Hi everyone, I've always had this problem on FSX and I'm finally actively going to try to get it sorted out. I'm using a Saitek X52 Flight Control System and I've bound reverse thrust to the button on the top of throttle, I've done it through FSX control settings and have the button set to full-repeat. However, when I land and engage reverse and hold down the bound button, it starts reverse, snaps back, and starts again. I've seen videos of people where it engages and the N1 spools smoothly like it should when reverse in engaged and I was wandering if there is any trick in achieving this? Recently got the NGX so want the experience to be as immersive as possible :) Many Thanks.

I have mine on half repeat. Also make sure you don't touch the throttles at al because any movement should trigger them to go back to normal.

I've just tried setting it to half repeat (throttles are at idle) but it seems to make the problem worse, on the NGX (and on any other aircraft), it changes to 'REV' on the engine display but the n1 stays at around 25-30% and still doesn't want to spool up.

I've had the same issue in the past, and found the best way to fix it is to use FSUIPC to control the throttle hardware, it does a much better job at setting a dead zone than the FSX calibration mechanism. A proper dead zone is a prerequisite for getting a steady reverse thrust, otherwise if your hardware throttle has noise or is badly calibrated reverse thrust will not stick. And I had that steady reverse thrust for all my addons, until the NGX, since apparently it doesn't play nice with FSUIPC as an axis controller/calibrator. Now i'm in the same boat as you, trying to find a way to get back a reliable reverse thrust. I even tried all kinds of dead zones in FSX for my CH products throttle, but nothing is working. It's driving me %$#$% nuts!!!!!!!!!!!!!I really wish PMDG had FSUIPC joystick calibration for joystick axis in mind when they worked on the NGX, as it is so much more accurate and flexible than having FSX in control of those settings.

Thanks for the advice, you're right and I've solved the problem. I unplugged by Saitek X52 completely and just tried engaging reverse with the F2 key, and what happens....perfectly stable and smoothly spooling reverse thrust. So I plug the X52 back in and go in Windows 7 joystick calibration and see that on the throttle axis, there appeared to be a dead zone on the idle detent of about 10%, looks like some sort of hardware issue. So i've removed the dead zone from the axis and the result... proper reverse thrust!
