i think, i had the same problem in the past. i now use an own axis for "reverse". below 80 knots i put reverse and toggle to idle/none (i had to calibrate the axis, that there is really no thrust left). below 40 knots my rpm is low enough and i use a button to turn off reverse. by the way: data.x-plane.com is using NAVDATA 2012.08 today. do you really use 1212? and jrollon 1.5.2 delivered NAVIGRAPH 1208? i thought it was 1108, but i'm not sure. x-plane 10.11 crj 1.5.3 navigraph 2012.10
