Product review (4 stars): very nice
I use this tx for my 180qx and its a very functional tx.  The only flaw in mine was the left stick.  Something seems to block it from going all the way down.  Throttle stays at 0 but the blockage is still there.  I love the sensitivity of the sticks. Micro movements is all it takes to fly my quad. I will not have to upgrade for quite awhile.
