusts my idle setting. But, I have to be about 2 clicks up from all the way back. The bad thing with this however is that if when you pull the throttle back to idle if you go just 1 click too far the throttle pulls all the way back, taking out ALL of the trim I had put in, as if I had hit the throttle cutoff button.

At first I thought I could fly like that but I found today that it is extremely difficult to pull the throttle back to this precision idle stick setting when you cannot hear your plane all that well. I inadvertantly caused 2 dead stick landings trying to bring the power back to idle.

Am I missing something here? Or is this how this feature is intended to be used?

I have set the Travel Limits for both the High and Low end of the throttle with the trim and Sub Trim at zero. With these set I pull the throttle back to idle and try to adjust my throttle trim and get nothing.

Any help is greatly appreciated as I am contemplating sending this radio back.
